Climb Summary

Cycling Lac Tanay

Ride 11 kilometers gaining 1,027 meters at 9.5% average grade.

This is another of the many Swiss Rhone Valley bike climbs in the greatest climbing area in the world.

Views back to as we begin our climb looking back to Vouvry and the Valley of the Rhone.

Parking lot at kilometer.

From Vouvry we ride up towards Le Grammont, a foreboding mountain in the Chabias Alps subrange of the Alps. Grammont at 2172m is our ultimate destination, but we will have to hike to get there.  We pass through the village of Miex about half way between Vouvry and the parking lot.

The paved road ends at the parking lot at kilometer 9.

The paved road to the parking lot is 9 kilometers at an average grade of 7.8%.  The remaining 2 kilometers is on gravel at an extraordinary 17% average grade.  This section is barely manageable on a road bike.  While it is possible to accomplish this portion of the climb on road bike (with at least 28mm tires), a gravel or mountain bike is recommended.

The biking portion of this route ends at Col de Tanay just below Lac de Tanay.

There are hotels and restaurants at Lac de Tanay.  From here, we hike 5.3 kilometers and 707 meters to the top of Le Grammont.

Now THAT’S steeeeeepppppp!!!!

About 4 kilometers between Lac de Tanay and Grammont peak are manageable on mountain bike.

The last 1.1 kilometers must be hiked and cannot be ridden by any type of bicycle.

Le Grammont is sometimes referred to as Col des Crosses.

There are no better views of Lake Geneva than from the top of Le Grammont.
