At the summit of the Großer Osser on the Bavarian side of the border is the mountain hut of Haus Willmann, which is owned by the Bavarian Forest Club, which is managed during the summer months and also offers overnight accommodation. The pointed shape of the summit on the German side of the border means that the last 50 vertical metres or so involve an easy climb. Because the Osser is one of the best viewing mountains in the whole of the Bavarian Forest, it receives large numbers of German and Czech visitors on summer weekends, both hikers and tourists. From the summit cross there is an extensive view into Czechia over the Bohemian Forest, as well as to the nearly summit of the Arber and, in good visibility, even as far as the Alps.
