Mittelhorn, Mountain summit in Bern, Switzerland

The Mittelhorn is a 3,702 m peak east of Grindelwald in the Bernese Alps, the highest of the Wetterhörner chain together with the Wetterhorn (3,690 m) and Rosenhorn (3,689 m). Its normal route leaves the Gleckstein Hut over the Willsgrätli or the Dossenhütte over the Rosenlaui Glacier and Wellhornsattel (3,195 m) to the Wettersattel (3,478 m), then follows the west ridge to the summit.

Swiss climbers began ascending the peak regularly during the 1800s as Alpine mountaineering grew as a pursuit. These early expeditions helped establish climbing traditions in the Bernese region.

The name combines Middle High German 'mittel' (middle) and 'horn' (peak), marking it as the central summit of the Wetterhörner chain. The three peaks are named Wetterhorn, Mittelhorn and Rosenhorn; seen from Grindelwald the Wetterhorn appears most prominent, so it is the one usually climbed.

Reaching the summit requires solid climbing skills and proper Alpine equipment such as ropes and ice axes. Visitors should hire a local guide and plan their attempt for favorable weather conditions.

The Mittelhorn is the nearest higher peak to Gunnbjørn Fjeld, Greenland's highest summit, more than 3,200 km away. Its 3,702 m top makes it the highest of the three Wetterhörner, above the Wetterhorn (3,690 m) and Rosenhorn (3,689 m).
