On the east side of the Chamonix valley, the Les Mottets hiking route is a 5km switchedback doubletrack from Les Planards in Chamonix (1000m) to the Les Mottets summit (1913m). Situated at Les Planards in Chamonix, a 4x4 track rises directly up the winter piste next to the luge track. Follow the 4x4 track as far as it goes. The last 200m is unridable but the view of the Mer de Glace is definitely worth it.
Overall, Les Mottets is the 12th most popular hiking trail of all 14 hikes in France.
