Arnenhorn

Arnenhorn is a 2211-meter mountain summit in the Bernese Alps positioned between the cantons of Vaud and Bern. Limestone cliffs rise steeply across its upper sections while gentler alpine meadows cover the lower slopes.

The mountain has served as a boundary between two cantons since 1803, when Vaud became independent from Bernese control. This border reflected the broader territorial reorganization that reshaped Switzerland during that era.

The area around this summit has long been shaped by Alpine farming traditions visible in the mountain meadows and pastoral landscape. Seasonal use of high pastures remains an important part of how people interact with this terrain.

Marked hiking trails ascend from Arnensee lake to the summit, requiring roughly four hours during summer. The route passes through water sources and includes spots to rest along the way.

The eastern rock face functions like a natural sound reflector, producing distinct echoes that bounce back across the valley below. This acoustic quirk often surprises hikers exploring the upper sections.
