Grand Crêt d'Eau

Grand Crêt d'Eau is a mountain summit in the French Jura with a height of 1,621 meters and forms a limestone ridge rising above the Valserine Valley. The area is characterized by extensive high pastures that spread gently across the plateau.

The region has been shaped by grazing since centuries, when early inhabitants cleared forests to create pasture lands. This livestock farming molded the landscape and led to the establishment of mountain operations like the Varambon dairy in the early 1800s.

The name comes from the springs and water holes scattered across the landscape, which have long supported shepherds in their work. These natural water sources continue to shape the appearance of the high pasture and reflect the deep connection between people and the land.

The main routes start from Lancrans and require good fitness for a full day outing. Visitors should bring sturdy boots, plenty of water, and protective clothing, as conditions vary with the season.

Natural water holes locally called goyas form through limestone erosion and serve livestock as vital water sources during summer months. These geological features are rare and make the area of interest for nature observers.
