Emosson - Trophy of the Dams

Emosson Staudamm



The road to the dam is composed of two mountain passes, the Col de la Forclaz and the Col de la Gueulaz, culminating at 1528m and 1965m respectively. The dam region is made famous by dinosaur tracks imprinted into some of the local rocks. The road to the dam had the great honour of hosting a stage finish of the Tour de France on 20 July 2016!

The city of Martigny is the starting point of this long climb of 30 kilometres that will surprise you with its incredibly diverse landscape. You start the day criss-crossing the vineyards before reaching the summit of the Col de la Forclaz in the middle of a larch forest. After a short descent through the town of Trient, you take a right turn off the main road to begin the second climb towards the dam. The ascent takes you through scenery worthy of the great Alpine passes. Feel free to refuel at Finhaut before the final climb to Emosson dam…it’s a tough one.

Turn-by-turn directions

As you pedal through beautifully terraced vineyards, you realize how quickly you are gaining altitude as Martigny becomes smaller and smaller. You leave the grand view of the Rhone Valley once through the Col de la Forclaz (1,528m). Take time to stop and enjoy a delicious fruit tart at the Hotel du Col de la Forclaz, because you still have a long journey ahead. After this well-deserved break, you dive into another valley and pass the village of Trient. A turn off to the right takes you into Finhaut and the start of the second climb. The more you climb, the more the landscape becomes wild and magical. The dam only lets itself be seen at the last moment, once you have reached the summit of the Col de la Guelaz (1,965m). And once there, all of your efforts will be rewarded, as the view over the Mont Blanc and the Aiguilles du Tour is breath-taking. This impressive dam was built between 1969 and 1975, is the second largest dam in Switzerland and the third highest in Valais. When you are on top of the dam in spring, look deep down into the lake and you may see the remains of the Barberine Dam, built in 1925, which was submerged after the Emosson Dam was filled.

Author's recommendation

In autumn, the leaves on the larch trees turn magnificent shades of orange, blueberry leaves turn red, and the landscape becomes worthy of the finest Indian summers! Emotions guaranteed! It is absolutely spectacular!
