  • 2024-Feb-14 to 2024-Feb-15 / 2 days / Hiking / SOBO / RR / Joscha

I combined section 9 to 12. It took me 7.5 days in total.

Day 1: RR [0.0-13.7]

Water at all Water and Ford Waypoints I passed today. But at km 3.1 it's not much more than a trickle. The hotspring at km 6.6 is a little dirty and has some cow poo around. But still worth a little bath.


Day 2: RR [13.7-32.9]

Water at all Water and Ford Waypoints I passed today. There is still some snow on the southern side of the Pass (km 27.6), but you can walk around it on the eastern side on a step gravel slope. Be carfull walking down. There are a lot of lose bolders. I didn't take the trail out of the gulch at km 31.1 as Hannes suggested. Its possible to continue in the gulch but I had to get rid of my hiking poles at one point to use both my hands to climb down a mini waterfall. The Hotspring at km 32.0 was pretty dirty and rather warm than hot. I did not went to Ranquil and continued directly with section 12 at km 32.9.


  • 2024-Feb-10 to 2024-Feb-12 / 2 days / Hiking / NOBO / Section 12 on RR - Guallali / RR + Option 4 until the pass / Alex & Christophe

We directly went on this section after section 12. The way up to the pass in the river wasn't easy and took us more time than we thought. There was only one time were we had to go out of the river to find another way as Hannes as already explained.

Once, the pass was behind us, all was easy and we really enjoyed Hot Spring, Camp {11} [6.6/991] (Poorly Maintained). It was clean, maybe recently digged and nice after a dusty day on the trail.

We also ended this section with a light resupply in Guayali and a perfect almuerzo before going on section 10 in Shop {11} [0.1/951] (Mini Shop).

  • 2024-Jan-16 to 2024-Jan-18 / 2,5 days / Hiking / SOBO / RR / Hannes


Nothing worth to mention, which has not already been mentioned before…except the gulch after the pass. At around -38.110511, -71.087826 it gets pretty straight, with fast water flow and river gets deeper and you are not able to figure out what comes after the next 50m because you do not see…I went out there from the river bed and took a trail on the left side (with some BB for the first 20m), you will see this trail…at around -38.111291, -71.087135 I entered the gulch again. Choose yourself. Afterwards I went out to Ranquil and then to Maximilianos and Anna’s minishop at -38.24995, -71.23238. They let me sleep there. So nice people! Convinced Max to sell Gas in his shop, so should be available soon there.


  • 2024-01-13/22 / 7 + 3 days / Hiking / NOBO / RR (sections 12 & 11) / Coline

I hiked GPT12 and 11 in a raw, so to reach the Pelehue hotsprings instead of going to Troyo for resupplying. This ten-days trail was really a great experience ! Sometimes terrifying, but not dangerous – as said in another post.

My "goal" was to reach each hotspring marked on the map (4). My favourite was the one at the end (near Guallalí), because I meet a chilian family on vacacion there and they had dig the spring large enough for them six ! The baños Coyucos "moved" : there are just below the Camp {12} [20.4/1625], where one's finds a bench, a table and a place for firecamps. The termas Pelehue definitly disappeared, but the view there is very scenic. The Hot Spring {11} [32.0/1428] are a bit dirty, sibce ciws like to lie in them, but one's can easily "clean" them a bit and enjoy a warm bath : I choosed the uppermost, and therefore warmer (Yes, there are two).

The sections 11 & 12 were beautiful to me because of the passes... and difficult for the same reason. First Pass {12} [68.0+0.2/1909] was actually Ok, because the way (northbound) goes slowly up. The second Pass {12} [57.4/2180] was more difficult, due to the mud, and particularly on the way down for me, since I lost the trail and found myself stuck in a forest of small trees.

The real DIFFICULTY for me was the last Pass {11} [27.6/2174]. After nine days, my body and mind were really tired. I forgot the advice of previous walkers and tried to go up through the forest (because of the sun exposure in the valley). I lost an hour and had to go down to the river. Moreover, the last 100m, with the snow and rocks, were doable, but the idea of sliding really scarred me.

Something else scarred me at the beginning of my journey (and it shouln'd have...) : it was the attitud of some "caballeros" towards me, a solo female hiker. Most of the "caballeros" are nice and will help you, but some can be really insisting. (I had to yell at a man asking me for five minutes if I wanted a compagnon for the night... It was 3 a.m. and he had wake me up with his light and dog). But he was not threatening, "just" asking over and over.

Actually Laguna Verde and Laguna Escondida (where I met those insisting men) are still nice memories to me ! By the way, I recommend the beach on the south side of Laguna Escondida ; the north one is skinny, inhabited by mosquitos and very "escondida" (hidden) in the bushes.

What else ? I avoid the Pehuenche Extortioner taking CC road, and it went all good. There is a bridge some 120m west of the Ford {12} [45.4/1039],... whereas there is no more bridge at Bridge ? {11-C} [0.3/1109], but it seems very easier to cross the Estero Quillaylemu there, rather than on the RR. The river crossing is Ok, and there is plenty of water all along the way. As for the resupplying, I don't know about Troyo, but the only shop in Guallalí is very small (no bottle of gas or tobacco for sure). The woman who manages it is very nice though : she indicated me that a bus (with more food) would pass at 8 p.m, she invited me to charge my bateries at her place, let me have a nap, while she prepared me a delicious dish ! I had nice time with the younger kid, and even spend the night there at the end.


  • 2024-Jan-06 to 2024-Jan-07 / 2 days / Hiking / SOBO / RR - {11-C} - RR / Lilian

Dirt road walking from RR km0 to "Bridge? {11-C} [0.3/1109].

Lot of nice water flowing across the road.

Hot spring,camp RR[6.6/991] : i didn't go to check the hot spring, i saw it from high at road, there are lot of cows surrounded and standing in the spring, look like they are enjoying it. And a beautiful grassland is good for camping just beside it. A dirt road just before water[6.8/1035] will lead you to there.

RR Km11.7 : beautiful view begin!

If you follow the dirt road walking, it will lead you to Bridge? {11-C} [0.3/1109].

Bridge? {11-C} [0.3/1109] : no more bridge here, cross the stream just above ankle. After you cross it, CC back to RR.

Ford RR [18.0/1199] : Crossing of Río Chaviquin, when you arrive the river, upstream 5m and look at the riverbed underwater, a rock bar there, about 45° downstream to the other side. Water is above half of thighs at noon, luckily flowing not fast and not strong.


After the crossing, sometimes the trail easily mix with cow paths.

Water, gate[19.9,136] : locked. Not a friendly gate, not easy climbing.

Km22 : go into a wildfire dead trees area, for now the trail conditions still ok, but after some years they all fall down, i think it'll be difficult to follow between blowdowns.

Km23.2 - km23.8 : blowdowns area, RR become difficult to follow, look like some reroute here.

Ford[24.3/1688] : flowing fast and above half of calf at late afternoon. Flat spot can fit 1 tent after the crossing, surrounded by forest.

Camp[25.1/1846] , Camp[26.1/1957] : both are beautiful camping spots, but no wind protection, also very wet as now, lot of tiny streams flowing nearby.

X[26.8/2036] : if you don't look at the GPS, it is a "must" miss junction.


Pass[27.6/2174] : no need to step on any snow at north side. Still covered by lot of snow at south until km28.6(1850m). You can sit down then slide down, but some rocks appear at 2060m, better control the sliding direction otherwise your butt will cut off. I keep skiing down(with my trail runner) until almost the end of snow. You can walk on some stable ground start at km28.4(1910m). I think this part is difficult for NOBO if in heavy snow conditions.

Mostly there are no trail, all walk by your own way in the valley. Maybe you'll find some nice trail like the one at km29.15, but all of them will disappear in 5min.

You will cross the same river 21 times until you met a beautiful trail at km30.8. All the crossing is easy, mostly just calf, all under knee.

Except km30.15, it is a small waterfall, valley become narrow, no shore for go around or stepping on, I don't know the way to go down. So i turn back to km30.1, follow the trail shown in OSM, climb up on the east side of valley. But when i going down back to the valley, look like a short part of the trail is landslide away, it becomes very steep to go down, be careful.

km30.8 : trail, easy walk start.

Km31.3 : locked gate with wire fence, you can go around it at right side.

Hot spring? [32.0/1428] : nice spot! 2m x 2m pool with good temperature water(about 50°c), although it's not deep also grey colour, but it surprised me, just like a reward after so many cold feet crossing! Some flat spots nearby. I met a friendly family here too!

Ford[33.2/1403] : crossing of Rio Ranquil, looks like up to thighs and flowing strong. Log crossing at upstream 40m, but not easy. I saw some footprints for locals crossing it, so i crossed here. After the crossing about 100m is a big fire ring and a camping spot can fit 1 tent under a tree. 80m more is a roundabout for dirt road, you can camping here if need, because the dirt road is damaged so no cars coming.

And then dirt road walking all the way down. Maybe possible for hitching out on weekend if you are lucky, i saw some people driving to here for picnic when i was walking down the road on Sunday.


2023-dec-23/ 2 days / hiking / SOBO / RR / Lukas en Tess

Section 11 went fairly smooth. We followed the advice of the wiki to avoid option 1. RR was perfect, coming through some awesome forrest on the way up, we found wild cilantro and some other stuff. We camped just across the ford on K24,3 for the pools. The pools are good, but I think the next campspot on the map at K25,1 is definitely the most beautiful on the route. With awesome waterfalls not too far to venture into. The pass was no problem, lots of snow on the other side but never to steep. We sat down and went for one of our fastest decends jet :p Then the pickle began, we needed to restock for section 12, but the busses are only monday, wednesday, and Fridays. And not on public holidays like monday the 25th of dec!!! We tried hitchhiking, but there was no one passing except horses. In the end, we found a new minishop on the way to Troyo {11-5f} 14.3 k from the end of GPT11. The owners just moved here from Santiago. Maximilian and Anna are probably the nicest people we have met on the trail so far. The shop has everything you need to resupply except gas (maybe in the future). They took us in and we ended up staying with them for 2 days and celibrating Christmas together with some of their friends. It was great!


2023 Dec 15 / 1 day / hiking / SOBO / option 05 + 05F + hitchhike / Frans

Reading all the stories and in combination with the upcoming bad weather made me skip the pass and decide to go to Troyo or even Lonquimay and rejoin GPT 12 later. Beautiful walk through the valley tho! Really enjoyed it.

First rivercrossing after 1.5km, water was pretty strong and for me (194cm) reached my waist even before I was halfway. So decided to turn back and look for a better spot. About 150m downstream the water splits in 2 streams. Much easier, didn't came any higher than my knees. So easy to cross here.

About 200m before GPT11-05A End there was a gate and a man sitting in front of it. His wife joined immediately. My western interpretation of their verbal and non-verbal communication was they were grumpy and annoyed. But I could understand probably less than 5% of the words they said. I tried to smile and wave, thank them and say how beautiful the area was but it made no impression at all. After taking pictures of my driver license and paying 10k CLP they let me through and continue (and I knew this would happen because it's written here before).

Got a ride to Lonquimay after joining the main road to Troyo (11-05F) by the first vehicle that passed by.


2023-Dex-02 to 2023-Dec-04 / 2 days / Hiking / NOBO / RR / Jens

We combined the two stages 12 and 11. The hot springs after about 7 kilometres gave our weary bones a little rest.

I had tried the ascent to the pass along the left-hand side. I followed a trail for a few kilometres, but at some point it ended in bush bashing. The better route is probably through and along the river.

As there was still a lot of snow at the beginning of December, crossing the pass was not easy. The last 100 metres in altitude were particularly steep. I can imagine that the melting of the snow could lead to avalanches in the coming weeks.

On the other side, I had no further problems. There was still some snow, but I could either avoid it or walk right over it.

Water: Many options

Camping: Many options from two kilometres before and after the pass.

2023-Dec-3 to 2023-Dec-5 / 3 days / Hiking / NOBO / RR + option 5F + option 5 / Yannick & Nolwenn

We started section 11 and turned around just before the pass because there was too much snow for us and we felt it was dangerous. So we then took the option road to go to Troyo ( rest day) then to Guallali.

- Water : all markers are good and even more water present

- Snow : lots of snow on pass, from km 29,14 to km 27,57.

- Camping spot : easy to find, the natural hot spring matked on the map is present and it's easy to camp next to it

- River crossing : on RR, following the river is easy from km 30,8 to km 29,12, stay in the river bed. It's not worth it to get out of the river and try to found a way around it. We did it and regretted it. | Rio Chaquilvin on option 5 was easy to cross. (The cable car is locked)

- Weather : Sunny

- Option roads : option 5F | (1) gravel road, for us on a Sunday, we didn't encounter a car for the first 12 km then got lucky and got a ride to Troyo - we also got an easy hitch from Toro to Puente qcontraco. Option 5 | (2) easy track. From km 7,15 ( fundo los Guindos) to km 1,2 you are in Mapuche territory. At km 7,15 , two guys with some big knifes hanging on their belt asked us to stop. They were a bit cold and not really welcoming. They explained to us that they were retaking their land and therefore needed to register everyone who was entering.They took a picture of our passport and let us go after saying that we should go to the house at km 2,45 so someone there could help us cross the river ( Rio Chaquilvin) where there is a cable car. Once we arrived to the house, a woman ( really not nice) blackmailed us in order to give her money because we were on her land. When we asked how much for the fee she just said " what do you got ? ". So then we negotiated a little bit but quickly gave her some money ( 7000 pesos), but she was asking more.... There was a big dog behind her and we were feeling really uncomfortable and just wanted to get out of the situation. She didn't help us cross the river and just said " if you die it's your responsibility '.

- Warning : Mapuche land - read section ' option roads' | A lot of snow at the pass on RR.

Season 2022/23

  • 2023-Mar-05 to 2023-Mar-05 / 2 days / Hiking / NOBO / RR / Iris, Alexis

Continued directly from GPT12 so we started at the end of RR-TL-V {11} [31.3+1.5] . We followed the RR for the whole section.

On day 1, for RR-CC-A {11} [27.6+3.3], you have to stay in the river stream for the whole duration. You will find plenty of water because you walk in it, and nice pools and little cascade if you want to take a bath. Leaving the stream for higher up is not a good choice : every time we tried it was a mistake. We camped at Camp {11} [26.1/1957]. It was not protected and the night was very windy... Not our best choice.

On day 2, we continued until Guallali following the RR. The trail around Km15 transforms in a MR that leads you to the village without even checking the GPS. There, we found the minishop that had limited resupply options (we bought lentils, cookies, snacks and cola). We checked in with the carabineros that were friendly and sayed we could camp wherever was wind protected. We opted for the football field which is a nice flat and grassy place.

Not much to say about this section, we found the end on the dirt road relatively dull but the beginning in the mountain is awesome


  • 2023-Feb-11 to 2023-Feb-12 / 1.5 days / Hiking / SOBO / RR (option 01+ off route) / Natalie&Tomáš

Combined GPT 10(01)+11+12 Day1 Slept in Guallalí in the growth as others have described but still asked the shop owner first for permission. Carabineros were nice and told us we did not need to check in although the sign says "obligatory check". Pedro at the mini shop is also kind and willing to help hikers although there is only a handful of items in his shop-bought some sweets. Pedro also told me that option05 to lonquimay would require you to pay 10mil from the locals. We took RR. At this time of year the road is the "dirt-dust type" but still fast until Estero Quillaylemu (14km) which makes for a nice rest. Tomáš checked out the hotsprings at 6.6. There is a table and a pool of nicely hot muddy water directly next to a river. Better camping site than in Guallali. After the Estero Quillaylemu the track gets harder to follow but becomes beautiful after the ford and bend towards the pass. Lost the trail a couple of times but found lots of wild quinoa. Camped at 25.1 behind a boulder by the river to cut the wind, camp at 26.1 looked nicer.

For the pass we followed the ridge for as long as we could (option 01) and it was fun and straightforward. Luckily, although the winds were strong that day the ridge was almost windless. Made our way down similar to Will. Got off the ridge here; -38.10270, -71.07250 (later than indicated by the GPX), headed to a small dry gully next to and below the "greyish" dirt here; -38.10359, -71.07282, you had to use your edges as the ground was hard"grit". Entered a small creek bed here;-38.10604, -71.07538 and followed it (some water) until it turned into a scramble. At that point we climbed back up to our left (East), moved south until we went down and up our final gully, just underneath 01B. This last gully was easy as Tomáš found a soft spot, somewhere around here;-38.11039, -71.07474. After this point it was easy to connect to the main route. Just the section up to here from the ridge is problematic - maybe two km. Probably fastest would be to go down the regular route and take the first option left, which is probably a trail and only means about 300 m of additional climbing. The route as mapped by the GPX files (option01; second half of the traverse) looks quite steep and exposed and does not save much elevation. It is probably possible but to us from below it does not look worth it.

Lastly there are water sources on the other side of the ridge (SW, the hard side) before the hotsprings if needed.

Continued onto Section 12 towards Banos Coyucos for the night.


  • 2023-Jan-27 to 2023-Jan-28 / 2 days / Hiking / SOBO / RR / Johana & Matouš

We camped near the ford on the 18th kilometre (just about 20 metres upstream is a great place to take a bath in). The next day we made it all the way to the end; however, it was an ordeal. The view from the pass was jaw-dropping and parts of the path leading up to it were shaded by beautiful trees, but we feel like the horrible descent (we were doing the regular route) made it not worth it for us. Despite the fact that we were lucky enough to have the best conditions for the descent (only some snowpatches at the top, sunny weather), the terrain felt ankle-spraining. The wobbly stones kept sliding down and it required a lot of focus. We went down through the canyon and after the point where you need to go above it when it becomes too narrow we went down the wrong way and I fell down clutching at straws (literally) not to fall down. So it might be better to go through the river..? To be optimistic, the last part of the path was beautiful again. We hitched a ride and stayed with a really nice family that took us to Lonquimay the next day. It's a nice bigger town with a lot of possibilities to resupply. There are really buses only Mo-We-Fri from Ranquil.


  • 2023-Jan-17 to 2023-Jan-18 / 2 days / Hiking / SOBO / option 1 to the Termas del Pelehue / Will

I took the bus to Guallali, which took me past the Carabineros and directly into town where I set up in the standard grove. A bit after dark two carabineros showed up at my tent. Intimidating at first, they were very friendly after I explained my plans. They just said that next time I should make sure to stop and report to them on my way by.

The section starts out with a not very interesting road walk, but suddenly became super beautiful 15ish km in. I camped at 25.1, a somewhat sheltered spot by a stream, where the wind rattling my tent made it hard to sleep. A few arrieros came by during the evening. The 26.1 campsite looked similar.

The horse flies reappeared as I got up closer to the pass. Had flashbacks of sections 7 and 8, trying to determine whether each stab was a horse fly or a burr or a paranoid hallucination. My theory is that they've migrated up to the higher altitudes, now that it's later in the season.

I took option 1 (diverging a decent amount) to join up with section 12 at the termas de pelehue. It was tough and slow going, taking around 3 hours, but I really enjoyed it. I planned my route to avoid horizontal slope traversals so I never really felt in danger of a serious fall. I did still slip a few times, cutting up my hand a bit.

I started out with the ridge walk from the pass. Would have been great walking if not for the absurd winds, I spent most of it slightly to the south below the ridge. The slope was pretty gradual there and not slippery. I then went down past the two grass patches following the route on openstreetmap. I descended to the south all the way down to around 1875m, along a stream around 50m to the east of the openstreetmap route. It was easy rock walking at first, but turned into some tricky hands on scrambling as the stream got bigger.

I wouldn't recommend it if the flow rate is high. Then I climbed back up to the final stretch of the main option route. The climb was steep at first but with enough vegetation and solid rock in the slope to get up. Everything after that was easy, more or less.


  • 2023-Jan-14 to 2023-Jan-16 / 2.5 days / Hiking / SOBO / RR / Martin & Helena

From Guallalí there’s a gravel road for first few kms, easy walking. We didn’t check the hot springs in a hot day, but someone mentioned it is fine. All the fords were easy. We camped around km 21 in a little forrest. The ascent to the pass is pretty gradual and we enjoyed it really. Based on previous comments we chose to stick to the RR which turned out to be a good decision. There was still quite a lot of snow and the terrain is more technical, but it just requires focus. We walked on the right edge of the snowfield and slided down in some parts. When we reached the river we didn’t walk at all on the snow but rather on river banks or even in the river itself. Closer to the junction we once or twice followed the alternative dotted line that is marked in our maps - it just goes higher up from the canyon and back. After the junction we continued to GPT12.

Contact: @martin_hanzelka @helenneka


  • 2023-Jan-13 to 2023-Jan-14 / 2 days / Hiking / SOBO / Guallalí - Termas de Pelehue (junction GPT 11, option 1 and GPT 12) / Anna & Christopher

In Guallalí we camped at the same spot as Veronica after arriving around 20:30. The first day there is a lot of walking on dirt roads and good paths, so the km went by quickly. We camped at the ford waypoint [24.3/1688], where the way passes a small creek. It has some natural pools, which are amazing to take a bath.

The next day after arriving on the plateau there is a CC part, so keep an eye on your navigation device. When we reached the pass we accidently went the wrong way and ended up taking option 1 to decrease the detour. Bad idea! Better don't take option 1. There is almost no path, its very steep, a lot of scrambling and there was one very stupidly dangerous descent across some gravel/rock part. It took us around 3,5 hours to cross option 1. We would definetly not do it again. We directly continued to section 12.


  • 2022-Dec-25 to 2022-Dec-30 / 5.5 days (GPT11 + GPT12) / Hiking /SOBO / RR + OH 2 / Véronica

Route: Guallalí - Junction to Section 11, Option 2 - Ridge Las Monjas - Junction with GPT12, RR-CC-A {12} [12.9+3.5]

Ralco is a good resupply town, the smaller supermarket had camping gas. Took the bus back to Guallalí at 5 p.m. for 1,000 clp, arrived around 8:30 p.m. I camped in the same araucaria grove as the night before (via the wooden gate next to the escuela). Good and clear path in a pleasant valley, river fords easy. Found some ripe berries/brambles along the trail that were delicious.

I decided to opt for Option 2 that goes east of Cerro Dedos. I was worried about the likelihood of snow on the steep south side of the pass (2174 m) on the regular route. I didn't need to stop in Ranquil, so figured it was best to stay high on the mountain and take either Option 1 or Option 2 to connect with GTP12. After reading the comments from other hikers, I knew I didn't want to take Option 1. A scree traverse on a south-facing slope didn't sound appealing, especially if you factor in lingering snowbanks this year. So I thought Option 2 would be best. A detailed description of my experience along that route is posted under "Optional Routes" ("its directly under this post - modified by Joscha97") . The gist of it is - it was very technical, not much solid footing, lots of exposed scrambling. In a couple spots I genuinely feared for my life. Would not do it again. Please stay safe if going that route, and I would definitely not attempt it NOBO!

Took 1.5 days to meet up with GPT12 at km 12.9

OH 2: The trail is good and easy to follow in the initial valley once it splits from the RR. There was no puesto at the second "puesto" waypoint, just remnants of old fences and corrals. Good place to camp, sheltered from the wind. The start of the CC section is an annoying but thankfully short bushwhack to the treeline. Afterwards it's straight up to the top of the ridge, grass turning to scree/rocks higher up. Steep, but quite doable. Once at the top of the ridge, this is where my troubles started. The ridge is not nice and rounded, but very narrow and jagged, with vertical, rock outcrops/spires blocking the way frequently. You have to go around most of these obstacles (impossible to climb over), and this is the most dangerous part. To go around you need to descend back onto the nearly vertical scree slope, traverse around the rockface, then climb back up to the ridge. All on the most slippery scree/gravel I've ever experienced. It was all extremely precarious. Climbing back up around the very first obstacle, the scree was so loose I was on my hands and knees scrambling upward, trying to climb faster than the rocks falling under my body. One of the most frightening situations of my life honestly, I felt like I could have gone down with the rocks like an avalanche. After miraculously getting back up on the ridge, I couldn't stop shaking and was almost in tears. Couldn't believe what I'd gotten myself into honestly. And then came more scrambling and clambering. Poles were useless, I was using my hands the whole time. I can't stress enough how loose and unreliable most of the rocks were. Very, very difficult. Would not attempt this northbound, ever. And thank goodness the weather was good and calm too. The views were spectacular, out of this world, but not worth risking my life for, and I wouldn't ever do that section again. Don't know if Option 1 would have been better. At least snow wasn't an issue with Option 2. If I had to do it again I would stick to the regular route, go down to Ranquil and climb back up GPT12 via the RR. Anyway, south of S 38° 06.903', W 071° 02.205', the ridge becomes less steep and more rounded, easy to walk on. You reach the pass {11-04} [5.4/2385], and make a sharp left to go along the Argentina border. Go across a few easy snowfields. Amazing views of snow-capped volcanoes all around. Condors swooping near my head. Felt like I was the only human on earth. Still lots of snow on Cerro Dedos. Once GPT11-02 meets with GPT12, you pick up a faint path and navigation is easier.

Season 2021/22

  • 2022-Feb-25 / 3 days / Hiking / NOBO / RR / Romain

- If you cook on campfire or on wood burning stove you have better stay discrete because everything burnt some years ago and the landscapes are still marked.

- There are a lot of Araucaria trees. You can easily save food just by harvesting piñones on the floor following the path. I would recommend to not rely on it because it depends on the period, but there was plenty.

- Camp {11} [22.6/1461] : I loved this place. It was very comfortable with grass on the soil, almost flat, protected from the wind even if there is some in the valley, discrete, and I spent much time looking at the stars thanks to a good and warm (or at least not cold as it was the previous days) weather. To get water you have to walk 3 minutes following the point on the GPS which is precise

- Ford {11} [18.0/1199] : I had good time there, the weather was very good, the place is calm and good to rest, water is still cold but there is enough to wash if you want to

- From GPT-11C Start to Guallali it's now a Minor Road so it's very easy to follow and you meet a lot cars going in both directions, they just waved me.


  • 2022-Feb-13 to 2022-Feb-14 / 2 days / Hiking / SOBO / RR + OH 11-01 (ABCDE) from the pass to Termas Pelehue on GPT12 / Veronika & Jo

The MR out of Guallalí continues until about km 12 on RR-TL-V (another trail that's been jeep-tracked recently) where it veers off to the north. We found out two kilometers too late, but got back to optional route 11-C by CCing through some araucaria forest. This turned out to be a happy little accident, as, this way, we saw a family collecting things from the ground, which turned out to be piñones. Here is where we learned that the ripe cones are "café", and that the piñones just fall down when the cone is hit with a stick or a rock. It's basically nature's piñata (no etymological relation though!). Before getting back to the track, we found some low-hanging ripe cones, which sprinkled more piñones than we wished to carry. Got a nice free meal out of those we did pick up :)

Camped in one of the many camp sites deeper in the mountains.

The next day, we decided to skip the descent to Ranquil after the pass, instead taking the optional route 11-01 (ABCDE). 11-01 stays above 2000m on the slopes of the peaks to get to Termas de Pelehue on GPT12. We had food for three more days and the weather was excellent.

We regretted this decision. 11-01 is CC without a clear path. Initially you're walking diagonally on a 45° incline of scree and sand, which is technical and requires constant concentration to find the scree-free spots. Later on, you're going from lower-incline slope to slope with little high-incline "gulleys" in between (as usual on a mountain flank). At some point, we did not see how to cross such a gulley at the spot suggested by the track files. We decided to descend to the point where the gulley seemed to have a passable incline, to ascend back on the next slope. This turned out to be a mistake, as the slope became more inclined before the gulley became passable. In the end, we did a lot of clambering, I got some fresh cuts from sliding down high-incline scree, and we narrowly avoided some scary looking cliff edges at the low end of our slope. This was the most dangerous situation we got in so far, and we were not really prepared to handle it well.

I'm not blaming the track files: it was clear that it was high-altitude CC, and there was a waypoint warning of "demanding clambering" (though it should not be limited to "nobo"). Maybe going up the problematic slope instead of down would have been the better decision. Just be aware of the challenges this optional route brings. Definitely not doable in bad weather (you would just slide down to your death in some spots). Note that OSM shows a trail a little to the west (a little lower on the slopes) of 11-01, which connects at the beginning and end. We think we saw this path at some points during our traverse. This may be the easier route to follow instead of sticking to the CC points (which was the superior strategy on all other CC sections so far ;) There's a water spring at S 38° 06.178', W 071° 04.579'.

Anyway, we were happy to reach the Termas de Pelehue. Sub-par hot spring, but great scenery all around. You can camp there, we went for a small spot protected on most sides by mountain slopes: S 38° 07.407', W 071° 03.775'. There are some non-sulfur water springs as well as a warm river to wash up in the surroundings.

We continued on GPT12 for one day, getting back to Ranquil via the southern optional route 12-01. This way, we could catch the bus to Lonquimay the morning after (left at 07:55, there's a second one at ~17:00 Mo-We-Fr). Camped opposite the carabineros (on their suggestion) a bit behind the bus stop, close to the river.


  • 2022-Jan-17 / 2 days / Hiking / NOBO / RR / Molly and Melissa

We arrived in Ranquil with the bus at 17, and walked about two hours to the hot springs where we camped. They are not very deep, but you can probably lie in them comfortably. Nicely warm. The ascent towards the pass next to Cerro Moncol follows the riverbed, and as previously noted, it's necessary to cross it multiple times. We were able to cross without getting our feet wet every time, though. The terrain before the pass is difficult, but after it immediately gets easier and the trail is easy to find. We were in a snowstorm and found it easily. The trail to Guallalí is pretty easy, a long way before Guallalí it becomes a gravel road.

As described by others, there is a shop in Guallalí with VERY limited supply. It's next to the brown house of big planks, but you enter in front of the little red house to the right. Romina normally still offers accomodation, but when we were there she was leaving for an appointment in the evening and couldn't have us. She pointed us to the carabineros to camp, but they didn't want us there and told us to go to the camping ground "3 km" down the road. It turned out to be more like 12, and we ended up camping on a field some km from Guallalí


  • 2021-Dec-03/ 1.5 days / Hiking / NOBO / RR / Marc Anthony

Took the bus from Lonquimay to Ranquil friday at 15:00 (leaves Monday, Wednesday and Friday). On arrival I met two fellow GPT-hikers. Started off in some pretty bad weather with hail and thunder, but it luckily passed after a few hours. The first challenge I encountered was walking up the small river towards the first mountain pass (NoBo). To make my way up this section I had to cross the river countless times because of the difficult terrain by the river banks. Getting wet feet was inevitable. Afterwards I encountered a snowfield that leads up to the pass. Definitely possible to avoid the snow by walking along the edge, but I found it easier to just make my way up through the snowfield. Continued on to guallalí where there is a mini-shop with very limited supplies. (There are no flags or signs that indicate there’s a shop but it’s by the brown house made of rustic wooden planks.) Went directly on to GPT10 and made camp at the camping ground by el barco lake (5000 pesos) you can ask them to charge your electronics by the house where you pay. They didn’t sell any food.


  • 2021-Dec / Hiking / NOBO / OH 5 / Franck & Damien

Be aware there are only 2 water spots on the road around the volcano One at the start (tap by the conaf barrack) and a very small one at the camp before entering the scoria field (not sure if water flows after december). Make sure you load liters of water, esp. in summer (heat + exposure to sun) Plenty of water (snow melt) once you passed the volcanoe. The TL from Contracto bridge to Communidad Chenqueco is now a kind of MR, we crossed several 4WD there (? !!). There is plenty of water there.

Season 2020/21

Season 2019/20

  • 2020-Jan-28 / 4 days / Hiking / SOBO / OH5 / Martin

4 days. 120 km. Because of bad weather forecast in the high parts of the cordillera, with strong winds, rain and even snow, we opted to take Alternative route 5 from Chenqueco to Lonquimay Volcanoe. A lot of road walking at the begining but the scenery and trail in the National Park were really amazing and worth it. Beware that in the traverse through the volcanoe to Corralco Ski Resort, there is no water and also difficult to camp. High winds and a lot of rain at the end. We checked many hostels in Lonquimay and the most convenient for us, was Hostal Nativo close to the main square.


  • 2020-Jan-23 / 2 days / Hiking / SOBO / RR (mostly) / Frank

2 days & continued to GPT12 At Pass 2180 wind & rain came in, I diverted onto OH-CC-A@11-03-#001 as described by Linda. Snowfields were old & undercut by stream leaving tunnels 5M deep, definitely not safe to slide on. Walked on edge of snowfields or a little above them on right. Then you enter a gorge, it is best to stay close to the stream & only leave the gorge if you must. In to Ranquil, nothing there apart from Carabineros & no traffic. From Ranquil I continued on OH-TL-V@12-01-#001 to GPT12


  • 2020-Jan-23 / Hiking / SOBO / RR / Ty & America

Guayali - Termas de Pelehue Short & Beautiful. 4:00 Bus Ralco - Guallali. Arrived at carabineros after 8. Luckily they let us camp outside. TONS OF FLIES, so be ready for that. The thermal pools at Pelehue are up by the fumarole. The traverse over there is gnarly, steep, slippery, all the good stuff. Quite small, but with an AMAZING view. The lower one seemed fine to get in, we didn’t as we wanted to make it to the next hot springs on section 12.


  • 2020-Jan-17 / 2.5 days / Hiking / SOBO / RR / Martina & Ivo

Start: Guallalí, End: Termas de Pelehue 2.5 days. We went from Ralco to Guallalí by Fletes (see section "To section start"). It's a bit expensive but we didn't want to take the bus at 16:30, arriving late. Beautiful section. The first hot springs are worth the detour if you have time to clean them and dig a bigger pot (would take you approx. 2h), otherwise you just have a warm foot bath. After the pass we took the optional route #002 leading back to the regular route, then we switched some times between optional and regular route and finally took the optional route directly to the Termas de Pelehue. This part is quite demanding as there are some landslides where you have to find your way through somehow. The hot springs are gone due to lack of maintenance.


  • 2020-Jan-15 / 3 days / Hiking / SOBO / OH 5 / Maddie & Tom

3 days, 120km walking around Volcán Lonquimay. Given section 11 was not feasible due to high levels of snow we took Optional Route 5. For us it was 5 star scenery. It is beautiful and the trail is very easy to follow with trail markings in the CONAF park. We found it to be quite a quick section as a result of the easy navigation and good trail quality. Good resupply options in Lonquimay (we stocked up on food as well as bought some new socks and more 95% alcohol for our stove).


  • 2020-Jan-09 / 5 days (GPT11+12) / Hiking / SOBO / OH / Matus & Anna

We combined sections 11 and 12. It took us 5 days including one zero because of weather. Patagonia showed us bit of it's potential in these two sections. All walked trails were in good condition and CC sections pretty easy to navigate. In the sadle of section 11, because of strong wind, poor visibility and fresh snow and ice we were forced to take optional to the valley. There is a big snowfield, I don't recomend sliding on it all the way. It the lower parts there were big holes into the stream. From Ranquil we took optional #002 because we didn't want to climb back up. Uphill is more a minor road, downhill nice trail. After a laguna we took a optional to the Pass 2180 and road around the Pehuenche Extortioner. We needed to get down from elevation ASAP bacause of wind. We passed puesto early in the morning and no one was around. After rainy day everything above 2000m was white. We took trail to pass 1920m which was just with bit of fresh snow and then took minor road #001 down to valley. So I have no idea about the rest of the trail. Edit: adding a picture from the last sadle 1920m, we did after "rainy" day.


  • 2019-Dec-27 to 2019-Dec-28 / 2 days / Hiking / SOBO / RR + OH 3 / Linda

Regular hiking route until the pass 2180 meters and then Option 3 Nice section ! After the pass, I decided to go down along Option 3 that goes into the canyon. Lot of snow at the beginning, but that was fun cause the slope was not very steep and I could use my bag raincover as a sledge to go down! Then, I ended up into the canyon, crossing the river at least 20 times but no problem cause the water level is low and the river is tight (compared to GPT07 for instance). The only difficulty was once the canyon becomes too tight and I had to find a way up and had to face a landslide. Just one part of 5 meters wide but quite dangerous cause very sleepy with the rocks falling down. After, back into the canyon until I could join the Regular Hiking route. No difficulties until Ranquil. Was lucky to find people with a car who dropped me in Lonquimai cause I had to resupply. Otherwise, only 3 Buses a week from Ranquil (no tiendas to resupply) to Lonquimai = Monday, Wednesday, Friday Supermercado with everything to resupply and accommodations in Lonquimai


  • 2019-Dec-12 / 4.5 days / Hiking / NOBO / RR / Sophie & Hendrik

In total we were 5.5 days on the trail, of which we spend 1 in the tent due to bad weather. On Cerro Moncol there was still some snow, which made us very slow, as we either had the options to walk on steep snow or walk higher up in more difficult terrain. Rivercrossings were no problem. We liked: The amazing views, the condors we met at the northern part of the pass (they came very close to us), the mountain crystals of which there are plenty on the northern side of Cerro Moncol. We did not like so much: The higher difficulty due to the snow in some parts (Snow on top of Cerro Moncol made the regular route more difficult)
