Oeschinenhorn, Mountain summit in Bernese Alps, Switzerland

The Oeschinenhorn is a 3,486 m mountain in the Bernese Alps and the westernmost summit of the Blüemlisalp main ridge. To the east the ridge continues with the Blüemlisalphorn, the Wyssen Frau and the Morgenhorn; to the west the Oeschinenjoch (3,170 m) links it to the Fründenhorn. Its south side drops in a steep rock wall to the Kanderfirn, while the northwest ridge runs toward Lake Oeschinen between the Vorderer Blüemlisalp Glacier and the Oeschinen Glacier.

This peak was first explored by mountaineers in the 19th century as part of the broader discovery of the Blüemlisalp massif. The construction of the Fründenhütte mountain shelter established a key stopping point that helped make ascents more feasible for later climbers.

The Oeschinenhorn is rarely climbed as a destination in itself; most parties reach it as part of a traverse. From the summit, the usual continuation crosses the southwest ridge to the Blüemlisalphorn, a route rated ZS with climbing up to grade III. The normal ascent follows the northwest ridge, which lies between the Vorderer Blüemlisalp glacier to the east and the Oeschinen glacier to the west.

The approach starts from the village of Kandersteg in the valley, where hikers can reach the trailhead on foot or by cable car. The climb demands rock climbing skills and good weather, so going with a local mountain guide or experienced group is strongly advised.

The Oeschinenhorn is rarely climbed as a destination in itself: most parties reach it via the northwest ridge from the Fründenhütte (2,562 m) and then continue over the southwest ridge to the Blüemlisalphorn, a combined route rated ZS, grade III. The northwest ridge runs between the Vorderer Blüemlisalp glacier to the east and the Oeschinen glacier to the west.
