Shelter Rajon

Abri Rajon sits at 2,645m on the eastern flank of Pic de la Grave in the Hautes-Alpes, deep in Parc National des Écrins. Reach it from the Vallée du Valgaudemar via the hamlet of Saint-Firmin. The approach takes 4–5 hours on foot, gaining roughly 1,500m through alpine pasture and scree. This is a serious mountain walk, not a day hike from the valley floor. You'll cross streams and navigate exposed terrain in afternoon thunderstorm season (June–September).
This is a basic refuge—call it a shelter—with 3 beds and minimal facilities. There is no warden, no meals, and no running water. Bring your own food, fuel stove, and sleeping bag. You'll find a basic roof, walls, and a log of previous visitors. Winter access is possible for experienced winter mountaineers only; snow and avalanche risk dominate December–April. The shelter sits in a zone of serious mountain weather and isolation.
Contact the FFCAM Vallée du Valgaudemar or check with the mairie in Saint-Firmin before visiting. Do not assume beds are available—plan for a bivy or carry a tent as backup. Tell someone in the valley where you're going and when you'll return. This is a refuge for winter accents and experienced mountain users, not beginners or casual hikers.
