Upper Champorcher Valley

This route allows you to explore a large part of Mont Avic Park. It also passes through the territories of Champdepraz and Fénis.
The trail crosses four passes: Col del Lago Bianco, Col Mézouve, Col Eyele, and Col Fussy.
Along the way, you can admire many stunning lakes, including the Gran Lago, the second largest natural lake in the Aosta Valley.
If considered as a training itinerary, the times are calculated assuming a speed of one and a half times normal pace (approximately 450 meters in altitude gain per hour).

From the Pont-Saint-Martin motorway exit, turn left toward Aosta. At the roundabout, continue left, still following signs for Aosta.
Pass through Donnas and reach Bard. After the village, at the roundabout, turn left toward Champorcher. Cross the village of Hône and enter the Val di Champorcher. Pass Pontboset and continue to Champorcher. Continue past the village to reach Chardonney, where the large ski lift car park is located.
From the Verrès motorway exit, turn right toward Turin, pass Arnad, and at the roundabout, turn right toward Champorcher.

From the car park, go up the steep mule track leading to Petit Mont Blanc (the trailhead is not very visible) and continue to La Cort, where just above you will find the well-frequented trail leading to Barbustel Refuge.
Reach the refreshment point and Lake Muffè, and follow a gentler route—with the exception of a slightly steeper final stretch—to Col del Lake Bianco. From the pass, descend a stony valley. At one point, the entire Monte Rosa range appears against the sky. Soon after, you reach Barbustel Refuge.
From the refuge, descend to the small bridge between Lake Bianco and Lake Nero, then ascend along the traverse (with Lake Cornuto visible below) until you reach the Gran Lago, which you follow along the right side. Passing several other lakes, you arrive at Col Mézouve.
From the pass, descend the wide valley, skirting the right side of Lago Margheron almost to the Forestry cabin, then turn left to cross the plain and take the steep trail leading to Col Estsèly (or Eyeles).
From the pass, follow the hunting mule track to Col Fussy. From there, descend along the official mule track to the valley floor, where the main road of Miserin leads to Dondena Refuge.
After a break at the refuge, descend steeply to cross the bridge over the stream, then shortly after turn right onto Alta Via No. 1, which you follow to Chardonney, where the car is parked.
