Built in 1862, the Dormillouse fortress kept watch over the Ubaye valley from its 2505m altitude. It also controlled the pass and warned of the arrival of the Italians. Dormillouse means “the sleeper”, which is the popular name for the marmot. The oldest inhabitants of the valley tell us that the bored soldiers of Dormillouse used to organize balls to entertain themselves, taking the local girls on mules.

Accessible by hike from the chairlift, Montclar station or Col Bas, it offers breathtaking views over the Ubaye Valley, the Vallée de la Blanche and Lac de Serre-Ponçon. The assurance of an invigorating historical discovery with a magnificent view.
