Regenboldshorn
The Regenboldshorn is a mountain of the Bernese Alps, located between Lenk and Adelboden in the canton of Bern. It lies south of the Hahnenmoos Pass, at the foot of the Ammertenspitz.
The summit of the Regenboldshorn can be reached via marked trails from all sides of the mountain, except for the northeast side, which forms a steep limestone cliff. A chair lift connects Geisbüel to a lower summit on the east named Bummeregrat.
