With an unbelievable 27 billion tons of ice, the Large Aletsch Glacier is part of the Unesco World Heritage Site and is the Alps' mightiest ice flow. It is easily accessible and is ideally situated for extensive hikes, winter sports and special nature excursions. The entire region is a habitat for many rare animal and plant species. Innumerable vantage points offer a good view of the glacier, such as the Bettmerhorn above Bettmeralp. Eggishorn, which can also be reached via cable car from Fiesch via cable car, offers a magnificent view of the winding upper part of the large glacier. Beautiful Lake Märjelen, which is fed by glacial meltwater, lies at the base of the ice flow.
