A short but punchy ride, perfect for a morning. From the lodge, you cruise almost on the flat along the Oisans greenway to Allemont, then the road crosses the Verney dam and follows the turquoise lake. At the hamlet of Le Verney, the D43a kicks up straight away: just over 4 km at around 9%, in hairpins, with the lake dropping further and further below. Vaujany has hosted finishes of the Critérium du Dauphiné and the Grande Boucle Féminine. Take a break in the village, at the foot of the cable car, then return the same way.
- 13 Grande Boucle Féminine finishes between 1992 and 2005
- Dauphiné stage finish in 2016 (Froome) and 2022 (Verona)
- 4.2 km averaging 8.9% from Lac du Verney
- Summer

- Closed in winter · reopens in May
In high summer, ride in the morning to avoid the heat. There's a drinking water tap in the centre of Vaujany, near the cable car, and the hairpin descent calls for care, especially when the road is wet.
The greenway is shared with walkers and families, so take it easy. Its route was changed in places after the storms of summer 2024, so check its condition on bike-oisans.com. On the D526 and the D43a, you share the road with cars heading up to the resort. A traffic order from the Isère department regulates the D526 between Allemont and Vaujany (extended in May 2026): check the Isère road information before you set off. No tunnels on the route.
