Cordillera Blanca Traverse (CBT)

The significant Andean high-route. The Cordillera Blanca Traverse (CBT) is a 400km long-distance epic that navigates the sheer walls and glacial valleys of the world's highest tropical mountain range. Conceceived as a continuous high-route, it crosses over 20 passes above 4,400m, reaching a maximum altitude of 5,200m. This is not just a hike; it is a high-altitude odyssey that links famous sectors like Santa Cruz and Alpamayo with completely unknown, pristine glacial valleys. Trekkers move through a landscape of more than 700 glaciers and 300 emerald lakes, constantly shadowed by 6,000m giants like Huascarán and Artesonraju (the 'Paramount Pictures' mountain).

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.
