“A long, steep, rugged descent on singletrack and ancient stone road through the Val d'Ayasse Valley.”

This is your reward for climbing the Champorcher to Dondenaz Forest Road
. Well, hopefully you also visited Lago Miserin while you were up there and/or came through the Finestra di Champorcher pass.
In any case, this route starts at the crossroads in Dondenaz just north of the Torrente Ayasse (Creek). A narrow singletrack through a pasture parallels (and joins for a short distance) the Champorcher to Dondenaz Forest Road
. You'll likely encounter livestock (the cows are docile but give them appropriate space), and you'll have to open and close electric fences behind you.
After 1.5 miles, the trail transitions to a doubletrack, and you'll enter a three-way intersection near several buildings. Continue straight to head down towards a bridge over the Torrente Ayasse.
As the doubletrack nears the Torrente Ayasse, it enters a dense forest, and the route remains mostly forested until it reaches the town of Chardonney. After 2.5 miles, the trail opens into a clearing.
From this point, the trail base switches to loose stones, dropping about 400 m (1300 ft) in two miles. At points along this section, the stones in the roadbed are very loose and rutted.
