Patagonia Expeditions Since 1985

Tailor made trekking and expeditions in Los Glaciares National Park

BORN IN EL CHALTÉN · SINCE 1985

Before El Chaltén became one of Patagonia's most celebrated trekking destinations, Alberto del Castillo was already exploring these valleys and helping open routes that would become part of the region's mountaineering history.In 1995, he founded Fitz Roy Expediciones to share the mountains he had come to know through years of guiding and exploration.Today, more than thirty years later, we continue leading small groups across the Fitz Roy Massif, the Huemul Circuit and some of Patagonia's most remarkable mountain landscapes, following the same local knowledge and mountain philosophy that shaped our very first expeditions.

Campamento Poincenot: A Night Beneath Mount Fitz Roy

Camping in Los Glaciares National Park

Campamento Poincenot is the traditional base camp for hikers and climbers exploring Laguna de los Tres and the Fitz Roy Massif in Los Glaciares National Park. Surrounded by native lenga forest at the foot of Mount Fitz Roy, it offers the unique opportunity to experience Patagonia after the day hikers have returned to El Chaltén.

From here, the final ascent to Laguna de los Tres begins before sunrise, allowing us to reach one of Patagonia’s most iconic viewpoints as the first light illuminates the granite peaks. During our guided treks, Fitz Roy Expediciones provides all camping equipment while our local guides take care of the logistics and safety throughout the journey.
