Chalet de Montartier Dessous

Chalet de Montartier Dessous sits at 1,520m in the Isère Alps, serving as a base for routes into the Parc National des Écrins. The hut is accessible from the Valgaudemar valley via a marked trail that climbs roughly 2 hours from the hamlet of Saint-Julien-en-Valgaudemar. Most hikers approach from the west, making it a natural waypoint on treks between the valley floor and higher alpine terrain. Winter access is possible but requires mountain skills and good snow conditions.
The chalet operates year-round with capacity for around 20 people in basic dormitory accommodation. The FFCAM manages the hut. Meals focus on hearty mountain fare; half-board and full-board options are available. Water comes from a reliable spring. The facilities are functional rather than comfortable—expect an old-school alpine refuge with no heating in unoccupied rooms and simple washing facilities. Summer (June to September) is the main season, though autumn brings fewer crowds and reliable weather.
Book at least 2–3 months ahead for July and August weekends. Contact the FFCAM directly or check their website for current rates and opening dates, as the chalet sometimes closes for maintenance in shoulder seasons. Solo hikers and small groups often find availability mid-week. The hut can usually accommodate same-day arrivals outside peak weeks, but don't rely on it.
