The municipality of St-Léonard, where the climb to the Tseuzier dam begins, is home to the largest underground lake in Europe. The first kilometres wind through the vineyards of the Combe de Voos, where you climb little by little above the valley until the village of Botyre. The road then climbs to Liène on a mostly steady incline through a forest, with a few bends where the trees clear and you can admire the view over the high peaks on the opposite side of the Rhone valley. The climb continues with a few switchbacks towards Tseuzier Lake where you can see the reflection of the peaks that surround it.

Turn-by-turn directions

The itinerary begins at Bramois and takes you to St-Léonard, at the other side of the valley. Leaving this village, you first cross exceptional vineyards dotted here and there by fig trees and rose bushes. It is not rare to hear cicadas singing in the summer, giving these first few kilometres of climbing the sensation of being in Provence. From Botyre, the landscape changes, becoming more mountainous as the road gradually becomes narrower. Take advantage of the panoramic view over the highest peaks of the Valais as the road gradually climbs to one of the few dams located on the right bank of the Rhone river. On arriving at the summit, the clear waters of Tseuzier Lake are sufficient to comfort even the most exhausted cyclist, and the view over the Rawil Pass that we can see at the end of the valley is enough to forget the all the effort spent climbing from Bramois.
