Chalet du Sac
3.6About
Chalet du Sac sits at 1,381m in the Chaîne des Aravis, a limestone massif in Haute-Savoie that separates the Aravis and Borne valleys. The hut works as a base for day walks across the range or as an overnight stop on the GR96 long-distance trail. Access takes 2–2.5 hours on foot from Montmin village, climbing steadily through mixed forest before opening into alpine pasture. In winter, approach is only practical on skis or snowshoes; the access track is not groomed.
Chalet du Sac is small and informal, sleeping 7 people across two rooms. It runs as a refuge d'étape rather than a staffed mountain hut, so you cook for yourself using a gas stove. Expect basic shelter: a wood burner for warmth, but no flush toilets or running water beyond a tap outside. The hut stays open year-round, though winter visits need reliable mountain experience and self-sufficiency. Space is tight, so groups should plan accordingly.
Book in advance through the local FFCAM section or contact the keeper directly. The hut fills quickly in July and August. Bring a stove fuel canister if your camping stove needs it, and carry sufficient food. Water is reliable from the external tap. Winter access requires proper gear and navigation skills—don't attempt it in poor visibility or instability.
