Roseg Glacier

Roseg Glacier is a glacier in the Bernina Range that stretches for several kilometers through the Val Roseg valley. The ice sheet reaches high elevations and creates a striking white expanse between the surrounding peaks.

The glacier has been systematically measured since the 19th century and shows continuous retreat from that period onward. These changes reflect long-term climate trends affecting the Swiss Alps.

The glacier holds the status of Ramsar Wetland site since 2005, contributing to Switzerland's environmental conservation efforts and scientific research programs.

The glacier is accessible from Pontresina via marked hiking trails that lead to various viewpoints. The best time to visit is during warmer months when the trails are clearer of snow.

Beneath the ice surface runs a complex network of water channels that transports meltwater through a natural underground system. These hidden passages play an important role in how the glacier manages its water flow.
