Our advice: switch off your Sat Nav when you get to Albertville to avoid suggestions of roads that are closed in the winter.
From Chambery, take motorway A43 and A430 to Albertville, then the N90 towards Bourg-Saint-Maurice as far as Bellentre. Shortly after Bellentre, follow signs to Montchavin-Les Coches on your right.
Get out at Landry station in the valley then taxi or bus up to Montchavin-Les Coches. You can get your bus ticket at Landry train station or book it in advance on https://billet.vente-bellesavoieexpress.fr or www.altibus.com. Don’t forget to book your return journey at least 48hr in advance from the Tourist Office.
