Rifugio Nacamuli Al Col Collon

Rifugio Nacamuli sits at 2,818m on Col Collon, the border pass between Italy's Val d'Aosta and Switzerland's Valais. The hut anchors access to Gran Paradiso (4,061m) and Mont Rosa approaches. Reach it from Lillianes in the Val d'Ayas via a well-marked trail gaining 1,200m over roughly 4 hours. The route climbs steadily through pasture and scree, with water sources reliable until late summer. In winter, the approach requires mountaineering skills.
The rifugio holds 70 beds across multiple rooms. Meals are served in the dining room—expect simple, fuel-focused food rather than variety. The kitchen provides packed lunches on request. Hot water and basic washing facilities work reliably. The hut operates year-round, though winter visits need advance warning so staff can prepare. Mobile signal is poor but not absent.
Book directly by phone well ahead for July and August; expect crowds during the Gran Paradiso season. June, September, and early October offer better availability. Winter ascents need 2–3 weeks' notice. The hut sits on a recognised alpinist's route, so climbers targeting Gran Paradiso or Mont Rosa should expect busy nights. Confirm your arrival time when booking to ensure the kitchen prepares enough food.
