There’s nothing quite like an overnight stay in a mountain shelter. Staying in the mountains once the sun has gone down is an intensely peaceful experience…
The hike up to the shelters of the Alpe de Villar d’Arène (420 m difference in altitude) are “family friendly“, or you can try the “sporty” version in Ecrins National Park (1,240 m and 1,430 m difference in altitude), but it doesn’t require any mountaineering techniques.
So make sure you choose your mountain shelter wisely, depending on your level of fitness.
