LAGUNA DE LOS TRES, FITZ ROY

7 - 9 HRS | 21.8 KM | 910 M | EL CHALTÉN - EL CHALTÉN

The Laguna de los Tres hike is a bucket-list trail for adventurers visiting Argentine Patagonia. Beginning and ending in El Chaltén, this 21.8 km loop offers breathtaking views of the Andes, glaciers, and rugged landscapes. With a 910-meter elevation gain and a duration of 7 to 9 hours, this challenging yet rewarding hike is one of the most iconic routes in the region.

Río de las Vueltas

The trail begins at the end of Avenida San Martín, right in the heart of El Chaltén. A steep initial climb sets the tone for the adventure, offering an early reward: panoramic views of the Río de las Vueltas valley. From here, the path levels out, winding along the Del Salto stream through lush forests, rocky terrain, and open heathlands.

At around the halfway mark, hikers reach the Poincenot Base Camp, a peaceful spot perfect for a short break or an overnight stay. The camp sits against a backdrop of towering peaks and provides a serene rest area before the trail’s most demanding section.

De los Tres Glacier

From Poincenot, the trail becomes increasingly challenging, culminating in a steep, rocky climb to the ridge of the De los Tres Glacier moraine. This 400-meter ascent is strenuous but well worth the effort. At the top, Laguna de los Tres greets you with its turquoise waters reflecting the awe-inspiring granite spires of Mount Fitz Roy, Cerro Madsen, and the Los Tres Glacier.

For those starting their hike before dawn, sunrise at the lagoon is an unforgettable spectacle as the peaks light up in fiery shades of orange and red. Nearby, a short detour reveals Laguna Sucia, a quieter spot known for its dramatic hanging glaciers and secluded atmosphere.

Plan your adventure

The hike is accessible year-round, but conditions vary with the seasons. The summer months (December to March) are the most popular, offering stable weather and longer days. In winter (April to October), snow often blankets the final stretch, adding an extra layer of difficulty. Proper footwear and preparation are essential for tackling the terrain, particularly the moraine ascent.

This well-marked trail is suitable for experienced hikers and adventurous beginners alike, as long as they’re prepared for the 7- to 9-hour duration and elevation gain. Remember to pack plenty of water, snacks, and layers to stay comfortable in Patagonia’s unpredictable weather. To help you navigate, check out the detailed route on Komoot below.
