To the north and beyond Eigen, the Alp flows through the village Trachslau and further through the town of Einsiedeln some 7 km (4.3 mi) beyond.

Hiking trails, only passable on foot in summer, cross both the Haggenegg and the Holzegg to the town of Schwyz.

A cable car also links Brunni with the summit of the Holzegg, operating in both summer and winter.
