Rocher Blanc

Rocher Blanc is a mountain summit in the Belledonne range, located in the Isère department of southeastern France. The peak rises to 2,928 meters and displays distinctive light-colored gneiss rock formations characteristic of this alpine ridge.

The peak was first documented ascended in the late 1800s and quickly became established as a destination for mountaineers. This early climbing history helped establish its reputation within alpine circles.

The mountain serves as a center for alpine activities, where local climbing communities organize expeditions and share mountaineering knowledge throughout the seasons.

Multiple routes ascend from Fond-de-France to reach the summit, with the most favorable climbing season running from late spring through early autumn. The trails become more manageable after snow melts and terrain conditions stabilize.

The peak ranks as the third highest in the Belledonne chain, exceeding nearby Croix de Belledonne by just 2 meters. From its heights, visitors can view the Sept-Laux lakes below, a vista that reveals multiple alpine bodies of water in a single view.
