From Cervinia, you drive south passing Valtournenche and following the main road till Buisson where is the cableway going up to Chamois. Leave your car in the parking lot below the station and get a return ticket (3 €). Courses are every 30 minutes (at 8, 8.30, 9 etc.). The cableway lifts you 600 m. over Buisson to a sunny slope with a small village of about 100 people. You may get excellent sandwiches in the café just over the main square or getting some food for a picnic in the well stocked bazar. From the square a chairlift takes you to Lod Lake where you find a small restaurant (Gabriella). You have also two other chairlifts reaching the ridge over Cheneil: it’s a very easy way to reach the Clavalité sanctuary avoiding the walk (from Chamois, along the skiruns, or from Cheneil in the woods).Google Maps directions.
