The Roc de Chère is a small mountain, culminating at a modest 651 metres (2,136 ft), which was formed by a quaternary glacier from the south.

This significance is not entirely understood, hence Chère became a proper noun and "Roc" (modern French for rock) was added and is not considered a pleonastic reinforcement.

Among them they include: Glaciers have left a peat bog where one can find Drosera, mud sedge (Carex limosa), and the northern emerald (Somatochlora arctica), an insect in the order of Odonata.

In a canyon hidden under the forest, one can find plants that are able to grow up to elevations of 2,000 metres (6,600 ft) (Rhododendron ferrugineum, Lycopode sélagine).

On Sunday 21 June 2009 at 2:30 in the morning, three young men were killed and two seriously injured after their motor boat ran into a Roc de Chère cliff at full speed after returning from a nightclub in Annecy.
