Refuge de Plan Sec

Refuge de Plan Sec sits at 2,331m in the Chaîne de la Vanoise, accessed most commonly from the Vallée de la Tarentaise. The main approach climbs from Champagny-en-Vanoise village (1,248m), taking 4–5 hours on a well-marked trail. The route gains 1,083m steadily through alpine meadow and larch forest before reaching open terrain near the hut. In summer, alternative approaches exist from the Parc National de la Vanoise side via longer valleys. Winter access is not practical.
The refuge operates as a staffed hut run under FFCAM guidelines, accommodating around 35 people in dormitory beds. The guardian provides evening meals and packed lunches; bring your own sleeping bag unless hiring blankets. Water comes from a spring near the hut—reliable in summer and autumn. The hut sits on the Vanoise main ridge, offering access to neighbouring peaks and multiple onward trail options. Opening runs from mid-June to late September; dates depend on snow melt and guardian availability.
Book 8–10 weeks ahead for July and August weekends; the hut fills regularly during peak season. Contact the hut directly by phone or email through the FFCAM directory, or call Champagny-en-Vanoise town office for current contact details. July brings the heaviest traffic. June and September offer quieter conditions and good weather odds. Arrive early in the day if walking up the same day, as the approach takes most of daylight in winter's shorter hours.
