Col de la Loze, Mountain pass in Savoie, France

Col de la Loze is a mountain saddle at 2,275 metres on the ridge between the Rocher de la Loze and the Sommet des Lanches, on the boundary of Les Allues and Courchevel. Dark grey jagged rock pinnacles rise above snow-covered slopes broken by patches of bare brown ground, and a pale winding track zigzags across the lower slopes. Ski lifts and pistes of the Trois Vallées surround it.

A mountain path up the Col de la Loze was built in 2018 and officially opened on 12 May 2019, when snow still covered the mountain. The 7 km section from 1,673 m was paved for a greenway reserved for cyclists, and motor vehicles are not permitted on the path. The first professional race to climb it was stage 8 of the 2019 Tour de l'Avenir, won by Alexander Evans.

The name comes from Francoprovençal and refers to the slate stones common in this mountain region. Both locals and visitors use this route to experience the alpine landscape and connect the two major ski areas.

The climb from Brides-les-Bains via Méribel is 21.5 km at 7.8%, with the last 6 km alternating between flat sections and walls above 20%. The final 7 km from the Méribel altiport are reserved for cyclists and closed to motor vehicles. The path is paved on both the Courchevel and Méribel sides.

The final six kilometres follow the former access track of a ski lift, with a sequence of flat sections and steep walls and many ramps above 20 percent. The route was not designed for cars, and motor vehicles are not permitted on the path. The 7 km section from 1,673 m was paved in 2019 for a greenway reserved for cyclists, a change contested because of the artificialisation of the mountain space.
