Getting there
From Martigny, the St-Bernard Express climbs to Orsières in half an hour. Postal buses leave the station for Champex-Lac, for La Fouly in the Val Ferret, and in summer all the way to the Great St Bernard Pass. By car, leave the A9 at Martigny and follow the Orsières road; there are car parks beside Lac de Champex.
Good to know: buses up to Champex thin out outside the school holidays. Check the last return before setting off on a walk, as the valley empties quickly in late afternoon.
