Laguna de los Tres is a glacial lake at the foot of Monte Fitz Roy in Los Glaciares National Park, Argentine Patagonia. The trail starts at the edge of El Chaltén and is the most popular day hike in the park — long, exposed to wind, and finished by a steep final climb, but non-technical and achievable by most fit hikers. This guide covers the route, difficulty, weather, packing, and local support.

Getting there: El Calafate to the trailhead
The nearest airport is El Calafate (FTE). From there it is roughly 215 km (about 3 hours) by bus or car north to El Chaltén; buses run several times daily in season, so book ahead in January and February. There is no airport or fuel station in El Chaltén itself.
The trailhead sits at the northern edge of town, a short walk from any hotel or hostel — no taxi or shuttle is needed. The signed path to Laguna de los Tres and Campamento Poincenot begins directly behind the last streets of the village.
Route and key waypoints
- Trailhead, north El Chaltén (0 km) — a steady climb through lenga forest for the first hour, with early views over the Río de las Vueltas valley.
- Mirador Laguna Capri (~4 km) — first clear view of the Fitz Roy skyline, and a common turnaround point in poor weather.
- Laguna Capri (~4.5 km) — lakeside viewpoint and free campsite; the classic reflection photo of Fitz Roy is taken here.
- Campamento Poincenot (~9 km) — free campground at the base of the final climb; the last sheltered spot to eat, layer up, and check conditions.
- Final ascent (~1.5 km, ~400 m of gain) — steep, rocky switchbacks; the hardest hour of the day, in both directions.
- Laguna de los Tres (~10–11 km, ~1,170 m) — the glacial lake directly beneath the Fitz Roy spires. Return by the same trail.
How hard is it? The final ascent
Most of the trail is moderate — steady forest climbs and long rolling sections. The difficulty is concentrated in the last 1.5 km: about 400 m of steep, loose, exposed climbing with no shade or shelter, where wind and cold hit hardest. If a 20 km day with 1,000 m of climbing is unfamiliar to you, train beforehand, start early, and treat Campamento Poincenot as a genuine decision point rather than a formality.
Laguna de los Tres vs Laguna Torre
El Chaltén’s two classic day hikes suit different days and different legs. Many visitors do both.
| Laguna de los Tres | Laguna Torre | |
|---|---|---|
| View | Monte Fitz Roy, up close | Cerro Torre and its glacier |
| Distance | 20–22 km round trip | ~18–19 km round trip |
| Elevation gain | ~1,000 m, steep finish | ~250 m, mostly gentle |
| Effort | Moderate–strenuous | Moderate |
| Choose it when | You have your best-weather day | Legs are tired or wind is high up top |
Not the same trek: Torres del Paine is a separate multi-day circuit in Chilean Patagonia, a full day’s travel from El Chaltén. Laguna de los Tres is a day hike from town.
Weather and Fitz Roy visibility
Patagonian weather changes fast. Fitz Roy generates its own cloud cap and can stay hidden for days; clear summit views are never guaranteed, in any month. Wind is the defining factor — gusts on the final ascent and at the laguna are routinely far stronger than in town. Check the forecast the evening before and again at breakfast, and let conditions, not the itinerary, decide whether you attempt the final climb.
Hiking at sunrise
On clear mornings the granite east faces of Fitz Roy turn deep orange for a few minutes at first light — the alpenglow. To catch it from Laguna Capri, leave town around 4–5 am with a headlamp; to catch it at Laguna de los Tres itself, most hikers camp at Poincenot and climb in the dark. A dawn start also means calmer wind and an empty trail. Bring a warm layer for the wait — pre-dawn temperatures at the viewpoints are near freezing even in summer.
What to pack
- Layers — base layer, insulating mid, warm hat and gloves even in January.
- Wind protection — a real windproof shell; here this matters more than rain gear.
- Trekking poles — valuable on the final ascent and the knee-heavy descent.
- Water — 1.5–2 L; streams en route are commonly used to refill.
- Food — lunch plus extra; nothing is sold past town.
- Sun protection — high-UV sunscreen, lip balm, sunglasses, cap.
- Headlamp — mandatory for sunrise starts, sensible insurance for everyone.
- Sturdy footwear — broken-in hiking shoes or boots with grip for loose rock.
Best time of year
The main season runs October to April — the Southern Hemisphere spring and summer. December to February brings the longest daylight and the most people; November and March trade a little weather stability for quieter trails. Outside the season the upper trail can hold snow and ice and daylight is short; winter attempts need experience and equipment.
Gear rental in El Chaltén
Several shops in town rent trekking poles, headlamps, tents, sleeping bags, and stoves by the day. Renting locally is a sound option if you are missing one item — arrive a day early to sort gear, and reserve tents in advance in high season if you plan to camp at Poincenot for a sunrise ascent.
Park entry and registration
Access to this sector of Los Glaciares National Park is free and no permit is needed for the day hike. Camping at Poincenot or Capri requires registering at the ranger station (Centro de Visitantes) at the entrance to town — a quick stop where you will also get current trail conditions and any closures. Check locally for changes before you hike.
Turnaround and safety
Set a turnaround time before you start — most hikers should be leaving the laguna by mid-afternoon to be back before dusk. If wind at Poincenot is already hard to walk in, it will be worse above. Turning around at Capri or Poincenot is a normal, common decision, not a failure. Turn back if you are behind your time plan, the wind is staggering you, visibility is closing in, or anyone in the group is cold and wet.
Guides, porters & photography
You do not need a guide for this trail — but a local guide changes the day: pacing, weather judgment, and knowledge of the mountains. Porters carry camp gear for sunrise ascents, and a professional photographer can meet you at the alpenglow. These services are offered locally through Connect Patagonia. Send an inquiry below and we will reply with availability.

Frequently asked questions
Is Laguna de los Tres difficult?
It is a moderate to strenuous day hike. Most of the trail is manageable for reasonably fit hikers, but the final kilometre is a steep, rocky climb of about 400 m that many find the hardest part of the day.
How long does the hike take?
Most hikers take 7 to 9 hours round trip, depending on pace, breaks, and conditions. Allow extra time for photos at the top and for a slower descent on tired legs.
Is it dangerous in bad weather?
In poor weather the hike becomes significantly harder and the exposed final ascent can be genuinely hazardous in high wind or low visibility. Check the forecast, start early, and be willing to turn around.
Can beginners do this hike?
Many beginners complete it successfully, but it is a long day with a demanding final section. Prepare with some training, start early, pack properly, and pace yourself.
Do I need a guide?
A guide is not mandatory — the trail is well marked. A local guide is still valuable for pacing, weather timing, and decision-making, especially in shoulder season or if you are unsure about conditions.
