This is a an excellent alpine cross country trail in a part of the planet where downhill trails predominate. It's follows back roads, mountain trails and singletrack across the border between France and Switzerland. It's not a purpose built mountain bike trail.
There scenery is stunning - be sure to go on a fine clear day. There are a number of ski lifts you can use to reduce the uphill grunting. You will need a good map or a guide to find the way.
