Widderfeld Stock, Mountain summit in Obwalden, Switzerland

Widderfeld Stock is a 2351 m mountain on the border of Obwalden and Nidwalden, between the Melchtal and Engelberg valleys. Its summit is a curved ridge whose highest point is hard to identify, marked by a small masonry pyramid. The Alp Widderfeld hut stands at 2257 m just southwest of the ridge.

The peak has long served as a natural boundary between the cantons of Nidwalden and Obwalden. This geographical division has remained an important reference point for the surrounding valleys across centuries.

The name Widderfeld comes from "Widder", a male breeding sheep, because the slopes served as pasture for sheep. The Alp Widderfeld hut stands at 2257 m, among the highest alps in the region, and the lower Alp Gruobi at 2024 m holds a memorial stone to two gamekeepers shot by Nidwalden poachers on 14 October 1899.

Access is possible from multiple valley sides, with routes that are well-marked and offer varying levels of difficulty. Visitors should be prepared for changing weather conditions, especially when moving between different valley areas.

The summit ridge is a curved crest where the highest point is hard to pick out; a small masonry pyramid marks it. Just southwest, at 2257 m, the Alp Widderfeld hut is among the highest alpine pastures in the country.
