The Finsteraarhorn Hut (German: Finsteraarhornhütte) is a mountain hut of the Swiss Alpine Club, located north of Fieschertal in the canton of Valais . It lies at a height of 3,048 metres (10,000 ft) above sea level at the southern foot of the Finsteraarhorn, the highest peak of the Bernese Alps . The hut overlooks the upper basin of the Fiescher Glacier , which is among the largest of the range. It is located a few kilometres east of the Grünhornlücke.

The hut is set in a very remote area and is accessible only to mountaineers as all accesses involve glacier crossing. The shortest access is from the Jungfraujoch train station (6 hours).
