The trek to Laguna de los Tres is one of the primary day activities in Los Glaciares National Park, providing a close-perspective view of the granite massif of Mount Fitz Roy (3,405m). The route follows an out-and-back trail through mixed forest and glaciated valleys, passing the Piedras Blancas viewpoint before the final ascent. The journey is defined by a significant transition from the low-lying valley floor to the high-alpine environment of the lagoon, which sits directly below the main peaks.
Mission Directive / X-Factor
“The Sunrise Alpenglow. Reaching the lagoon at dawn allows for observation of the 'alpenglow' phenomenon, where the first direct sunlight causes the granite spires to appear bright orange. This visual experience, combined with the proximity to the hanging glaciers of the Adela and Fitz Roy ranges, is a central objective for many trekkers in the region.”
Hazard Assessment
Strong winds are common in the Fitz Roy massif, particularly in the afternoon. Gusts can make the final ascent unstable in exposed conditions.
MITIGATION: Check current wind forecasts in El Chaltén before departure. Avoid the final ascent during high-wind warnings or unstable weather conditions. Maintain stable footing and use trekking poles.
The final descent is steep and rocky, which can strain knees and ankles on the return journey.
MITIGATION: Utilize trekking poles for joint support; descend with controlled movements; ensure footwear provides adequate traction and ankle stability.
