Castaño Overa Glacier

Castaño Overa Glacier descends from Mount Tronador's slopes at roughly 1,900 meters elevation, displaying deep blue crevasses and layered ice formations shaped by time. The surface shows rough textures and steep drops created by the slow movement and melting of ice over many years.

The glacier formed during ancient ice ages and has shaped Mount Tronador's landscape for thousands of years. Since the 1900s it has shrunk significantly, with its size today much smaller than in previous centuries.

Local mountain guides from AAGM lead expeditions to the glacier, sharing their knowledge of glacial formations and Patagonian ecosystems with visitors.

The hike to reach it takes about four hours from Pampa Linda, passing through forests and rocky terrain where good boots are essential. The Otto Meiling refuge along the route provides shelter and serves as a good place to rest before or after the main walk.

Visitors can walk across the ice surface using special equipment while experiencing the stark contrast between white ice and dark mountain peaks. This close encounter reveals the raw beauty of the formations that appear distant from typical viewing spots.
