Mount Fitz Roy (Cerro Fitz Roy)

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.

This is the most accessible high-alpine experience in the Picos de Europa. The route begins with a dramatic 753m vertical ascent via the Fuente Dé cable car to the 'El Cable' mountain station. From this stark limestone plateau at 1,834m, the trail descends through the 'Puertos de Áliva'—vast, rolling green meadows that feel like the Swiss Alps. The path winds past isolated mountain hotels and through peaceful beech and oak forests before returning to the valley floor at Fuente Dé.
