- 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.

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.
- 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.

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.
Season Section Log
- 2022 Feb: 05-07, SoBo, RR, Kris&Stiina
We continued into this section straight from the previous one - 31H and the start of it, about first 16km, is like the whole previous section - dirt road. We hiked about 5 of those 16km and hitched the rest which I think was possible quite easy because it was weekend and a lot of cars with families were going to the Lago La Paloma.
The interesting part started once we were at the gate after crossing the outflow of Lago Monreal. The big sign was posted there stating that this is not some Sendero de Chile and that passing through here is strictly forbidden. We saw a guy at the gate when we were approaching, but as it was lunch time for us we stayed at the stream. Afterwards the guy was gone and there was no phone signal to call the nr. that Martin Lizondo has provided. After considering options of different routes we decided to keep it cool and climbed over the gate with fingers crossed. There were houses a few hundred meters up the road, but nobody seemed to be at home at that point, perhaps working in the field somewhere in the back, so we walked through the forbidden land without anyone intercepting, luck was with us. A few more gates later we climbed up into the forest and finally the Cerro Castillo National park with a big old welcoming sign. We stayed at the first marked campsite at 22,7km, there is a stream.
Next morning as we were having our breakfast about 30 cows showed up and were completely dazzled by our presence. They stared at us for about 15min until they finally relaxed a bit, but not fully. As we were packing our camp some sudden movement must have scared them and they all went running for their lives as if a Kraken himself was after them, silly cows, we thought. Once we were all packed and ready to go we crossed the stream into the next meadow, and saw all the cows about 200m to our left. I am not exactly sure how cows work, but as soon as they saw us they organized a gang and all of them started running right at us. We of course were standing our ground so the cows would stop just 5m from us and look all tough. I would try to scare them away by counter attack in the form of a shouting, hiking pole waving lunatic. It worked to some extent, as we could slowly walk out of it, but the cows kept persistently be really close and walk/run at us. I guess they were trying to protect their pasture, maybe someone can enlighten me about cow-dynamics.
After the great battle of 2022, we disappeared in the forest and enjoyed the nice forest path while it lasted. Once out of the three line the path disappeared so we more or less followed the GPS marking. Neither of our maps showed the mentioned old path descending down into the valley, it was actually matching with the GPS, more or less. Up to the first pass, which is not marked, but is at about 26,8km the cross country was easy and then as mentioned before it got pretty difficult. If it would just be steep scree slope it would be alright, but this one had hard packed sand under the scree or sometimes no scree on it so it was very slippery (in dry conditions). Lots of prayers went to the Gods of Friction which helped us with traversing the treacherous slopes, with plenty of chances to become a statistic. I don’t think that that traverse is possible in wet conditions, not without crampons. And as for every good cake there is always a cherry on top, which was a little rock climbing session, which I personally didn’t mind, but I am not sure other hikers would appreciate. After that we still had to descend a steep scree down to the river. If there is a potential trail or option to go down the valley after the pass and then follow the river bank up, I think it is definitely a better, faster and safer option, especially if weather is not favorable. And looking from above down the valley it seemed like a feasible option to follow the river as the river itself was easily crossable and we didn’t spot any cliffs there, maybe next time.
After reaching the river at the valley bottom the way up to the second pass was easy and straight forward, even though still “sin sendero”. The way down from the pass is steep and bouldery but not dangerous and after a short bit some first signs of an old trail can be noticed, some cairs appear. Then once the trail gets down to the tree line there are a few bushy places, but nothing too bad and the closer to the actual trail you get the better it becomes. We also somewhat followed the GPS track but stayed more in the forest rather than beach to avoid the ranger hut.
Once we made it to the Las Horquetas trail all our worries were behind us and we could enjoy the nice trail and magnificent views. I don’t think I have ever seen tree line ending almost at the edge of the glacier in Europe it was happening a century ago, pretty cool stuff. We camped at the “segundo camping” with many other hikers, none doing the GPT though. And an interesting thing we observed was that people would just drink straight from the silty glacier stream without filtering or treating their water at all. Observation was made of different groups of people at different campsites. Is that a Chilean thing? Very impressive gut, if they can do it, unless ignorance is a bliss or they knew something that we didn’t.
Nevertheless, two more mountain passes and we were heading down to Villa Cerro Castillo, with crowds of day-hikers that had come up to the Mirador Cerro Castillo. From there we actually didn’t follow the GPS track but headed down straight to the town. The ticket office with the park official is actually around this area: (46º 6.7520' S, 72º 12.0032' W). And the trail leading there is the official trail. The one that seemed on the map like the official, was actually not in use, not sure why. The satellite view on Gaia and info on the maps is somehow outdated. We tried to sneak past the office to avoid all explaining we had to do, but it’s kind of strategically placed so it wasn’t possible and we ended up just talking to the girl that was making sure everyone is checking out of the park. We had to pay 18.000 pesos per person which is the ticket for foreigners that want to go up to the mirador. We didn’t spill the beans about camping in the park and our small backpacks kept the suspicion low, so in the end it all worked out pretty good. From there it is still almost 5km to the town on a very dusty road, but with all the day hikers leaving a hitch was not a problem.
The town is really nice with plenty of shops and accommodations options. The only thing we didn’t manage to find was the threaded gas canister, but we found a few half-empty ones left in the Nordic Patagonia mess tent.

- Section 32, Option 7: Valle Balboa. Southbound. 11 days (including waiting out a snow storm). Party (3): Mum, Sis and I.*
After walking Section 35 we emerged in Cochrane to a world changed by the virus. We retreated to the now unfriendly Chili Chico and caught the ferry across to Ibáñez in the morning. For my mum and sister, getting back to Santiago to catch a flight home had been the priority, but on the way they shifted more to the stance I was taking: what was the point? Get stuck in Australia, or here? Patagonia didn't seem all that bad, and apart from facemasks and hand sanitiser, there were no shortages like back home. By the time we reached Coyhaique we'd all decided to stay a week or so to hatch a plan. We met up with Aldo and camped in his backyard for almost a week. I helped build his house a bit, but time was mostly filled with playing chess, dice, cards and guitar. The atmosphere seemed to encourage a lethargic state, blurring the days together and bending time. Finally however, we packed and walked into the town centre to make a start on the interesting option #007 of Section 32 through Valle Balboa, (traversing roughly from Lago Desierto to Río Ibáñez). With the virus and public transport on hold, it seemed unlikely the bus to Villa Freí (that we took last time for the RR of Section 32) would be running. We asked a taxi driver for a quote to drive us out. We grabbed some more supplies, and then caught a taxi with a much friendlier driver to Lago Elizalde ($15k). The driver showed us a great public camping spot on the shore of the lake. There were many established camp sites back from [close to] the beach. It was such a nice spot that we decided to lay back and spend the afternoon and night there.
In the morning, we walked the road to Río Paloma, scoring a lift for 5ks or so. We camped by the river not far before the end of the road.
In the morning we walked the last bit of the public road to where it ends at the very rickety bridge over Río Mogote. There is a nice little camping spot here (-45.91100, -72.31823). Climbing over the locked gate, we walked the private road to the ford. We tossed up visiting Lago Desierto and the people living next to it, but with the virus decided against it. This meant we didn't actually have to cross the river, instead locating the old road to the south. (The track files follow the road, but it is no longer used by vehicles and it is actually easier to head back down the main road a couple of hundred metres to where a cattle trail exists (-45.91601, -72.30806)).
Following this distinct road for some time, it seemed to be used for horse riding tours as there were coloured signs like "Spanglish" and "Toobooku" on the side. You will soon reach the gate included in the track files. Here there is also access to a bridge across Estero Balboa. It looks like you can then access trails most of the way up to Cerró Negro. This might be interesting if someone wants to explore.
A couple hundred metres after the gate the old road ends and an obvious trail continues to a miskept farmhouse. Continue along the well defined trail that gets a bit scrubby/overgrown before entering the forest. The trail is then very well maintained although quite muddy in spots (I could see it being quite bad after rain). You will need to ford a tributary not marked in the track files (-45.95592, -72.35114). Shortly afterwards is a junction (-45.95654, -72.35216). The route up the side valley could be explored if someone wants - we went only a short way to a corral. The track will dip back down to the river where there is an established camp (-45.97039, -72.35461). Continuing up the valley, there are many more established camps - the best are generally in close proximity to the fords.
The first time you cross the estero is about here: (-45.98105, -72.36205). There is only one ford, not two as the track files indicate. At the next couple of fords, the actual track deviates slightly from the track files. If you follow the current track files, you will avoid crossing the river at all, but will end up bush bashing briefly. We crossed the next two fords, but by staying on the west side of the river they should also be easily avoidable.
The trail exits the forest (-46.02116, -72.42538)(the camp marked in the track files here is a swamp - go further up the valley!) from where it is cross country walking, not actually a trail as indicated. We camped next to the puesto which incorporates some pieces of a crashed plane (we found another piece whist exploring, but not the actual crash site). The route up to the Laguna Campana is also open and straight forward.
We waited out a rainy day only to wake to a snow storm the next!... and the next!. We ended up waiting 4 nights experimenting with some different bread recipes whilst we waited out the inclement weather.
Finally a sunny day! Continue up the valley, CC walking past an old corral. At the Nacimiento del Estero Balboa you again briefly enter the trees. Like the previous marked camp, again this whole area was very swampy and I didn't see a suitable place to camp. The camp included in the track files is in the middle of a swamp! We picked up fragments of a track heading up through the trees, but I think it is very vague or overgrown. That said, we had nearly a foot of snow in places so we could have easily missed things! There is a very obvious section of track here : (-46.05648, -72.47298). You'll quickly exit the trees (-46.05923, -72.47005) and start a long CC section in the alpine. We found some sections of trail, but for us it was mostly cross country walking. Plenty of water options the whole way.
When you enter the forest after completing the alpine section (-46.08687, -72.43537), you will be bush bashing for a long time! There was no discernible track even when we criss-crossed over the track files searching for it (no snow here anymore). Approaching the deep gorge, I decided to lead us a different, less steep way. This worked well and we camped at a very nice spot by the stream at the bottom (-46.09414, -72.42582).
The next day we were debating simply following the river down (I wish we had!). Instead, we headed straight up the other side of the gorge. We located part of an old track here (-46.09685, -72.42463) but quickly lost it as we passed through the saddle (I think maybe it continues north?). Rejoining the suggested investigation route (EXP-OP-TL-I@32-07-#003), there is a good stream (-46.10202, -72.42403) and some camping on its banks.
After some horrible bush bashing, we finally made it to a ravine gashing steeply down the mountain (-46.10598, -72.41534). There were many drops and it was impossible to go directly down. We later found out that the only other party to do this part had a rope! I can't really recommend going down here [and my sister can't recommend it at all! - "This is shit!"] Again, I'd recommend taking the main valley. The climbs we did were much more difficult than those on the northern part of Section 32 RR that people complain about. Also, if doing this option, it would be much easier travelling north! You could also consult the settlers on a better route. We finally reached the bottom where it opens up after about ~6hrs!
Continuing, if you do follow EXP-OP-TL-V@32-07A-#003, the track files indicate there is a trail, but it is not quite so. There are CC sections and a labyrinth of cattle trails. You will need to use them to your advantage where they exist, and leave them when they go the wrong way. We went this way for a little while, but then tried following a primary cattle track that seemed to be heading directly down to the river... but we got stopped by a swamp (-46.11623, -72.41080). Continuing along EXP-OP-TL-V@32-07A-#003, you will get CC walking from the woods (after a cliff) about here: (-46.11546, -72.42372) If we were there again we would follow EXP-OP-CC-A@32-07-#004 down past the settler to the river. It then looked easy to walk along the river north to the cable car.
The cable car: Don't use this by yourself! Don't use it if you are only two! Use it with three people minimum! I can't stress this enough. There is a lot of fiction and the locals we talked to here don't even consider it safe. They used the boat which has its own steel cable allowing you to tack across with relative ease. You will get wet feet if using the boat.
Taking the cable car, we only just made it across with one in the car and two hauling on the rope, and at one point it looked like my sister might get stranded on the far side (she had a nightmare that night!).
Carretera Austral: We waited the entire day by the Carretera Austral. Finally catching a colectivo late in the afternoon. With the virus, it was hard/imposible to hitchhike. We paid an inflated price ($3kpp) for transport to Cerró Castillo.
- 2020-March-6 / Ty & America / 4.5 Days SOBO RR. Start @ El Blanco
We started in El Blanco, opting to hike by Lago Montreal, which was pretty nice. No traffic though, so if you’re wanting a hitch the regular start in Villa freí may be a better option. Settlers in Lago Montreal are super friendly. There’s a bit of water there as you pass by the lake. We camped there. I recommend going further to the marked camp though because the next day is a big challenge. RH-CC-A@32-25.2+7.9 Is the Cruz of the section. After this all good. I do not recommend doing this unless you’re very comfortable on your feet and have a lightweight pack.
-stick to the treeline/marked path on this. The traversing is tough, but completely doable. 2-3 km in is the gully with the very difficult climb. Keep the the grassy patch, getting to the base of it was the most dangerous part for us. Very slippery rock. I had America drop her pack. High risk, but I was MUCH more comfortable.
-about a k after is the second dangerous area. This is a straight rock wall that spans all the way up& down the mountain. The only way through is to climb around. I checked below it and didn’t find a way through the trees. I took both Sanita & America’s packs through this section; as again, it’s very high risk..with an actual climbing move involved. Again, it’s important you’re very comfortable with your pack to get through these parts.
After these dangerous sections we were wiped out and camped in the valley before the pass. Lots of places to camp with good water. Be aware of slight rockfall risk. There’s an amazing place to camp with ideal conditions at the top of the pass.
Going on, all smooth, both marked camps on the way up the second pass are actually closed...there’s an open camp right between the two.
Amazing places to camp up by Laguna Castillo.
We snuck around the riverbed once we saw the blue tent at the bottom (where you might have to pay) and got by with no problems.

days / Northbound / Regular Hiking Route with OH-MR-V (Villa Cerro Castillo to Las Horquetas)/ The section follows the rather popular tourist Hiking route Las Horquetas for the first two days, meaning there will be less solitude but also rather well maintained trails. The national park and the region around Cerro Castillo was very impressive, we especially enjoyed to take all the side trails and visit the numerous beautiful glacier lagoons. The only unpleasant part of the hike was the organization of the national park. The exorbitant high entrance fees are in no relation to the other parks, which is due to a high ratio of private land in the area but makes the park rather unattractive for tourists. some rangers seemed poorly informed and couldn't give much information (e.g. insisted that passes were "closed" and only after asking numerous times agreed to check with his colleagues that told that they are "open"). They also said it is not possible to hike the regular route of the GPT, because we have to check out of the NP at the checkpoint Las Horquetas. There is an optional hiking route continuing North from there. Due to bad weather coming up we ended up not finishing the northern stretch of the trail and just followed the entire Las Horquetas Route at the Carretera Austral.
Jan 2020 GPT32 South 7days
_____________________ Coyhaique to Villa Freí: There is a bus from the bus terminal in Coyhaique to Villa Freí. From there it was a hot dusty road.
_____________________ Accessing the park : You have to pass through 4 private properties to enter the first sector of the park. We met some people. Had short friendly chats, but no problems with access. Just before you enter the park (where there are two trail options) there is easy access to the river via a cow trail. However water in general was no issue and I didn't carry water for the entire 7 days through the park.
The camp site used to be an official campsite before the sector was closed due to access problems. The dunny is in great shape.
_____________________ Through the first sector : The trail is in great shape until after the mirador. You then cut upwards into the alpine which is also easy walking. After passing through a saddle, you contour around above the treeline. This is the most difficult part of the section. Quite a bit of step scree traversing. Not for everyone. Once you drop into the valley waking is again easier. There are some occasional cairns that become more and more frequent as you drop into the other valley. As you contour left an intermittent trail is evident. When you enter the lenga forest (-45.97321, -72.10278) there is a great trail down that turns into a road here : (-45.97886, -72.10358) (Jan: maybe you want to update the track files to reflect this?) Then is road walking to join the popular walk.
_____________________ Popular sector of Cerró Castillo : There are some side trips not included in the track files. They're on the map you get. Note that the old Bosque site (-46.06197, -72.16016) and La Tetera (-46.07200, -72.18390) are now closed. You can not camp there. For most people this means camping at the new el Bosque : (-46.06418, -72.16964)(Jan : maybe you want to update the track files?) Get to Laguna Cerró Castillo before 12 to beat the walkers heading up for the day. But this shouldn't be an issue as you need to cross the pass early : an important thing we would have liked to know is that the pass (-46.08030, -72.21103) can be closed in the afternoon due to strong winds. There is literally a ranger there that can turn people around. Not much water over the pass either. And the poza cerca mirador doesn't look welcoming. Carry water here. In the next valley there were more rangers and we saw some people get checked for permits. It's a shame this park is now being comercialalised :(
_____________________ Getting back to Coyhaique : Not much traffic. The last bus heads back at 6pm
_____________________ I'll try upload some map photos and a breakdown of the entrance fees when I get the photos off my camera.

- Route description by Kara Davis after Season 2017/18:
A sandy beach with a visible structure in the grass is the take-out for Lago Elizalde. After exiting, make your way through the farmland until encountering a gravel road that leads past the house at the top of the hill up to Ruta X-686.
Ruta X-686 is a lightly trafficked but well-formed gravel road that is fenced on either side. After crossing the Río Paloma, Ruta X-686 makes a sharp left and begins to climb. 4 km after the sharp left turn, cross a bridge to the left and climb to a wooden gate. If you descend the steep slope to the left of the gate, there is camping under some trees.
The wooden gate marks the beginning of a very long driveway to a house located near the lake. The route takes you along this driveway until a river crossing. After crossing the river, walk northeast along its shore towards the Río Paloma. After reaching the end of the fenceline near the Río Paloma, turn east and walk along the fenceline until reaching Lago Desierto. At the river outlet, there is a nice beach to put in to Lago Desierto.
There is no camping along the shores of Lago Desierto. The take-out is a rocky beach at the base of a bluff. Walk up the bluff and cross country through the farmland to Lago Azul. At the east end of the farm, descend down a road to a rocky beach at the Lago Azul shoreline with a metal structure.
There are a couple of potential camping options along the shoreline of Lago Azul. There are also several residences on the north shore. The take-out is a long rocky beach set before a well manicured forest. On the east end of the land near Lago La Paloma is an expensive looking house surrounded by several other buildings.
There is a 4WD track to the west of the smaller red house located south of the big residence. Ascend the steep climb on a well-formed road that is criss-crossed with several smaller tracks labeled in english with wooden signs. Due to the steep slopes on either side of the cut out road, there is no camping here.
Eventually, the route turns off of the road onto an overgrown 4WD track. Camping off the track is still difficult because of prickly vegetation and steep terrain. This track ends 2.5 km from where the Regular Packrafting Route joins the Regular Hiking Route. From here, the route involves some bushwhacking and following a small trail as it winds in and out of existence. Just before joining with the Regular Hiking Route, the route widens into an old 4WD track that passes some destroyed structures.
The routes join up at a large rock cairn and continues to follow a 4WD track until reaching a large wooden sign with a map of the Reserva Nacional Cerro Castillo. Here there is also a campsite and ranger station. There is a 5.000 CLP fee to enter the reserve.
The route from here is a popular track for backpackers with designated campsites. The trail is well-formed and winds through the forest. When the trail becomes less obvious, the way is shown with yellow markers. In this area there is a designated campsite with a latrine.
At treeline, follow the cairns and rocks painted with white and red stripes through the scree up and over the first pass (approximate elevation 1.450 m). After the steep descent, reenter the trees. There is a campsite, Camping El Bosque, soon after reaching treeline (approximately elevation 940 m) with water and a latrine.
The trail begins to wind up through the forest toward Laguna Castillo. The sights from Laguna Castillo, which is at the base of the pass, are stunning. There are two tracks that climb up to the pass. Make sure to take the path that climbs to the south instead of continuing southeast over the obvious saddle.
The track down to Ruta X-720 is well formed, marked, and popular, but occasionally braided. Follow it until reaching the wooden stile with a rangers hut. From there join Ruta X-720, a dirt road which leads to Highway 7 and Villa Cerro Castillo.
