Aletscharena

High above the Rhone Valley in the Valais Alps lies the Aletsch Arena, home to the most powerful ice stream in the Alps. This UNESCO World Heritage region is defined by the Great Aletsch Glacier, a 23-kilometer river of ice that carves a spectacular path through the mountains. With its car-free plateaus and panoramic "sun terraces," this is a landscape of raw, prehistoric beauty and high-altitude serenity.
