This route consists of a climb to Mauvoisin dam from Le Châble and offers a view of Mont Rogneux, the Rosablanche and the Grand Combin.
The starting point is situated at the bridge that straddles the Dranse river and the railway line near Le Châble. There are no major slopes on the Route de Mauvoisin until Le Fregnoley, at which point it becomes steeper and more uneven, with a few level stretches and gentle downhill sections punctuating the climb towards Fionnay reservoir lake and the journey through Bonatchiesse hamlet. You’ll pass through a number of short galleries along the route, as well as crossing several wooden bridges over waterways. The valley grows wilder and narrower as the kilometres roll on, allowing you to discover an unspoilt natural landscape and stunning panoramic views. Cyclists can admire various peaks during the climb, including Mont Rogneux, the Rosablanche and the Grand Combin (4,314 m.a.s.l). Once you reach the dam, it's worth taking a look at Mauvoisin lake (1,961 m.a.s.l). The official finishing point of the route is situated near the restaurant at 1,841 metres in altitude.
Admire the complexity of the dam’s structural elements as you pass by various installations over the course of the climb.
