[Closed summer 2026] Galerie Hydraulica

This interpretation centre, with its scenography, lets you discover all the secrets of hydroelectricity and its history, which have left their mark on the Bozel valley.
Surrounded by the glaciers of the Vanoise, Le Planay has witnessed a human and industrial adventure for almost a century. At the foot of one of the world's largest penstocks, which collects water from the glaciers, the Galerie Hydraulica plunges you into the world of hydroelectricity: how it works, its industrial applications and its impact on local life. It's an interactive visit for all the family!
