 However, most of the municipality's area comprises sparsely inhabited high mountain landscape and is heavily glaciated, including most of the Aletsch glacier and its tributary glaciers, together with the whole of the Fiescher glacier.The mountains of the Jungfrau, Mönch, Fiescherhorn, Agassizhorn, Finsteraarhorn, Oberaarhorn, Wasenhorn, Grunhorn, Wannenhorn, Eggishorn, Aletschhorn, Mittaghorn and Gletscherhorn are all either within or on the boundary of the municipality, as is the Märjelen lake.The Jungfraujoch, with the Top of Europe tourist attraction, lies just inside the northern boundary of the municipality, but access is exclusively from communities to the north.
