Col de Tanay

A brutally steep (35%) road to Col de Tanay

Col de Tanay is a high mountain pass at an elevation of 1.440m (4,724ft) above the sea level, located in Valais, Switzerland. The road to the pass is extremely steep, with sections up to 35%.

Tucked away in the Chablais Alps, the narrow, barely used road to the summit, also known as Col de Taney, is totally paved. At the beginning is a big, fairly quiet, well-surfaced road, with plenty of hairpins but suddenly, the surface of the road is in very poor conditions. This road is truly crazy-steep.

Starting from the village of Vouvry, the ascent is 10.4km (6,46 miles) long. The average slope is over the 20,3 %. Beyond the pass, a little trail leads to the Tanay lake. This part of the road is closed to vehicles. The lake is a little past and below the col. It’s small, surrounded by quite a few chalets, and a restaurant.
