The tiny spot between Klosters Platz and Monbiel is home to the Ehrat salmon farm, a family business processing Norwegian Salmo Salar. The Zwergenweg (Dwarf Trail), with Purzel and his friends, is full of surprises, great fun for all ages and easily reached from Aeuja. In winter, a superb sledge run leads down from Guggerstein to Aeuja but the start can only be reached on foot. Sledge rental is not available.
