Details:
This family-friendly hike takes you to the heart of the Taillefer plateau, with its landscapes reminiscent of the Scottish Highlands. In contrast, the surrounding peaks — the Taillefer, Rocher Culasson, and Grand Galbert — create a strikingly alpine backdrop, while distant views open up onto the Oisans mountain range.
