Dormillouse, Mountain pasture and alpine cabin in Freissinières, France

Dormillouse is a hamlet of Freissinières in the Hautes-Alpes, set at an average altitude of 1,727 m on the glacial threshold separating the upper Biaysse valley from the lower Freissinières valley. Its houses stand on uneven pasture ground; the main one has pale stone walls, wooden upper sections, a projecting wooden balcony beneath a steep dark gabled roof, and a lower stone wing to the left.

Dormillouse appears as "Dormillosa" in 1401 and "Durmelho" in 1488. From the Middle Ages the hamlet sheltered Waldensians, followers of Pierre Valdo, who faced repression in 1365, 1393 and 1488; in April 1488 the Archbishop of Embrun Jean Bayle sent over six hundred men into the valley. Around 1660 a resident, Claude Baridon, killed the lord of Saint-Disdier over contested alpine pastures.

The buildings showcase slate roofs and wooden balconies attached to barns, displaying construction methods adapted to mountain life in the Hautes-Alpes. These traditional structures shape how the place looks today and reveal how residents worked with their surroundings.

The location is accessible only on foot and requires approximately 40 minutes of walking from the Cascades parking area with about 300 meters of elevation gain. The route is walkable year-round but calls for sturdy footwear and moderate fitness.

The permanent population has shrunk from 62 residents in 1901 to just 1 or 2 people today, yet a working mountain refuge operates in the former school building. This refuge now serves as a welcome stop for hikers exploring this isolated high-altitude settlement.
