We really enjoyed this one. It's definitely worth waiting for good weather, not only for safe traverse of the steep part in the northern part of the park and following obstacles that are quite demanding but also for the views that were just incredible.
Starting from Villa Frei in the late afternoon, we made it on that day to the turn before Lago La Paloma, where we camped right behind a fence, before a little river, that you need to cross to follow the RR. There are 2 settlements, but still far enough, so no problem. You have to cross one fence and a gate on the way up. To avoid right-of-way conflict, we followed Cristopher & Anna's advice (thanks guys!) and turned right after the first gate behind the beginning of the optional trail. From there you just need to follow MR, cross a few gates and you will end up on a fenced field with bee hives on one side. Crossing them will take you directly to RR, so no bush-bashing is necessary. From there, the trail is pretty straightforward. We liked the view from Option B viewpoint and in good conditions it must be a perfect spot for camping, definitely doable in one day. The steep traverse didn't feel that dangerous for us, but we had really good conditions. The next obstacle, already described by others, is at the end of the traverse. We followed there a small ridge that will take you to the beginning of the grass parts. It's a little steep, but doable. From there we followed the grass parts, which create almost 'stairs' allowing you to climb up. It's again steep, but you can use your hands to pull yourself up, holding the grass patches. After that is the last challenging part, a rock that you need to climb over. We got there already after sunset and without an option to explore the best and safest way over, we decided to follow the old overgrown trail, that descends down without the need to climb over the rock. It seemed to be hard in the beginning, but after we got through the first few trees (without any leaves, just branches), we found a little strip without them, that takes you all the way down to the river, where we camped. It took us around 15 min to get down, so it might be a good alternative. From there you just need to walk through a little part of the forest and then continue by the river, so you are actually avoiding also the descent down, which some described as challenging as well.
After the first marked pass and descent in rocky terrain, the CC part connects to an old trail, that later becomes a MR. The connection was easy to find by following the GPS. We had no problems passing around the rangers house, again by following the track files, at first through the forest and later around the river. From there the trail connects to the official way which makes navigation easy. We spent the night in the official campsite around 2 km before Laguna Carro Castillo, which is the only one open. There were 5-6 other tents, no ranger. The next day the weather got way way worse, which made us skip the last pass and go down from the laguna via one of the official routes. We met a ranger on the way up, pointing us to the official trail around yellow cairns, to sign off from the park. With no intention to pay on our way from the park, we actually followed some old trail (according to the old signs we met) that took us to the main road, right in front of the bridge. We had to cross one fence, but no other problem. It's a faster and safe way from the park.

Coyhaique - Villa Cerro Castillo
We hitchhiked from Coyhaique to Lago Paloma and started walking around 13:30 pm following the main path.
The trail at the beginning is pretty good. At the junction with the option at km 17,5 you can walk further uphill along the fence for a couple of meters to enter the fence through a gate. This option is not in the gpx files. We decided to follow that to avoid the settlers after all.Then you can follow the dirtroad through two more gates until you reach a fence that you have to jump to the right to get to a meadow with beehives. There is another gate there and then you reach the main route again. In total we only had to jump two fences.
Then we followed the main route. Soon after we went through the gate of the National park Cerro Castillo and we (unfortunately) met two guardians of the park. After some back and forth they made us turn around, telling us that this path is closed and we have to enter the park via the main entrance and pay the 30.000 clp. So we had to take the option to las Horquetas.
After a few good km on a dirtroad, the path of option 1 gets bad. It seems like it hasn't been used for a long time. It was often hard to find and involved some bushbashing. It took us quite some time to get through there. Once you are at the river it gets much better. We forded the river next to the entrance to avoid the detour until Horquetas. The option was not very nice. Mostly just walking in the forest with BB so we would definetly recommend to try the main route.
The entrance closes at 2 pm but the guards there were much nicer than the first two, and it was also no problem to get in at 3 pm. We had to register us and pay the 30.000 clp p.p. though. The rest of the trek we were not asked to show the tickets. The park guardians tell you that there is no water crossing both passes and you have to carry it from the official camps, which is simply not true. There is only no water after Laguna Castillo.
At the exit (following the RR) we had to register us again. From there we planned to hitchhike to Villa Cerro Castillo, but there were no cars passing by. In the afternoon/evening it's probably easier to get a ride, because lots of cars parked at the exit. We would recommend Option E to avoid the dull roadwalk to Villa Cerro Castillo.
We stayed at Camping El Rincon, which was only 4.000 clp p.p., with no electricity, but the owner washed our clothes after we asked and we received it dry the next morning :)
5 to 7 of February 2023 / Will / SOBO / 3 days Amazing section! I was worried about the tricky part, but sticking to the gpx track it didn't feel dangerous to me. Though I did have to leave the track to find easier ways around the cliffs.
There weren't any buses south out of Coyhaique on Sunday (except maybe early morning?). I ended up taking an Uber to villa frei, for a bearable 14000 pesos. The road walk was beautiful except for the wind trying to blow me into the cars. I caught a ride to Lago Monreal, from where I walked back up to variant L and then to the 23.6 campsite.
I didn't have any right of way trouble, I just had to pass through a few unlocked gates with no people or buildings in sight. There were even a few groups of day hikers who passed by my camp on the way to the Lago Paloma mirador (variant B - must see!).
I also took variant D up to the glacier lake, worth it if it fits your schedule. I didn't have time to keep going up to the glacier itself, it looked like steeper rocky cross country.
Even in the touristy parts the trail was surprisingly slow and rocky. I ran into a few rangers, who look like normal hikers except with red and white baseball hats. They were ok with me not having a ticket once I explained my weird route.
18 to 21 of January 2023 / Véronica / GPT32 RR SOBO / 3.5 days Route: Villa Freí - Lago La Paloma - north part of Parque Nacional Cerro Castillo - Las Horquetas trail (south part of Parque Nacional Cerro Castillo) - Villa Cerro Castillo
First off I want to say that I think this section deserves a 5 on the Attractiveness Scale. It is simply mind-blowingly beautiful and definitely on par with other sections further north that have a 5 on this scale. I also think the Difficulty Rating should be upped to a 5 as well, due to the technical, and arguably dangerous at times, section in the northern part of the park on the Regular Route. Wish I had someone with me during this stretch, but oh well, such is life.
I was lucky and caught a hitch most of the way to Lago La Paloma on the first day. It was hot and I don't think the road walk has any water sources until you get to the end. I then followed the new RR which bypasses the problematic right-of-way settler in the Lago Monreal area. However, this new detour is not fun. It involves climbing over (or crawling through/under) multiple barbed wire fences. I lost count after the 5th or 6th one. Also, the path and cross-country area are full of thorny plants, they got everywhere on my pack and clothing. I think it would just be better to take Option 32-L and chat with the settler instead to try and get through. Once you reach RH-MR-V {32} [18.9+4.7], it's all good, easy walking until the camp at 23.6 km.
I reccomend taking Option 32-A after the campsite instead of the CC straight through the cow pasture. It is wet and muddy, whereas 32-A remains dry and easy to follow in the forest at the edge of the meadow. I also strongly recommend taking the short detour to the mirador at the end of Option 32-B. The views there of the cliffs and mountains surrounding Lago La Paloma are incredible. You could even camp there if you brought sufficient water and the weather is calm.
Now for the difficult part in the 8-km cross-country section. This section was physically, mentally, and emotionally demanding. The first pass is at S 45° 55.740', W 072° 04.501'. It is easy walking up past the treeline into the alpine up to this point. The first challenge is a steep and unstable scree traverse, which begins at S 45° 56.019', W 072° 04.567'. Follow the GPS tracks here. At first I tried to go lower, right along the treeline, which was a big mistake that got me stuck in a terrible gully of slippery hard-packed sand. Very treacherous and scary trying to traverse it on all fours. After that ordeal, I scrambled back up to the altitude of the GPS tracks. This first scree traverse lasts about a km, the rocks are loose and it is very steep. I was tense and went very slowly. Got harassed by tábanos the whole way, but at least the weather was good.
Then at S 45° 56.288', W 072° 05.184', you reach the end of the bad scree and end up in a deep gully with a vertical wall face on the other side. Figuring out how to get up that cliff was hard for me. I left my pack at the bottom and tried climbing up various different ways with no success, only tiring myself out and getting myself in precarious situations where I could barely climb back down. I finally figured out the best way was to try and get to the lowest grassy patch to the left of the vertical rock wall. The easiest way to reach that grassy patch was to go upstream a bit, then traverse on the hard slippery sand northward, instead of trying to climb vertically straight up to it. Once you reach the grass, you can use the traction and stability of vegetation to clamber up and out of the gully.
The next big obstacle is at S 45° 56.320', W 072° 05.446'. Like others have written, this is the vertical rock wall that spans up and down the mountain and that you have to climb over. I scouted ways up without my pack at first, trying to find the easiest way. At least with this rock wall, the handholds and footholds are solid — no slippery gravel/sand/scree. But it does require actual rock climbing moves. If you fall you would likely tumble down the mountain, so please be very careful. A light backpack makes it relatively safer and easier.
On the other side of this wall, you can finally see where the trees end, and the lovely river you are supposed to climb down to reach. But there is still more scree to traverse here, and it is slow and unstable again. I tried taking a shortcut down a shallow gully filled with grass. I figured it would be safer than the rocks, but it was very steep and got unexpectedly muddy at one point, and I ended up slipping and sliding down the mountainside about 10 meters before being able to stop myself. Didn't get seriously hurt, just bruised up, but it really shook me and just added to the stress and fear of this whole section. So I guess my advice here is to again follow the GPS tracks across the scree and go down gradually to the river instead of trying to go straight down.
Once you reach the riverbed, it is easy walking to the top of the pass, with occasional cairns (and some good swimming holes). Down the south side of the pass, there are still a couple scree sections, but not nearly as bad as before. Lots of boulders, so slow going, but at least they felt more solid.
As Martin Lizondo has written, finding the start of RH-MR-V {32} [34.1+1.7] is tricky. It is not a minor road, it is an old footpath. The cross-country section ends at a creek as it turns into a high and steep waterfall. You have to cross the creek and look up to find a faint, overgrown trail that goes up into the forest. Once you find it though, it is simple enough to follow. There is a stretch though of several hundred meters where it is more of a bushwhack than anything else, nature has taken over.
I followed the regular route that cuts through the forest to Río Turbío, I assume this is to avoid the ranger station nearby. The "bushbashing" section is easy through a mature forest, and then you just follow the bouldery riverbank.
Once you get to the popular Las Horquetas trail, everything is easy until the end of the section. Some snow at the top of the first pass (Paso Peñón), but very manageable. The views of the saw-toothed mountains, lakes, and glaciers are spectacular. Despite reports of the park being "overrun," I only met a handful of other hikers in this trail, and most of them after Laguna Castillo. No rangers at all.
I think the Regular Route in its current configuration avoids the blue payment tent at the end of the park trail, but I didn't know that when I passed through, and ended up just following the riverbank down to the minor road to be safe (and avoid paying the ridiculous 30,000 clp access fee). The road walk to Cerro Castillo was Easy and uneventful.
- 23/02/2023 - 25/02/2023 / RR SOBO / Louis, Rémi & Noé :
We started at Lago La Paloma, taking the bus from Coyhaique to Villa Frei (leaves at 8:15,15:30,17:30&19:30 from monday to friday and at 8:00 and 14:00 on saturday (no bus on sunday)). Then we hitchiked to the lake without problem and we camped there. Ready to start in the morning the next day.
Day 1 - Campamento Rio Turbio - 26.5km - +1800m/-1200m A big day but we hadnt the choice : heavy rain was announced for the next day... Cross country is demanding, better follow the tracks all the way long. A great camp site if you want to split this day is at the end of Option B. No water, windy but incredible view. The waypoint camp before is nice too.
Day 2 - Campamento El Bosque - 10km - +800m/-800m The 2 camps sites on the GPT at47.8 and at 50.3 are now forbidden. The new campsite is approx at km 49, in the middle. There is guardaparques, but no need to show the permit for us.
Day 3 - Cerro Castillo - 11km - +800m/-1500m The pass after Cerro Castillo was closed due to the wind. If you want to go to the other side, you have to get down at the park entrance and to go up again at the other entrance. We just went to the town. The regular route going down from there, from the Cerro Castillo, is not the one on the GPT. Actually, it goes more on the west side. At the end, there is a guardaparque, we checked out (even though we didn’t checked in) but no need to pay. Fortunately. Luck was with us.
- 23/02/2023 - 25/02/2023 / RR NOBO / Jakub+Veronika:
1) Lago La Paloma, right of way conflict on RH (32, km 17.5): Owner of the land (and nearby houses) is called Cesar, according to him, the right way is by the mud road (OH 32-L) and not on the trail, which passes some 20m next to his house. The reason why there was a conflict might have been caused by Cesar's relative who didn't like tourists walking on their land. 2) Trail has been changed 3 years ago because of right of way conflict between CONAF and private owners on the OH (32-E). The new official trail (with official park entrance) leads on OH (32-E) for the first 2km, then turns right and goes down towards Rio Ibáñez to RR (32, km 85), well marked by metal yellow triangles.
We've walked all section 32 from Villa Frei to Villa Cerro Castillo. The part from Lago Paloma to Rio Turbio is very difficult and might be even dangerous (especially in bad weather). The CC travers on the stones (in our case with strong wind and snow) was the hardest part. The MR leading down to the valley is partially overgrown. The second part is well marked with good camping possibilities. After heavy rains on Sunday 25th, the park has been closed for more than a week. There are 2 alerts on the road (see above).

Walked from Villa Frei. After about 12KM there is a food truck next to the road. Owners live there so should open for you. The owner of the private land wasn't there so had no access issues. You can camp in a big meadow @ 1250 metres or in good weather at a pass @ about 1325 metres (not marked on track file) just before the difficult CC section begins. Followed Veronica's advice to get up the gully on grass which worked well, thanks Veronica. There is no need for any rock climbing on this route. After the gully there are two rock bands running perpendicular to the route. You can go below both of them & bypass them at treeline. The second bypass is not very obvious but stay at the treeline & you will get through easily. After the pass, descending scree you come to a waterfall. Go left into the forest immediately before the waterfall - you may see a small cairn marking the spot. Just footprints at first but pick up a small trail as you go in. Leaving the park the RR to the left goes through private land. The optional route straight down is now the main trail, it goes down to a checkpoint just before the road. Checkpoint is at a stile over a fence so can't be avoided. It is run as a private 'concession' from CONAF. The workers were friendly & didn't charge me anything. However next year the concession will be run by a different company so depends who is there.

- 2020-Jan-18 and 19 / Regular Hiking Southbound / Martin Lizondo
The starting minor road gets into the private propiety of Pedro Sangüesa (+56 9 9099 9083) at 45º 52' 15,55" S, 72º 2' 46,28" O. He didn’t like people to pass through and denied that there was a trail, but it turned out to be a Conaf’s well signed area. He said in the future he will ask for money, but finally left me pass for no charge. I met other day hikers going to « El Mirador ». Snow was easy at the passes. The trail was in good conditions until the cross country. There are two spots which I consider dangerous, so I don’t recomend doing this section alone: 1) the gps tracks passes through a very vertical rocky (nearly climbing). I was scared and I can’t recommend doing it, except you asume this risk. I could see later in a map that the original route went all way down in the valley through lenga forest, but if there was a trail it’s invisible now. 2) When the cross country leaves the tree line and becomes a small trail into the lenga forest at 45º 58' 23,54" S, 72º 6' 10,02" O (“minor road” starts later, despite the gps track info); it’s very stepy and unmaintained. I made a mistake and started to follow the stream all way down, but you have to look up and search the beginning of the hidden path. It’s very vertical and easy to fell down, because of recent land slides. Be extremely carefull. The rest of Cerro Castillo from Las Horquetas is well maintained, beautifull and enjoyable. Cons: Lots of people. When leaving at the Nezoelandes entrance, you’ll have to pass near to the payment cabin. I didn’ t have to pay, but it was because I spent only a short time in the park. The cost for foreigners is normaly CLP 29,000.

No technical difficulties in the park, just following the trail and enjoying the views.
To follow the GPT northbound, leave the parc trail to go north. It is an "old sendero" in the forest, but well maintained and easy to follow during the beginning (it is marked on maps of the parc). In this direction, no problem to leave the forest in a safe spot, but southbound, looking behind, seemed hard to find the entrance of the forest and of the safe trail ! No technical difficulties until the first pass, rocky terrain like the rest of the park.
The dangerous part is indeed between the 2 passes. You dont go in the valley in front of you but follow the altitude line until the pass that you see at the right side of the valley. Very steepy rolling stones path. I was a little bit afraid. I tried to be smarter than the tracks, trying more uphill... this was a dangerous mistake that took me long to repair and go back to the tracks. There are indeed two river crossing (no dangerous waterstream) but they are circled by cliffs, so not easily crossable. The track follow mostly the tree line (I.e the separations between the little trees and the stones) So my recommendations : - follow the gps tracks : they follow the tree line who is safer with a solid ground and grass. Sometimes you have to cross the stones, no choice, so go slowly, choose your paces wisely and it's doable. Try to aim for the grounds of grass in the middle, which are solid, or the stones with foam on them, which mostly didn't move for a while. For the rivercrossing, it aims a good spot with no need to climb down or up. - choose a good weather day : for me it was sunny and no wind, so perfect day, and it was already mentally hard (not speaking of the horseflies getting you crazy during the hard moments !). I wouldn't try it with rain or big wind in this river of rolling stones. - if you don't feel it, easy escape by the normal trail of the parc
However, I can assure that the prize for the effort, going northbound, is amazing !! But I won't spoil ! After the second pass, no technical difficulties, you find a Conaf trail easily, and I even cross some tourists with a guide.

Snow line is at around 1200 Meters but all passes are safely traversable. The National Park Entrance Fee got raised to 29000 CLP per person for overnight hikes in season 19/20. The park generally seemed very poorly organized, we were told the passes are "closed" at first, whereas they were easy and safe to traverse. The ranger insisted that we could not hike the normal route northbound but have to sign out of the park at the Las Horquetas checkpoint. In high season, the ranger station in the park is manned, so maybe it is possible so sign out there and head northbound.
- 2019-Nov-12 / Eva Havlová
There is still lots of snow in the National Park. I arrived to Villa Cerro Castillo 3 days ago (Novembre 12, 2019) and planed to hike nortbound but rangers didn't let me go. I saw the pass they were talking about (avalanche risk) and I don't think any avalanche could occure, but the thuth is that there is lots of water runing down and the trail is like a stream. They said it might be possible to do it next week.

- 2019 Jan/ OIlrik / Northbound
We ended up doing the normal Cerro Castillo hike as the weather was forecasting heavy rain and snow so we did not want to be on the pass. The regular trail is just gorgeous and the park is beautiful. The trail in the north is not on the new CONAF maps but is marked on the old ones.
