Tschingelhorn, Alpine summit in Bernese Alps, Switzerland.

Tschingelhorn is a 3,555 m summit on the border between the Swiss cantons of Bern and Valais, between the Lauterbrunnental and Lötschental valleys. Its western neighbour, the Klein Tschingelhorn (3,494 m), marks the tripoint of the Kandertal, Lauterbrunnental and Lötschental valleys. The two summits are linked by a traverse graded III.

The first ascent was made on 6 September 1865 by Heinrich Feuz, W. H. Hawker, and Ulrich and Christian Lauener. The mountain gave its name to Tschingel, a dog given to W. A. B. Coolidge by guide Christian Almer in 1868; she made eleven first ascents and was nominated, but not accepted, as an honorary member of the Alpine Club because of her gender.

The mountain lies within the Jungfrau-Aletsch-Bietschhorn UNESCO World Natural Heritage site. Its name passed to Tschingel, the dog given to climber W. A. B. Coolidge by guide Christian Almer in 1868; she accompanied him on many Alpine routes until her death in 1879.

Climbers depart from a mountain hut and must navigate across glaciers with an early start to find safer snow. Weather conditions change quickly at this elevation, so timing and preparation are critical for a successful ascent.

W. A. B. Coolidge received the dog Tschingel as a gift from guide Christian Almer in 1868, and she was named after this mountain. She made eleven first ascents and completed 66 grandes courses, but the Alpine Club nominated her without accepting her as an honorary member because of her gender.
