Fründenhorn, Mountain summit in the Bernese Alps, Bern, Switzerland.

The Fründenhorn is a 3,368 m mountain in the Bernese Alps, south of Lake Oeschinen near Kandersteg. To the west it connects via the Fründenjoch (2,983 m) to the Doldenhorn, and to the east via the Oeschinenjoch (3,170 m) to the Oeschinenhorn. Its south side drops in steep rock walls to the Kanderfirn, while the Fründen and Oeschinen glaciers descend northward toward the lake.

The sources record no first-ascent date for the Fründenhorn, so the 1862 claim is unsupported. What they do document is the mountain's setting: the 3,368 m summit stands between the Fründenjoch (2,983 m) and the Oeschinenjoch (3,170 m), with the Fründen and Oeschinen glaciers descending north toward Lake Oeschinen. The Fründenhütte at 2,562 m, below the Fründengletscher, has long served as the starting point for climbs.

The name Fründenhorn comes from the Fründen area, and the Fründenjoch (2,983 m) and Fründengletscher below the summit carry it too. The Fründenhütte at 2,562 m, beneath the northwest flank, serves as the starting point for the normal route over the northwest ridge, a climb rated WS+.

The usual route starts at the Fründenhütte (2,562 m) below the Fründengletscher and leads over the glacier to the northwest ridge, then up a firn slope to the summit (WS+). The southwest ridge from the Fründenjoch is a bolted rock climb up to grade IV, A0. Both approaches cross glacier terrain.

The Fründenhorn is climbed by its northwest ridge, reached from the Fründenhütte at 2,562 m via the Fründen Glacier; the route is rated WS+ and ends on a firn ridge. A bolted rock route over the southwest ridge, starting from the Fründenjoch (2,983 m), reaches climbing difficulty IV, A0.
