Though gangly, it's nicer than most dorms, with sublime Los Cuernos views in all rooms. Its year-round presence is a godsend to cold, wet winter hikers, though meals are not available in winter (May to September). There’s on-site camping, a kiosk with basic kitchen provisions and a more deluxe version of camping in domes.
Between Lago Grey and Valle Francés, it’s a day hike from either and also accessible by ferry across Lago Pehoé. Advance reservations required.
