Col de la Gueulaz – Legendary Mountain Passes

Radfahrer im Finhaut


There are about eleven kilometres between Le Châtelard and the Col de la Gueulaz at a height of 1,965m. Made famous by its dinosaur tracks, this pass located at Emosson Dam had the honour of hosting the Tour de France on July 20, 2016.

The village of Le Châtelard on the border with France is the starting point for the ascension of the Col de la Gueulaz. After several hundred metres on the route de la Forclaz, this itinerary takes a left towards Finhaut. As you are climbing, you discover impressive mountain scenery worthy of the great Alpine passes. Feel free to refuel in the village of Finhaut, as the last part of the climb that brings you to the Emosson Dam will require some muscle. The summit is located at the arrival location of a stage of the 2016 Tour de France, and the restaurant at the dam will replenish you while offering a view that will take your breath away!

Turn-by-turn directions

From Le Châtelard to the Emosson Dam, the Col de la Gueulaz is poised to become a must-do pass for any cycling fan, as it was the arrival point of the Bern-Emosson stage of the 2016 Tour de France. The more you climb, the more the scenery becomes pristine and magical! Until the last moment, the dam remains hidden, and you won’t see it until you have conquered the Col de la Gueulaz at 1,965m. And there all of your efforts will be compensated, with the view of the Mont Blanc, the Aiguilles du Tour, and this impressive dam constructed from 1969 to 1975, the second largest dam in Switzerland, and the third highest in Valais. When you are on top of the dam in spring, look deep into the lake and you may see the remnants of the Barberine Dam… Constructed in 1925, it was engulfed by the Emosson Dam when it was filled...
