Covarey (Champdepraz) – Château (Champorcher)

From the Verrès freeway exit, turn left in the direction of Aosta.After a couple of kilometers, on the left, you will find the junction for Champdepraz with signs for the Mont Avic Nature Park.You go through the entire village and begin to climb the Chalamy valley, with its many hairpin bends.You continue until you reach the Covarey parking lot, where you leave your car.

From Covarey continue along the asphalt road with limited traffic, pass the Visitor Center, where a large model of the Mont Avic Natural Park territory is visible, and continue until you reach the small Veulla parking lot where the road ends.
From here, take the stone-bottomed road (used in the past for transporting ferrous material) that passes above the beautiful chapel and gently crosses the wooded side of the valley. Cross a few small streams and then skirt the Chalamy stream to reach the Servaz huts (if you head to the left, you will reach the remains of the blast furnace in a few minutes).
You climb up the back of the huts along the trail that with steep turns continues into the forest; you cross the junction of the trail coming from Praz-Oursie. After a flatter area, and passing a monumental pine tree, you reach Lake Servaz (often invaded by a showy bloom of water buttercups).
You skirt the lake and climb up into the forest to a knoll.
From this point, you descend slightly until you cross the stream coming from Lake Bianco. The trail crosses on level ground, passes near a renovated hut and climbs back up among mounded rocks on which there are several erratic boulders, i.e., boulders left by the glacier as it melted, to reach a lookout with signs created by the park. From here, it is a short walk to the Barbustel hut. From the hut it is less than half an hour up to the Col du Lac Blanc where you overlook the Champorcher valley.
You descend a steep section, then continue on a gentler path following the wide basin with sparse larches and reach Lake Muffé where you will find the namesake refreshment point. A few dozen meters to the right you can visit the "garden of sky and time." Continue downhill and at a hairpin bend in the trail continue left on a level path until you reach Alpe Cort. From here you descend directly to Grand Mont Blanc and then to Château.
