==Season 2023/24==

Beautiful trail. Not too much to add from what others have mentioned, the route is well marked. Views of the southern patagonia icefield are absolutely stunning. We decided to push a bit further and camp at Bahia Hornos, but I would have stayed at Bahia de Los tempanos if I did it again.

Perfect conditions! No clouds, no wind

I liked the hike, but hated the littering, I mean "shittering" around the official camps.

Day 1: RR [0.0-21.2]

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

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.

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.

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.

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.

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.

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 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.

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.

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.

==Season 2022/23==

Such a wonderful section ! One of our favorite ! Incredible views on the glaciers, with autumn's colors it was amazing !

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 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.

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 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

This is the link to register for the trek online: docs.google.com/forms/d/e/1FAIpQLSfP8lEz5ry97gEK6fzx2mlu1NAhPwBx8cRlnSZOH8mx8iUMHA/viewform

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.

The far far end of el chalten there's a shop called vende oste where we found good rates of hiring harnesses.

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.

==Season 2021/22==

==Season 2019/20==

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.

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.

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.

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.

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.

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)

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 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.

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!
