Chalet Refuge de Lognan

Refuge de Lognan sits at 2,032m in the Chamonix valley, accessed via the Mer de Glace area. From Montenvers (1,913m), the hut is a 2-hour hike northwest through mixed terrain—mostly straightforward but with rocky sections that need attention. The route crosses the Mer de Glace glacier area; conditions change seasonally, so check conditions before you go. From Le Fayet-Saint-Gervais via the Montenvers train and then on foot, allow 3 hours total from the valley floor.
The refuge is a modest chalet operation with capacity for around 30 people. It serves as a working base for acclimatisation walks, training climbs on Mont Blanc, and routes toward the Aiguilles Rouges. Half and full board are available. The hut has basic dormitory bedding, a small dining room, and a wood stove. Water comes from a spring. The season runs late June through early September, depending on snow cover and access conditions.
Book at least one month ahead for July and August. Contact the guardian directly or through local alpinism organisations. The hut is managed independently, not by FFCAM. Summer weekends fill quickly, so weekday visits offer better availability. Bring a sleeping bag—linen is not always provided.
