Day 1: RR [0.0-21.2]
Good trail. Only the last 2 km was hiking on loose scree and took some time. Camp Rio Tunnel at km 21.2 has only spots for about three tents. The wind protection isn't as good as at camp Toro (16.6). The river at km 18.9 was a easy ford (knee high) about 50-100 meter up stream of the zip-line.
Day 2: RR [21.2-45.1]
Paso de viento (km 24.0) was very icy on top and on the way down. I managed without spikes, but they would have been helpfull. The pass at km 38.5 was snow free. The trail down after the pass is very steep. Would be very hard if snowy or muddy. Camped at -49.475284, -72.943223.
Day 3: RR [45.1-64.9]
The RR branches off the official Huemul Track at km 46.7. The RR runs a little higher and therefore offers maybe a bit better views. But the official Huemul Track would be the faster option. Rio Tunel was easily fordable (knee high) just under the zipline at km 54.0.

Day 1 el chalten - Rio Tunel camp
The park rangers were closed for strike action. We weren't able to register online either (bad internet connection). We left around 9am. Several people and a group on the first part, but we lost them on our way around the glacier. Magnificent walk between forests, viewpoints and lakes. We arrived for lunch at laguna o toro. Possible bivouac spot with emergency shelter if needed. It's a beautiful spot, but we didn't feel like pitching our tent there. So we decided to head for the Rio Tunel campside. Passing the zipline, in fact the river is probably passable on foot a little above. We recommend that you look at tutorials on how to use the equipment, which we hadn't done, and the rental company gave us bad advice. Fortunately, there was an experienced hiker who helped us. The passage along and on the glacier is complicated. We lost the trail and took a long time to make headway. There are lots of slippery spots (ice), so you have to be careful. Once we'd found our way back, we were able to reach the camp. It's well sheltered from the weather with a few spots (in fact only 3). The place is very windy, so I'd recommend getting there early if it's busy to get a sheltered spot. Magnificent view of the glacier. There are mice, and we saw several in the evening, but we weren't bothered during the night. Difficult to find a place to hang the food so we kept it with us in the tent enclosed and in the middle of the two of us and not at the ends. That's how it was. Several water spots along the way all day (several rivers).
Day 2 Rio Tunel camp - Bahia de los tempanosb camp (-49,47994,-7298601)
Passage of the paso del viento, which was indeed very windy, but passable. The path is still passable as used. Easy to follow. Magnificent panoramic view of the glacier at the top. You can see that some people have already pitched their tents at the pass, but I wouldn't recommend it because of the strong wind. Beautiful descent to the refuge. Very good, in good condition. Lots of possibilities for pitching tents around the stone walls. Very nice place to sleep. We continued on. Passage over Col Huelmul easier than the previous one. Very windy too, but the wind was in our favor and helped us make our way up. The descent is very complicated indeed, and quite dangerous. Take your time, especially if it's been raining. It takes time. Fortunately, there are ropes to hold on to. We reach the camp just before dark. It's very crowded, but we find a place to pitch our tent. The view of the lake, icebergs and glacier is magnificent. However, we were bothered by mice all night. We had hung our food from the trees, but despite this, they came up to the tent (between the 2 canvas sheets) time and time again. AVOID! It's crowded, there's garbage, mice, a rotting cow carcass...
Day 3 Camp Bahia de los tempanos (-49,47994,-7298601) - el chalten
Last day of hiking. Very beautiful in the hills, views over the lake. We loved it. Cross country in the hills, very nice to do even if we had to pass a few muddy spots and lost the trail a few times. Once back on the official trail, no more worries. The zipline was easier than on the first day. We didn't have to wait very long, surely 2 people ahead of us. End of the day with an easy trail to el chalten. The last few kilometers are on the road, not very pleasant and uninteresting, but it's not very long.
This section is definitely beautiful and diverse. Mice are a real problem on this section. They seem to be present at all the bivouac spots. They're not shy and don't hesitate to come along even if you scare them. If we had to do it all over again, we'd use rat repellents, because hanging up the food doesn't seem to be enough.
24-Mar-05 to 2024-Mar-07 / 48 hours / Hiking / SOBO / RR / Tomáš
I did not like El Chaltén and the weather seemed better than later in the week so I immediatelly followed to GPT40. Starting at 17:00, I stopped 3 km from the first official camping Torro, which is normally 16 km far, in three hours of walking. I registered online and did not talk to any parkguards - not sure if they would not try to turn me back this late if they saw me. Fearing mice and being asocial, I did not want to reach the camp. The trail is very clear and easy. At least in this section, there are many places to camp - many trees provide shelter from wind. It was not that windy anyway, just on the final descent to the valley. Met lots of people coming back from Pliegue Tumbado mirador and nobody after the junction.
The next morning surprised me (the only reliable forecast seems to be for heavy rain or cloudless day, anything in between seems to be a hit or miss) by blue sky, so I got awesome views going up the pass. There was a queue at the zipline so I forded 50 m upstream - it was barely below my knees. Met ten people altogether that day. Walked on glacier, as the official PDF recomends. It is not slippery with the rocks. It is fun, there are footsteps to follow going on and off the glacier. I assume it is safe. There is also a trail going in parallel on the rocks (all circuit is trail BTW, not party CC like GPX suggests). Indeed only between the glaciers there is a few tentspots as indicated by OSM (unofficial? - but nobody probably cares). By the time I got to the first pass, clouds obscured Fitz Roy and the mountains across the icefield, which was still breathtaking. The pass had both quite windy spots and windless spots and some flats, so in good weather might be ok for camping, but hard to say. Traversing to the second pass, you actually mostly go through a valley partly (?) formed by ancient morraines, so most of the time, the icefield is hidden. I think there are places for pitching a tent, though not really between water at 35 and the second pass - anyway, the place around refugio is the most shletered. There used to be a campsite right after the second pass, but the PDF says you should not use it. Going further down is indeed very steep. There are now handy ropes attached to trees at places. The trail is badly eroded and slippery, would be indeed annoying when muddy. Darkness fell on me there and I still did not bother with a headlamp, but this is indeed the most demanding part of the whole trail. It is demanding also for GPT standards (the rest of the circui is easy). Once you get down, it is flat and you can camp in many places, which I did.
The next day there were about 15 people, three of which went clockwise, so it is done even if the Park does not like it (it normally has no presence on the trail itself). This time I waited the queue for the zipline to actually try using it. I think the river was fordable there. It was definitely fordable 200-300 metres downstream (there is a diversion), where it widens and branches in the delta. The rest of the trail was uneventful.
It is indeed a nice end to the GPT. I did not expect to finish the Main route (minus 23-31) this year, so yay! The El Viento shop (49.3229571S, 72.8940188W) is on the other side of the town (2 km) to the Park office and charged me for three days even though I finished the circuit in 48 hours - it was 5-6 USD per day. In retrospect, I would not bother with the harness. I met a guy who went without because he could not rent one - I was given the last one they had available and it was too big for me by far. Should the second river prove unfordable, people would probably borrow you theirs, it seems one set is usually carried per group and passed over using the thin rope - at least on the second crossing, the thin rope is there permanently so I am not sure what would the thin rope be for anyway.
I still hated El Chalten (too many tourists, really bad 4g internet [apparently everybody in town shares one connection, unless I was wrongly informed] - if you stay overnight, usually in such situations it starts working well some time after midnight when everybody sleeps -, really pricy produce and very bad meal in one of the restaurants; Villa O'Higgins has a much nicer feel), so I hopped on a bus (3h) to El Calafate at 18h for about 22 USD. It goes also in the morning and around noon. There is also a 130 USD 28h (I think) bus to Bariloche at 14:00 and at 21:00. From El Calafate, there are connections to Ushuaia (this one not sure), Puerto Natales and Punta Arenas (at 3 AM and change in the middle about 40 USD, a bit cheaper if youbhave cash) and Buenos Aires. I don't have my ticket, back yet and flying directly from El Calafate would be very expensive, prices from Punta Arenas were the cheapest. Bye!
2024-Feb-16 / 4 days / Hiking / SOBO / RR / Charlie Gardner
What an outstanding hike. This is definitely such an incredible way to either begin/end the main route of the GPT. We did it in the classic 4 days which was fairly chill.
Day 1 - Pretty straightforward day. Hike starts with a nice climb that takes you eventually into the surrounding forests. Great views of Lago Viedma from the top and a nice lunch spot. We started very late in the day and the sun was BEATING, could recommend and earlier start to avoid this. Don’t forget to check in with rangers before leaving! Quick form you have to fill out. Hang your food at Toro campsite, we saw a few mice running around.
Day 2 - Winds were crazy in the valley when we woke up. Many hikers were considering bailing on the hike due to worries of what Paso del viento would hold but the they calmed down around 930-10 and most pushed on. There’s an alternative route across the rivers that funnel into Laguna Tunel o Toro that we thought we’d check out as a few kairns led that way but they were far too strong to cross when we went that way. Ended up having a route find a bit and scramble up an alternative route after this lake, definitely recommend staying as close to route as possible here. Trail opens up again after you make it over. Tyrolean was short, didn’t look like anyone tried to ford the river here but it was definitely doable. Get to tyrolean early if you want to avoid waiting. The glacier route required a bit of route finding as well at points but isn’t anything crazy. Boulders and rocks can be loose at times though. Maybe we got lucky but paso del viento was quiet when we got to the top. Outstanding views! Short walk to camp after the descent from Viento. 8 of us slept in the shelter at paso del viento Camp as winds picked up considerably overnight. Was definitely glad for the protection but there were definitely mice scurrying around.
Day 3 - Definitely recommend an earlyish start this day. The climb up to paso Huemul is not as hard as paso del viento but the decent afterwards is just ridiculous. If you have bad knees, it’s more of a controlled fall on some sections. Gravel is extremely loose and it is VERY steep. Thankfully, there are a fair amount of the roots and trees to grab hold up but this was definitely an annoying decent especially at the end of the Day 3. Many tried Bahia de Los témpanos camp but we decided to push on to Bahia de Hornos. An hour later, everyone else showed up at this camp as they said the other one did not have sufficient shelter from wind and was fairly dusty. Hornos ended up being lovely after winds calmed down and sound got lower. Would probably filter water here if possible, lots of cows nearby and water is fairly foggy.
Day 4 - Final day was straightforward but definitely longer than expected. Would definitely recommend leaving early to be first at the tyrolean again. Be careful with the safety rope, ours broke halfway while pulling bags across and we had to send a person across without the pulley.
Enjoy, this hike rocks!

Not much to add. As the others mentioned a must do! When I started, there were indeed not that many people as weather forecast was not that good for the 'classic' 4 day itinerary. I was fine doing it in 3 days. The bivouack after Glaciar Rio Tunel Inferior only has space for 3 tents. You find additional protected spots 5 minutes beyond at the lake. If you fear glacial lake outburst flood (GLOF) there are also some elevated spots there.
- 2024-Jan-06 to 2024-Jan-08 / 2.5 days / Hiking / anticlockwise / RR / Stiina & Kris
We started around noon on day 1 and hiked to the bivouack after Glaciar Rio Tunel Inferior at km (km 21.2). We walked acrosse the glacier to avoid the moraine, no crampons needed. The bivouack was extremely windy at night but still a bit protected, lots of big rocks to help with staking the tent down. There are also a few rock walls built.
On day 2 we hiked over Paso Viento (which was very windy indeed; we also had rain, hail and snow) and down the other side. Once we got lower down we got out of the cloud and the weather was very pleasant. We didn't have much of the view over the glacier to the North but saw the end that descended towards Lago Viedma. The Paso Huemul was also extremely windy but at least it was sunny. The descent through the forest after the pass is really steep, with loose gravel/sand and lots of tree roots - be extremely careful here! The official campsites at the bay and peninsula were full so we continued until km45.2 where there is a nice windprotected campsite shown on OSM. Ford at 44.2 is completely dried out, but at 45.5 the stream is flowing.
On day 3 we hiked back into El Chalten by lunch, it was a very windy day. When we reached the tyrolean at km54 (which is waymarked as a bridge for some reason?) there were about 15 people in the line so we decided to ford the river about 30m upstream. We went 3 people in a line formation, the first person had water up to the waist, the last just below hips. At km62, where you need to climb below a fence just before joining the road, pay attention to the small holes in the sandy banks: those are armadillo burrows, you might see one if lucky!

Even if there's lot of people (around 15/20 departure per days at this time of the season), this section is in my opinion absolutely amazing ! The view on the icefield is outstanding ! I mostly followed the track, except on day two, where I continue to explore the surrounding of the Laguna de Los Esquies. Happy to be totally alone there, in front of this outstanding view. Hypnotic ! (It's almost the same that you can see at paso del viento, but closer to the icefield, and more chance to be by yourself here.
You have to rent harnais in El Chaltén and pass threw two zip lines. That was very fun !
I had a looooot of wind at paso del viento and paso del huemul. Reminds me tierra del fuego ! Could be very surprising as it's unpredictable squalls and so powerful !
The downhill after paso del huemul Is not funny as it's very slippery. Just have to take the time to be even more careful.
Views along the whole trek are absolutely stunning ! A must do !

GPT40 is no longer remote, there are 20 hikers on the trail every day. The trail is not marked, but not difficult to follow. No real river crossing necessary, there was always aid available. Snowfields are easy to cross.
Day 1: a little muddy, but easy to walk.
Day 2: Tyrolean Traverse is no fun as you have to pull yourself uphill. Alternative is an easy river crossing (knee deep, 10:00 AM good weather). 1km after that you can walk between RR or on the glacier (see presentation link at the end of this page). On the glacier trail you come back directly on the mountain of the same height. After the Paso del Viento (700m uphill in 6km, windy & cold) I leave GPT40 and walk to Campamento Laguna de Los Esquies to get a bit closer to the glacier. The path is difficult to find as there are many snowfields (without footprints) in between. But I am alone at the glacier lake.
Day 3: Mostly with CC back to GPT40 to Paso del Viento Camp
Day 4: Shortly after windy Passo Huemul is time consuming downhill (500Hm in 1km). The trail is very slippery (in sunny weather) & there is hardly any grip for the next step, take time for this part.
Day 5: very easy trail & Tyrolean Traverse is really fun (downhill zipline). Alternative river crossing is not easy (strong, 12:00 AM good weather).

Amazing section. We did the recommended 4 day itinerary (together with about 20 other hikers). A few points to add to the existing comments here: first, there was a lot of really wet grasslands, especially on day 1 (at least when we did it, early December). Accept your fate and live with wet feet (and bring extra socks if you can). Second, the four day itinerary makes use of the best-sheltered campsites. Other campsites may offer less protection. Note that even if the Park Rangers say conditions are good, you might encounter very strong winds in many areas. Third, if you want to extend the (somewhat short) days a bit, you can hike to the viewpoint Loma del Pliegue on day 1, on the ridge just above the campsite on day 2 (nice to watch the sunset), and to the aptly named mirador del cóndor next to Huemul pass on day 3. On day 3, it's best not to arrive too late to the very scenic Bahia de los Témpanos camp, since space is limited. Lastly, the descent from the huemul pass on day 3 is indeed a bit tricky, especially if you were to go in wet conditions.
One warning regarding water at the campsites: despite the park information claiming that the water is potable, we would recommend taking some care to get clean drinking water. On day 1, there is an excellent little stream 400m past the campsite. On day 2, take water from a little side stream ~600m before the campsite. The lack of the toilet means that the water from the river flowing into the lake is likely not safe to consume. Similarly on day 3, it is highly recommended to fill up plenty of water at the little waterfall at the end of the steep downhill section before going into camp. The lack of a toilet means that the water there is also unsafe to drink. Furthermore, next to the campsite is a carcass of a recently deceased cow. If the first three days gave you the impression that there is plenty of clean drinking water available during the day, be aware that this is not true of day 4. There is only one good looking stream, roughly at km52, and all the water will require treatment (we saw another three cow carcasses nearby the trail on day 4). Don't worry too much about this, if you plan ahead and think a bit about where to get the water, then it's no issue at all. Enjoy this excellent adventure!

Such a wonderful section ! One of our favorite ! Incredible views on the glaciers, with autumn's colors it was amazing !
It is recommended by the guardaparques to have good weather on day 2 and 3 (for the passes), no cloud and no wind for us : perfect.
We rented 1 harness for the 2 zip lines (day 2 and 4). 1 harness per group is sufficient but you have to rent a thin rope too in case the one in the pulley is broken. It is really worth it because the feeling is so good ! (We rented at Viento Oeste, north of San Martin street, the cheapest according to a friend).
The thin rope is very helpful to suspend all your bags and things in camps. You have to do it because mice are at every camp and the will destroy your bag, your tent or whatever has food inside. This is the only annoying point of this section.
About the trail : easy to follow, except when you have to walk on the glacier on day 2, it can be a bit challenging. Take care, do not go if there is fresh snow all over the glacier.
The way down the paso Huemul on day 3 is very steep too.
Do not forget to register online with the guardaparques (and to check out when you return !).

We did the Huemul Circuit in 3 days. We started around 9 a.m. planning to camp at the Biwak Túnel the first night. The weather turned out to be so nice that we decided to continue and do the Paso del Viento the first day.
The trail until the first Tyrolean traverse was really good even though it was partially covered in snow. We crossed the river easily by foot. After that the trail up to the pass gets more demanding and slower. Once you reach the Glaciar Túnel Inferior navigation gets more difficult. There are different paths and we firstly followed one going up and down on the gravel. It's probably easier to take the path on the glacier from the beginning on. We reached the pass at sunset and had an absolutely amazing view.
We decided to camp at the end of Laguna Ferrari (to avoid the mice problem at the main campsites). The path to the lake was demanding, because the slope was covered with lot of snow and it was dark. At the campsite there are lots of well protected spots for tents.
The next day we slept pretty long to recover from the previous big day and with better weather than anticipated we walked until km 39.3. There are two really good camping spots, one at the edge of the trees and one inside the small forest. No mice there.
The steep trail down wasn't super easy and must be hard during rain. The second river crossing at km 54 was much more demanding. We crossed it further east of the Tyrolean, where the river divides in multiple branches. There the water went below Annas hips (1,63m). We walked to the viewpoint at km 62.4. Lots of people watched the sunset there with a great view of Fitz Roy and it was easy to get a ride for the last 2 km to El Chaltén.

I had the luxury of being able to wait for a good weather window and it really payed out. My hike was easy with magnificent views when climbing up to Paso del Viento. I even had a tranquil lunch at the top. The glacier walk and the snowy peaks are stunning.
However, I believe gpt40 can turn into hell in windy weather or if camping outside the wind-sheltered camps. I met several people in El Chaltén who had to turn back because the wind didn’t let them climb up to the pass. One couple also had their tent teared apart in the middle of the night at Bahía de Hornos. If you can, avoid camping there for the last night. Instead, camp at Bahía de Tempános which offers far better wind protection.
I enjoyed the recommended 4 day length. Each day section took me around 5-6 hours of walking. I believe that especially Day 1 and 2 could be combined into one (El Chaltén - Refugio del Viento) if the weather is favourable.
Mice seem to be present at all of the official camps - best is to hang your food, cooking utensils and hygienne stuff on a tree away from your tent and avoid eating in your tent. I did that and had no problems with the animals, while some of my companions got holes bitten into their tents and other stuff.
I rented harness and carabiniers for the tyrollean traverse at Viento Oeste. The traverse was fun to use and I was happy that I didn’t need to ford the cold rivers. Recommended!

This is a tough one, I didn't make it. I waited out a few rainy days in town until the park office told me we had a good two day window.
I spent the first night at Laguna Toro. Be careful of mice there. Quite a bit of rain and snow, but still too warm for the snow to stay on the ground. The next day we (25 or so tourists) set out to attempt the pass.
I crossed the river on foot right by the zip line, the water was below my knees at noon. Painfully cold though. I climbed up until I got a view of the first glacier at which point the wind was too strong for me to trust my footing. I went back to the first camp planning to wait and try again the next day.
Just after setting up the wind tore down a big green tree branch, which crushed and ripped my tent. Thankfully I wasn't inside. Walked back to El Chaltén in defeat.
I guess that's the end of my GPT hike. It's been amazing, other than the miserable weather down here in the south!

Route: Centro de Visitantes - Laguna Toro - Paso del Viento - Paso Huemul - Bahía de los Témpanos - Centro de Visitantes
We hiked the Huemul Circuit in 4 days as recommended by the Park officials. You could do it in less, but it is so beautiful and it was nice not to rush and to take it all in. The park staff also informed us of the expected weather conditions. You only really need favourable weather on the 2d and 3d day, going over the two passes. It was extremely windy when we went, knocking me off my feet at times.
I enjoyed having my microspikes for the crossing of Glaciar Túnel, allowing me to explore a bit further up on the ice, but they are not necessary. From the top of Paso Del Viento, the view of the Southern Patagonian Icefield is awe-inspiring, but there are no good sheltered spots at or near the top to pause and admire the view for very long before the descent.
The Paso del Viento Camp (second night) is the most exposed of the camps, the tent sites are semi-protected by low rock walls, and some are better than others. The trail is easy to follow and is well-marked.
We rented harnesses and cord for the Tyrolean traverses from the gear shop Viento Oeste, at 1,400 pesos per person per day. The cord was 250 extra pesos per day. It was fairly straightforward to figure out how the cable crossings worked. The first crossing of Río Túnel on day 2 seemed fordable, but not the second one on day 4. That Tyrolean traverse also did not have a rope to pull the pulley back, so we were glad to have one.

Big forest fire around the 3rd bay near iceberg bay. Circuit was closed for a bit. Unsure on how well it's recovering. Have a chat with the rangers before leaving.

Same as below, follow the trail when it differs from the trace. Beware that on Day 2, the Paso del Viento can be very windy and you should check the weather forecast before leaving.

>Trail was very easy to find.
>Wind guru was for us completely unreliable. Very strong winds to the point of blowing us off path for minutes at a time whilst predictions were minimal forecast. Heed advice from rangers.
>First river crossing was impassable. Worth bringing harnesses for zipline (worth it for the fun) The far far end of el chalten there's a shop called vende oste where we found good rates of hiring harnesses.
>If it's windy on the 3rd day pitch up in the iceberg bay bivi site rather than the second site. We stopped earlier than the rest of the gang due to being a bit tired. We had very peaceful night in strong winds where friends at the next site a hellish night. Iceberg bay was also my number one campsite of all GPT40-30! Watching icebergs flip to the sunset after a long dusty day of slipping sliding and being gusted off the path by winds on the mornings pass. This place is a true refuge for the soul.
>Ferry not running so not many options to hitchhike back to chalten for last part of last day. The liberal use of gaiters on trainers also recommend. Lots of spiky grass seeds and burrs on last days
> Very much worth the wait for a weather window. Incredibly diverse veiws. The glacier walk was a one of kind! Veiws of the ice field kinder the feeling of being about a small at a ant.

Watch video of the hike @ national park office. Bring a harness & learn how to do a Tyrolean traverse before you go (the NP video is useful for this) Where the trail differs from the track file it's easier to follow the trail which is generally good & clear. You are required to register online for the trek (link given by Veronica & Zach) & sign out at the national park office when you are finished.
The river above Laguna Toro was waist deep & v fast, it nearly knocked me over. Not recommended to cross in the afternoon. In the early morning it may be only knee deep. Bring the harness anyway & learn how to use it, you may need it. On the glacier stay near the edge, people tend to go too far out. At the far side you should see footprints & cairns leading to the moraine. Camped @ small high camp just after exiting the moraine (Vivac Tunel) There are a few stone corrals there. Lined the tent with rocks - pegs alone will pop. Good & sheltered camping @ Laguna Toro & after Paso del Viento @ Refuge but I went from Vivac Tunel over Pasos Viento & Huemul in 1 long day. Only a little snow @ Paso del Viento & easy to cross. Very windy on Paso Huemul in the afternoon. Steep & loose descent, slow going but I saw 2 huemul. Amazing views of the Icecap between the two passes. Campsite @ Iceberg Bay one of the best on GPT. You can watch the bergs that calve off the icefield breaking up. At lower Rio Tunel we forded 300M downstream from the cable where the river is braided into channels. OK to cross @ noon, knee deep & fast but you need to pick a good spot. Definitely not fordable @ the cable where it runs deep in a single channel. Challenging hike but incredible views of the Icecap.

2 days anticlockwise. Trail is easy to follow. Talk to the rangers and they can let you know about any issues. Would be tough in bad weather but in clear weather there are no issues. For the glacier walk we were told to enter the glacier just after the beginning and to exit just after the end. I suspect due to the increased popularity a new route has been made in sections so follow the trail markers which divert from the GPX route.
We hired harnesses in El Chalten for the river crossings. We crossed the first on foot in the morning and had no issues. The second one we crossed using the equipment for the novelty but the river looked fine to cross further down. However I can see the river being hard to cross in high levels of rain.
This was a very beautiful section and very different to the northern sections.

Did the trek counterclockwise wich is the only way to do it rangers say. You need to register to do this trek and guardaparques vive great advises. I crossed the rivers by foot and they were pretty hard, I recommand using the zipline. Awesome views with good weather, but the wind is really annoying! The campgrounds rangers told me to camp weren’t the ones on the trackfiles, but are pretty close to them so they are not hard to find. Great experience !!
Verify the wind forecast! The hills are so steep, strong wind could be dangerous! There’s no snow anymore and you will not need crampons.
- 2019-Dec / 3 days / Matthieu
We did it in December with good weather, in 3 days ( instead of the 4 recommended, 2 first days in one big day). Awesome trekk and views. It is better to register first at the guardaparques office.
Trekk easy to follow excepted on the walk on the glaciar before the paso del viento (a little one, not the Viedma). During this walk, I would not advise to try to walk by the wall of mud and rocks at the left of the glaciar, it is a steepy way and everything slips, we tried it and went on the ice after. The little walk on the ice just near didn´t feel unsafe to me, with the little rocks it doesn't really slip.
Good camping sites, well protected from the weather conditions.
The last downhill after the paso de Huemul is the most dangerous part, very steepy but with trees to hang for help. I would advise to do this part with good weather conditions, with mud it could be dangerous.
For the rivercrossings (2 real ones) there is one way walking and one way with tyrolean on a zip Line. We did it with with the tyrolean, and it was extremly funny. Rental of material possible in El chalten. Of course you have to know how to insure yourself good, so inform yourself before going, it is not hard to understand though, but extremely dangerous if not done well. None of us had experience with it before.

After we have taken the information at the national parc office, we only had 2 days of correct weather. So we decided not to walk the entire section but to go only to the paso del viento to get the view on the campo de hielo (glaciar viedma), following the advises of the guardaparques.
I think it is the highlight of the section but not sure since I have never walked it entirely.
On the first day we also took the time to walk to the summit of the cerro loma del pliegue tumbado (1500m of height). It offers an amazing view on the fitz roy and on the cerro torre, the 2 rockstars of El Chalten.
On the second day we went to el Paso del Viento. The view there on the campo de hielo is absolutely fascinating. The hike is very tough but is absolutely worth the effort. You walk on a glaciar during 2kms but no equipment or particular skill is needed. It was very very very windy (and happily it was a quiet day I do not imagine on other day).
Day 1 : El Chalten-cerro loma del pliegue tumbado-laguna torro : 27km with big elevation gain (around 1700m) Day 2 : laguna toro - paso del viento - laguna toro : 18km. Day 3 : back to El Chalten : 17km.
I definitely recomand to follow the guardaparques advises and pay a huge attention to the weather. On this section with a bad weather and a strong wind I think it is dangerous to try to walk it entirely. And if it is cloudy, you will miss amazing views.
The riverford after the laguna toro was easy on the way to the paso del viento (on the morning) but very dangerous on the way back (on the afternoon with all the gletchers melting I think). The worst we've done yet. If you intend to get back after the paso del viento I advise to get equipment to be able to use the zip line that has been settled by the guardaparques. It us much more secured than crossing the river on the afternoon.

Equipment for Zip Line to cross rivers is not required anymore since this season.
Most of the season the rivers are possible to cross on foot
Paso Viedma had a decent amount of snow on it (Snow Line at 1000m), the ascent is straightforward but the descent on the side facing the ice field can be really iced over and difficult without crampons (ask at Visitor Center of the NP for current conditions)
- 2019-Nov-4 / 4 days / regular hiking route / counter-clockwise / Lea Geibel, Kevin Moe
Beautiful hike in good weather! Great views of the ice sheet and mountains from Paso Del Viento. Highly recommend waiting for clear weather so you don't miss the scenery! We went up right after a big storm. The trail was a bit muddy up to the Laguna Torro, and the lee of the pass had a decent amount of snow. The windward side was pretty icy and more difficult than the snow. The next day we took a detour and cut cross country to walk on the Campo De Hielo Sur. Our route took a bit of steep scrambling to get down to it and back up around Paso De Huemul, and there were lots of open crevasses on the ice, so it would be good to have some experience and navigation skills if you want to do the same. Dropping down Paso Huemul on the trail was steep and a knee killer, and from Lago Viedma we had a hard time staying on the right trail amidst all the cow path, but aside from a few spiky bushes it's easy to cut cross country. Unnecessary to use the zip lines this year to cross the rivers. You have to camp only in the designated campsites.
Season 2018/19
Season 2017/18
- Route description by Kara Davis after Season 2017/18:
Notes to consider before beginning: GPT40 is more popularly known as the Huemul Circuit, a 57-kilometer trek in El Parque Nacional Los Glaciares. Before embarking, the national park guard requires that every hiker obtain a permit, bring required safety gear, and watch a slideshow about the circuit. The safety gear consists of a harness, 2 carabiners (one steel and one aluminum), slings, and 35 m of rope. Most of this gear can be rented at any outfitter in town, but due to liability reasons, the outfitters won’t rent rope. We went to the local ferretería to purchase this. All of this gear is used for two river crossings on zip lines.
We were told that the rangers required hikers to bring their safety gear to the station before a permit would be issued. I would recommend that anyone who wants to do this circuit go to the rangers station the day before to watch the video and get any other necessary information about weather, conditions, etc. Since rentals can get expensive, renting the same day you leave and then going to the rangers station to show them your safety gear and get a permit seems to be the best course of action. The guard station is located on the south side of the Río Fitz Roy just across the bridge.
Most people hike the circuit clockwise (as the slideshow recommends). The trail begins just behind the rangers station and ascends up gentle grassy hills. It is fairly flat and well maintained. After passing Laguna Túnel o Tore, the trail deviates from the GPS route and loops to the first crossing of the Río Túnel on a zip line. During low water, it is possible to cross this river on foot by following the GPS track. After crossing the river, the trail climbs steeply to just above Glaciar Río Túnel Inferior. Along the south side of the glacier, the trail becomes hard to follow as it disappears in loose moraine. Walking on the edge of the glacier may be easier than trying to pick your way across the steep slope but be careful doing this.
After passing the glacier, follow maintained switchbacks up the side of the mountain towards Paso del Viento, the high point of the circuit. For the next 20 km, expect amazing views of Glacier Viedma. I cannot speak to the quality of the trail descending from the pass because of the blanketing snowpack that was present during our trek, but the sections where the snow did melt looked maintained. There is a small refugio, Refugio Paso del Viento located at a pond about 3.5 km from Paso Viento.
After passing the refugio, the trail contours and then climbs to Paso Huemul. Make sure to look back and enjoy the last view of Glacier Viedma. The descent is very steep and at one point there is even a rope to downclimb. There are also plenty of woody bushes (manzanita?) to cling to as you lower yourself down the trail. After completing the descent, the trail is straightforward and easygoing. There is camping on the beach at the peninsula, Camping Bahía de Hornos. There is one more river crossing with a zip line at the lower Río Túnel, and from there it is easy walking to the end!
