The Laguna de los Tres trek is El Chaltén's most famous hike: about 20-25 km round trip, 8-10 hours, medium-high difficulty, and free to hike. It ends facing Mount Fitz Roy and its glacial lake. From El Calafate (~3 h away) it is best to start very early —the first regular bus arrives around midday— or stay overnight in El Chaltén.
What is Laguna de los Tres and why is it El Chaltén's most famous trek?
Laguna de los Tres is a glacial lake at the foot of Mount Fitz Roy (3,405 m), the icon of El Chaltén, Argentina's "National Trekking Capital".
The name comes from the three peaks that crown the massif. It is the most sought-after view in Argentine Patagonia, and you reach it on foot only: there is no vehicle access. Before you go, see how to get there in the guide on how to get to El Chaltén from El Calafate.
How long and how far is it?
- Distance: ~20-25 km round trip (depending on the starting point).
- Time: 8-10 hours in total, at a relaxed pace with photo stops.
- Elevation: moderate for most of the way, with a very steep final kilometre (the last climb to the viewpoint, about 400 m of ascent in just over 1 km).
- Access: the hike is free and self-guided; the trail is well marked.
What level do I need? Is it hard?
It is a medium-high difficulty hike, but not technical: no climbing gear or guide is needed. Most of it is gentle up and down; the demanding part is the last kilometre, steep and with loose rock, which takes about one hour to climb.
With good general fitness and enough time, most travellers complete it. The first sections (up to Laguna Capri) are suitable for anyone who wants a shorter version of the walk.
What is the route step by step?
The classic start is from the north of El Chaltén (via Av. San Martín); a more scenic variant begins at Hostería El Pilar.
- Km 0-4 · Viewpoint and Laguna Capri: initial climb and first views of Fitz Roy. A good rest spot.
- Km 4-9 · Valley and Poincenot camp: a flatter stretch through forest and peat bog, with the massif in the background.
- Km 9-10 · The final climb: the steep kilometre up to the viewpoint. The hardest section and the most rewarding.
- Arrival · Laguna de los Tres: the glacial lake at the foot of Fitz Roy. To one side, looking down, you can see Laguna Sucia.
- Return: back the same way (or descending towards Laguna Capri).
Can I do it in a day from El Calafate?
You can, but it is very demanding: ~3 h of travel each way plus 8-10 h of hiking. The key is timing: the first regular bus reaches El Chaltén around 11 a.m., which leaves the day very tight for a hike of this length.
Two ways to solve it:
- Leave very early on a private transfer: you gain 3-4 hours of margin over the bus and reach the trail with time to do the full hike and return the same day.
- Stay 1 or 2 nights in El Chaltén: the most comfortable and recommended option to enjoy it without rushing (and tackle other hikes).
What is the best season and time to do it?
- Season: from October to April (spring to autumn). In winter there is snow and fewer daylight hours.
- Time: start early in the morning. Fitz Roy is usually clearer at dawn, and Patagonian weather changes fast: strong wind and clouds can cover the summit by midday.
- Margin: it is better to reach the top in daylight and return calmly, not racing the clock.
What should I pack?
- Trekking footwear (the final section is loose rock).
- Layered clothing + windbreaker or waterproof jacket (the weather changes several times a day).
- Water (~2 L; up top, mountain streams are drinkable), snacks and lunch.
- Sunscreen, a hat and sunglasses.
- No technical gear: it is a demanding hike, not a climb.

Many travellers ask me whether Laguna de los Tres can be done in a day from El Calafate. I tell them the truth: it is long and demanding, and the best option is to stay overnight in El Chaltén. But if you are fit and want to do it in a day, I arrange a very early departure so you arrive with time — something the regular bus does not allow.
Whether you go for the day or stay overnight, a private transfer gives you what the bus does not: you leave at your own time and travel door to door. You hike; I take care of the drive.
