At 1,547 in altitude, the Refuge de Rosuel is also known as the “refuge-porte” (gateway shelter) of the Vanoise National Park because it is both close to the heart of the Park and accessible via the road. Designed in 1971 by architect Christian Durupt, it features a wave-shaped roof set into the slope so as not to be buried under potential avalanches. In 2010, major upgrades were made to improve its comfort and brightness. The refuge is only looked after and open in the summer period. The ground floor is a reception and information point for the National Park.
