The Geisshorn is a mountain of the Bernese Alps, overlooking the Aletsch Glacier in the canton of Valais. Together with its Northeast-Summit Sattelhorn (3724 m), it appears as a Doublepeak. Northwest of the Sattelhorn, the slightly lower ridge of the Vorderes Geisshorn (3632 m) leads to the south-ridge of the Aletschhorn.
