Is the road to Col du Sanetsch paved?

Set high on the western Bernese Alps, at the foot of the Glacier de Tzanfleuron, the road to the summit, also known as Col de Sénin, is totally paved. It’s called Route du Sanetsch. Surrounded by nature and truly exciting landscapes, the road is quite lonely. The road to the summit starts with a little steep through vineyards, but suddenly the environment becomes forest and waterfalls. The last part of the climb features a tunnel, with a length of 800m. It’s extremely dark and there’s just a little bit of light inside. The tunnel – high, in the middle of nowhere – has automatic light sensors. It is long and wet. But it has a few openings for views …. or to hide from cars.

How long is the road to Col du Sanetsch?

Starting at Conthey (in the district of Conthey in the canton of Valais), the road is 25.9 km (16.09 miles) long. Beyond the lake, the road leads to the Lac de Sanetsch, aka Lac de Sénin.
