A granite-and-reservoir pass linking the Bernese and Valais Alps.

The Grimsel Pass at 2,164 m drops between Innertkirchen and Gletsch through a stark granite landscape strung with dam reservoirs. Wide, fast hairpins and dramatic scenery; mind the cyclists, the dam traffic, and quick changes in mountain weather.

Granite is the whole story here: bare grey slabs and steel-blue reservoirs, a clean ladder of hairpins, and air so thin it’s just rock, water and sky.
