Access: to get to the start, go through the village of La Bâthie on the D990, near the N90 interchange, south of the village of Tours-en-Savoie. Take the D65 and climb up to the hamlet of Le Daru, passing through the hamlets of Le Fugier, Montesseaux, Lachat and Le Mondon. At Le Daru, continue towards La Ravoire and Bellachat. At the end of the paved road, take the long track on the left to reach the Bellachat car park after about 20 minutes.
(S/E) Follow the track to quickly reach a Y-junction.
(1) Take the path on the left to reach the Chalets de Bellachat. Continue, turning right, heading north, at the crossroads to reach the Croix de Dormiaz, visible from the Chalets.
(2) Continue to reach the summit ridge. Follow it through a series of ascents and descents to reach the Col des Lacs pass.
