Le Roc de Tougne

There are hikes that follow a path, and others that follow a border. The Roc de Tougne is one of the latter: a ridge line, literally on the edge, between the Belleville Valley and the Méribel Valley. On one side, the familiar alpine pastures. On the other, a completely different landscape unfolds. Between the two, a high-altitude trail where the view stretches far—all the way to Mont Blanc and the Vanoise glaciers, which seem almost within reach.

An extraordinary atmosphere

After gaining altitude by cable car, the hike leads towards Lac des Allamands, a mirror of water nestled in the heart of the mountain, before venturing into wilder terrain, far from the marked trails. Here, the atmosphere changes: silence settles in, the view opens up, and you become aware that you are truly on a border—the one that separates two valleys, two mountain worlds that speak to each other without ever touching.

One of the most beautiful panoramas in the valley

The ridge trail offers a succession of breathtaking viewpoints: Mont Blanc dominating the horizon, the Vanoise glaciers shimmering in the distance, and below you, the two valleys unfolding on either side of the Roc de Tougne. A rare panorama, commensurate with the effort and commitment of this hike.

This outing is for hikers eager to venture off the beaten path, comfortable on challenging terrain and sometimes off-trail.
