Cambios

TL/DR: A beautiful but exhausting section.Reserva Nacional Ñubles is officially closed, but they are still letting people in. If taking Opt 3, look for the trail that starts just after El Trumao heading NE for a more interesting hike. Los Peucos is open, but has no food or power so not currently a resupply option.

We took the bus from Chillan to Recinto hoping to camp for the night and take the early bus up to Termas de Chillán to begin the hike. (The bus that goes all the way to the hotel only goes twice a day. Both leave from the Terminal Rural in Chillan one at 08:00, the second at 14:00.) There were no camping options in Recinto, so we walked to Los Lleuques. We found a hostel called Antupiren at the entrance of town. 13.000 pp for private with shared bathroom, very nice owners. They have a restaurant too. There were some other places with signs for hostal and campamento further down the street. There are 4 or 5 shops and grocery stores in town. If you stay in Lleuques, a little further on is a nice public access beach along the river called La Playita that is popular with locals and a good place to escape the heat for the afternoon.

We got up early and were at the bus stop at 08:15. The bus arrived at around 09:30. It only goes as far as the hotel and then you have to walk about 1 km up to the ski center where the trail begins. The beginning of the trail was steep and dusty, then leveled off a bit. It passes by some fumeroles. There are two paths up to the pass. One is not on GPT or OSM at the moment, but it is a marked path that is clearly visible. It goes more to the left and up. The other is a horse trail which is the one GPT goes along. They both meet about half way up. We took the horse trail up. There is some grassy area and access to a stream. Nice views of the valley on the way up. Close to the top there was still a small snow field left and the way around it was walking above it on large, loose rocks. We had resupplied for 8 days and our packs were around 25 kg each. Due to this we felt it would be unsafe for us to try to navigate the section so we decided to walk back. It was disappointing, but we were also thinking about the difficulties others had in crossing Rio Diguillin further on and figured it was an early warning. On the way back we took the marked path which was actually more difficult than the GPT track, which surprised us since it looked more like a tourist trail. We were rewarded at one point however with a spring gushing out of the ground and took the opportunity to get fresh cold water without the need to filter. When we got back to where the fumeroles were, we chatted with some mountain bikes and a couple of hikers. There is another route down which had an OSM track on the map. The bikers explained that it is the route they all take down. It is open to hikers as well and there are signs advising bikers to watch for hikers, but the biker said there are a lot of curves and it is possible to get hit on the way down if you are unlucky. It was around 18:30 and he said they were the last group, so if we just waited for them to leave we should be able to hike down without worrying. We waited, and it was totally worth it. The trail down is very dusty, but with much less incline than the way up, and at a certain point goes through a really beautiful beech forest with lots of wildflowers growing. There is no access to the estero until the bridge at the end. We tried to find a place to camp, but no luck. We ended up walking the highway back to a point where we had seen a dirt road connect to the estero and camped there for the night. Not optimal, but it was already dark by that point, so we were just grateful to sleep.

We walked the highway until the Los Coltrahues nature trail that runs parallel to the highway and then walked that to Las Trancas. It was a pretty path and a nice alternative to the highway. In Las Trancas we bought food for lunch and dinner at a shop next to the bus stop. There are one or two other stores back the direction of Lleuques as well. A micro picked us up and dropped us off at the beginning of Opt 3. We had barely started walking when a family in a truck passed and offered us a ride to the river. We were incredibly grateful as the first 3 km of the road is incredibly dusty and there is actually a lot of traffic moving through. From where they left us we walked to the bridge and down to the river to have lunch and coffee. Lots of families were camping around the area. After lunch we got back on the route. A little further on the road was closed to vehicles due to storm damage and construction adding new culverts. No issues walking it. About 6km from the bridge there is a campground called San Antonio. It was also closed since the road was closed, but it was easy to get into. There are picnic tables and plenty of camping along with river access. We camped two nights to give ourselves a rest day. A few locals passed through, but no one else camped. It was very peaceful except for the tábanos. I killed more than 50 over the course of the day and it didn't seem to make much of a difference.

We got up early to beat the heat and walked the first hour in the dark. We passed the area where the road has collapsed and where they are doing a reroute. No issue to walk it. We arrived at the gate that Lilian mentioned, the one with the dogs, at 08:00. There were 4 dogs that bark a lot. The guard came out, it seemed like we had woken him up. We explained what we were doing and he actually had no problem letting us through, but asked rhetorically what we were going to say to CONAF upstairs. The road up is in good shape. There were a few places to fill water along the way. When we arrived at El Trumao there was a CONAF guard there as well as some other people. He was incredibly nice, just registered us and then told us because the park is officially closed there was no fee to enter. He looked at our route and told us about another option, charged our phones for us, let us take water, and then even walked with us part way. The OSM track that runs along the river is a really nice option and we really enjoyed it. The first part is no longer relevant as the river destroyed part of the road and CONAF had done a reroute. If no one is there to show you, head along the GPT route toward Valle Hermosa until you see a trail branch to the left. It will be very obvious as it has wooden posts painted yellow on top and the whole trail has rocks lining either side. Follow that up. The first part was a lot of up and exposed, but after a while we entered native forest and enjoyed stretches that were in shade. There was a rest area with river access. Just after the waterfall lookout the trail dropped down a bit into a grove of old oak trees that was really nice and we camped there for the night (-36.95540, -71.45022) River access was about 100 m further on. This is a really great route option. It is along a trail instead of a road, it drops into RR about 18 km further north than finishing Opt 3 as marked, if you want to go to Los Peucos, you don't need to back track, and it stays on the south side of Rio Diguillin, connecting with RR just after the ford point others had trouble with this season. (Jan, if you read this, we enthusiastically endorse this as a variant for Opt 3!).

The pass was a little overgrown, but nothing too challenging. On the way up we passed through a beautiful forest. We stopped at the last marked water point on the way up for a snack and coffee. The way down was dusty and then it opened up into a plain. The plain was easy, but as we went around the corner it turned into a swamp. The GPT route avoids the worst of it, but careful foot choice is important in some places. It was also really hot and humid. Then it was up again and then down again to get to Los Peucos. We initially followed RR, but the ford point looked challenging and there was barbed wire on the other side. I went across without my pack to try to find a way up. The rocks in the river were really slippery and I feel in at one point, but no injury. On the other side I climbed under the wire and up a hill. Then I had to climb under more barbed wire. I walked onto the property and ran into Ricardo who manages Los Peucos. He was very nice, and took me to show me the front entrance and a much easier ford point that is defined for cars to pass, which turned out to be Var B. So if going to Los Peucos SOBO, I recommend taking Var B. I went back to get Kasia and my pack and we camped there for two nights in order to clean out gear and take a rest day.

A few notes on Los Peucos. Los Peucos is open, price this year is 5.000 pp for termales only, 10.000 pp for camping, 24 hours of access to termales and wood to make a fire in a fire pit. They were having trouble with both their generator and solar panels and have been without power for two months, so don't plan to charge anything there. Also a section of the road there was destroyed over the winter, so almost no one is going there and they aren't getting any resupply for their tiendita, so don't plan on this as a resupply point until someone posts that this has changed, which may be awhile since there seems to be some bureaucratic issue preventing the road from being fixed.

We left Los Peucos just as it was getting light. The road and trail are in good condition for walking. We took Var D to cross Rio Polcura. River ford was easy, thigh high but very little current. We stopped at the camp at [72.9/1104] to have lunch. There were some arrieros and Carabineros already camped for the night, and it was too early to stop for the day, so we continued on. The valley path that RR follows is surely more interesting than walking the road along Var E, but it is fairly overgrown with spiky plants and it was slow going. There is almost no river access along the path, but there were one or two streams. We do not recommend the camp at [78.6/1203], especially if you are using a trekking pole supported tent. It is overgrown and difficult to access, anything that is not sand is covered in those annoying plants that leave tiny spiky balls attached to your clothes, and river access is not great. We ended up camping in the old road grade just above, but it was pure dust. We really regretted camping here, however it was late and we didn't know if there would be any place else to camp further on. (There is though!)

We were to tired to do the pass, but we didn't want to stay camped in the same place for the day. We found a better campsite just 2 km further up trail (-37.09454, -71.31211). Just before the trailhead to the pass, on the left side of the road, there is a dirt path going down to a camping area that arrieros use (it is the same road as the end of Opt 1). It has grass and could fit probably two or three tents. The river access is about 100 m away, but it was really clean access with a stone beach and even a small sand beach and a great swimming spot to cool off. There is essentially no shade so it wasn't great for a rest day in that respect, but it was directly below the pass, so a great starting point for that. We took advantage of the river and washed all the dust off the tent. The fabric felt like new afterward!

We got up early to try to tackle the pass before sun hit. The trailhead is a little easier to find now as more arrieros and hikers have gone through. The pass up is overgrown in places, but not as bad as we had expected. There were some great early morning views. Something killed most of the forest in that valley some time ago and all the dead trees are sun bleached white which was really interesting. As Lilian mentioned, there is a place where the trail collapsed. People have been walking about 5 m upstream and crossing there, but the short reroute is eroding and it looked a little sketchy to us. We went into the stream bed and climbed up through the bamboo to regain the trail. It was lovely forest higher up and on the other side for some time. Keep a lookout for a nice view of Laguna del Laja from a distance on the way down. The valley was another world entirely. Completely exposed, mostly dry but with some sections of swamp, we lost the trail a few times in a maze of overgrown thorn bushes. We took an afternoon break at the puesto just before reaching the lake. We were a little underwhelmed by the lake itself, I think because it has no trees around. We got a little lost on the way up to Laguna Roble, but a very friendly and helpful arriero staying at the puesto at the end of the valley saw us and came out to help direct us up. We stopped at the marked campsite at the east side of the lake. Previous entries had suggested the west side campsite is more wind protected. I went packless to scout it, but I could not see any way in and the water access near the site looked like marsh. We stayed on the east side, no wind issue for the night. The water in the lake was not too cold, so nice to swim in.

We started early to get through as much of the pass as possible before the sun hit. The beginning of the trail was actually hard to find, but once we were on it, it was clear. The up was very demanding and exhausting, and it was overgrown in parts. There is a saddle just before the final push to the pass where we stopped to take a break and some pictures (great view of the lake, volcan Antuco and Sierra Velluda) but there were biting ants everywhere that swarmed us and our packs so we moved on. Good views of both valleys as we walked along. Reports from previous years suggested no water between Laguna Roble and Laguna Hermosa. There was at least two water points between, one of which was a very nice spring with shade around (-37.21425, -71.37259). Being exhausted and running low on supplies, we had already decided that Opt 6 would be our exit from GPT08. The route down was steep and thus slow, but clear and easy to follow. There are multiple water points on the way down. We camped about 1 km in at the first marked campsite. There was a shady, somewhat flat, somewhat grassy area that arrieros use for camping and a spring flowing just below. It was a nice spot after hiking so many hours completely exposed in full sun.

The first part of Opt 6 down was really nice. There were nice views of the mountains as the sun came up, then it goes into forest for awhile before the arriero path finally meets the service road. We were also fortunate to have cloud cover for most of the day. There are a few unmarked water points between the last marked one and Rayenco. Rayenco is not a settlement but connected to the power plant. Shortly after Rayenco there is what looks like an abandoned picnic area and sports concha. We stopped for lunch, and it could be used for emergency camping if necessary. Hitchhiking out seems essentially impossible. It's just cars associated with the power plant, and our experience is that those vehicles don't take hitchhikers, probably a company policy. We walked to the highway, chatting with the gate guard on the way out. On the highway it took about half an hour, but finally a kind soul, Sergio, who had actually passed us, turned around and came back just to pick us up and dropped us at Plaza de Armas un Antuco. We found lodging at Cabañas Puelche 2 blocks east of the plaza, 15.000 pp for a private room in the hostel portion of the establishment, shared bath, fridge, pool.
