Crêt de Châtillon, Mountain summit in Viuz-la-Chiésaz, France

Crêt de Châtillon is a summit in the commune of Viuz-la-Chiésaz, Savoie, rising to about 1,700 m on a hogback ridge of the Bauges massif. Its slopes fall away steeply on both sides, and the summit opens onto views across the surrounding alpine terrain.

The 1998 Tour de France was due to cross the Crêt de Châtillon, but riders stopped on the road and refused to continue in protest against anti-doping controls and police searches of team vehicles. The stage was annulled, and the climb did not feature in that year's race.

The summit is the highest point of the Montagne de la Chambotte ridge above Viuz-la-Chiésaz, and the crossing of the ridge is used by walkers and paragliders who launch from the slopes. The name Châtillon refers to the old castle site on the ridge, of which only traces remain.

Multiple routes climb the mountain, including walking and cycling paths starting from different surrounding villages. Visitors should bring proper gear and allow adequate time, as the routes vary in difficulty depending on the starting point.

The summit can be accessed through different climbing routes, each presenting distinct technical challenges for cyclists and hikers. Starting from different points like Col de Leschaux or Quintal creates varied experiences with different levels of difficulty.
