Enjoy a globally unique experience on the largest glacier in the Alps. The adventure trail takes you along a marked footpath to a huge crevasse, crossed on a suspension bridge. At around 22 kilometres long, the Great Aletsch Glacier is the heart of the Jungfrau-Aletsch protected area, a UNESCO World Heritage Site in the Swiss Alps.
