Backpacking in Laguna de los Tres
🏆 Top pickhike ranked #2
By Johan Kruseman 🇳🇱 | Updated October 19, 2026

Everyone tells you the payoff at Laguna de los Tres is the turquoise water. Wrong. It's the glacier calving off Fitz Roy's east face while you're still eating lunch on the moraine. This hike sits in Los Glaciares National Park, near El Chaltén, in Argentine Patagonia. It's a demanding out-and-back, roughly 20 kilometers round trip, with a brutal final kilometer that gains most of the elevation in switchbacks over loose scree. The trailhead starts right in El Chaltén town, no bus or shuttle required, just like the Laguna Torre trail. My legs were screaming on that last pitch, lungs burning in the thin wind, and then I crested the ridge and just stopped. The lake was glacial-blue glass, Fitz Roy's granite spires stabbing straight up behind it, and I stood there eating a squashed alfajor like it was a five-course meal.

✨ Why go?
Ranked #2 hike in Argentina
What sets this place apart

Laguna de los Tres is the reason most people come to El Chaltén at all, and the logic holds up. The trail ends at a turquoise lake directly under the Fitz Roy granite wall, a face that rises more than 2,000 meters above the water. Few day hikes anywhere put you this close to a peak of that caliber without a rope or a multi-day commitment.

The trailhead sits at the edge of town, so there is no bus or taxi to line up, only the park pass to buy (about US$33 a day for foreigners). You lace your boots at your hostel door and walk. That alone makes it a rare find in Patagonia, where most big views demand a long transfer first.

The distance is also flexible. Plenty of people turn around at the Mirador Fitz Roy or camp at Poincenot to catch first light on the peak, while others link the lake with … read more 👉

The distance is also flexible. Plenty of people turn around at the Mirador Fitz Roy or camp at Poincenot to catch first light on the peak, while others link the lake with Laguna Capri or loop back via Laguna Madre e Hija. The final 400-meter scramble up loose moraine is steep and slow, and it is what separates this from a simple stroll. Pair it with the Cerro Torre trail and you have a tidy two-day sampler before moving on toward El Calafate or Torres del Paine.

💡 HighlightsThe experiences that define the visit

  1. Laguna de los Tres itself The payoff view: a milky turquoise-grey glacial lake sitting directly beneath Fitz Roy's granite spires. The color shifts through the day depending on glacial silt suspension and light angle, and on a clear morning the peak reflects almost perfectly on calm water. Nothing prepares you for the scale of Fitz Roy once you crest that final ridge.
  2. The final ascent switchbacks The last kilometer gains roughly 400 meters over loose scree and rock, and it's brutal after already walking 10km. But it's also where the trail earns its reputation: each switchback opens a wider slice of the Fitz Roy massif until you're standing right under it.
  3. Laguna Capri A calmer, lower-altitude lake about a third of the way in, with Fitz Roy visible across still water on windless mornings. It's

  3. Laguna Capri A calmer, lower-altitude lake about a third of the way in, with Fitz Roy visible across still water on windless mornings. It's a smart breakfast or turnaround spot if you're short on time or energy, and far less crowded than the main laguna.
  4. Poincenot Campground The last camping spot before the final push, tucked in southern beech (lenga) forest at the base of the ascent. Staying here means you can hit the summit trail at dawn before the wind picks up and before day-trippers from El Chaltén arrive.
  5. Fitz Roy massif views from the approach trail Long before you reach the laguna, the trail through lenga forest opens periodically to reveal the jagged Fitz Roy and Poincenot peaks. These framing moments through the trees are some of the best photo opportunities on the whole route, and they build anticipation properly instead of dumping the view on you all at once.

🌤️ When to go?Choosing the right time of year

  • Summer (December to February): The prime window. Daytime temps run 15-22°C (59-72°F), skies are clearest, and the long daylight gives you room to start late and still reach the lake before dark. This is also peak crowd season, with the Fitz Roy trail packed and El Chaltén's few hospedajes charging their highest rates.
  • Shoulder Season (October-November, March-April): Fewer hikers, prices ease off, but wind picks up and temps drop to 5-15°C (41-59°F). Patagonia's infamous gusts hit hardest in November.
  • Winter (May-September): Snow can close the upper trail entirely, daylight shrinks to under 9 hours, and many El Chaltén businesses shut down.
Aim for early March. The crowds thin after Argentine summer holidays end, but the weather window hasn't closed yet.

Estimated Duration: 8 to 10 hours for a strong day hiker; many backpackers split it over 2 days using Poincenot or Laguna Capri campgrounds.
Difficulty: Moderate overall, with a strenuous final kilometer of steep, loose scree gaining around 400 meters in elevation.
Starting Point: The trailhead begins right in El Chaltén, at the northern end of Avenida San Martín. No shuttle needed since it starts from the town itself; buses from El Calafate (roughly 3 hours) run daily into El Chaltén's bus terminal, a short walk from the trailhead.
Major Landmarks:
  • Laguna Capri: A lower lake with early Fitz Roy views, roughly a third of the way in.
  • Poincenot Campground: Free backcountry camping just before the final ascent.
  • Laguna de los Tres: The turnaround point, a glacial lake directly beneath Fitz Roy.
Terrain and Scenery: Mostly packed dirt trail through forest and open steppe for the first 9 km each way, transitioning to loose rock and scree switchbacks for the final steep climb.
Vegetation: Southern beech forest (lenga and ñire), giving way to sparse alpine scrub and bare rock near the laguna.
Wildlife: Guanacos and Andean condors are commonly spotted along the lower trail and open steppe sections; foxes occasionally appear near campgrounds.
⚠️ Hiking info can sometimes be outdated or inaccurate. Before you hit the trail, check the latest conditions with locals. If you do spot anything that's off, I'd love to hear from you, so I can update it for fellow travelers.

🛡️ SafetyScams, Hazards, and Annoyances

This trail is well-marked and heavily trafficked, so navigation isn't a real concern. The main issue is Patagonian wind, which can turn ferocious without warning, especially on the exposed final ascent. Check conditions at the park ranger station before heading out, and be ready to turn back if gusts get aggressive near the ridgeline, since the loose scree there gets genuinely unstable underfoot in strong wind. Weather flips fast: pack a real waterproof shell even on a clear morning. Water sources along the trail are drinkable without treatment in most spots, a nice break from typical backcountry rules. Guanacos are harmless and common; give condors space if you spot one perched nearby. First-timers often underestimate the final kilometer, budget more time and energy for it than the rest of the hike combined.

FAQCommon questions from travelers

Laguna de los Tres is a round trip of about 20 to 22 kilometers from the trailhead in El Chaltén, which most hikers finish in 8 to 10 hours including breaks. Count on roughly 4 to 5 hours up and 3 to 4 hours down, with the trail starting at the end of Calle San Martín in town. Many people start by 7 or 8 a.m. so they reach the lagoon with enough daylight to spare, and an alternative start from Hostería El Pilar adds distance but makes a one-way route possible.
Moderate to demanding is the fair rating: the route is well marked and has no technical sections, but the length and the final climb make it a long day. The first 8 kilometers to Poincenot camp are mostly gentle, and then the last hour climbs about 400 meters in roughly 1 kilometer over loose rock, steep and tiring. Total elevation gain is around 800 to 900 meters, and wind or cold at the lagoon can be harsh even in summer, so pack warm layers.
No guide is needed for Laguna de los Tres, since the trail is clear and heavily used. Entry to Los Glaciares National Park’s Chaltén sector requires the park pass, about US$33 a day for foreigners, and registration at the visitor center is encouraged. Camping at Poincenot or Capri is possible with a free permit at the visitor center, and guided day tours are available from about US$50 to 100 if you want company or transport.
⚠️ Things can change over time, so always validate details locally before you go.

We 💚 feedbackKey takeaways before you go

Standing under Fitz Roy at that lake is worth every early wake-up call, the view genuinely rearranges your sense of scale. But go in knowing the wind can shut the whole thing down with zero warning, so build a buffer day into your El Chaltén stay rather than banking on one shot at the summit.
