To reach the start, go via the village of La Bâthie on the D990, near the N90 junction, south of the village of Tours-en-Savoie. Take the D65 and head up to the hamlet of Le Daru, passing through the hamlets of Fugier, Montesseaux, Lachat and Le Mondon. At Le Daru, continue towards La Ravoire and Bellachat. At the end of the tarmac road, carry on straight ahead along the track towards La Ravoire and park at the bridge crossing the stream.
(S/E) Take the path leading uphill on the right. After about thirty minutes, you’ll reach a plateau and a crossroads.
(1) Ignore the path on your right. Continue along the faintly marked path across the plateau. You’ll reach a second plateau; once there, keep to the right. After a short climb, you’ll join a track.
(2) Continue left along the track, passing the Chalets de Bellachat (where Beaufort d’alpage is produced). Take the path into the mountain pasture and, after about a hundred metres, turn right onto the path heading due north to reach another junction.
(3) At the crossroads, turn right onto the path heading due north. Head towards the Croix de Dormiaz, visible from the chalets.
(4) Continue on to reach the summit ridge. Follow it through a series of ascents and descents to reach the Col des Lacs pass.
(5) Ignore the paths to the right and left here; continue along the ridge, heading north-east, to reach the Pointe de la Grande Journée after a final steep climb.
(6) Take the ridge to the right, heading due east, and descend. Then veer right to reach Lac Sans Fond.
(7) Follow the bed of the stream, which is dry in summer, and head for the junction with the GRP® du Tour du Beaufortain near the Lacs de Lavouet.
(8) Head up to the right along the GRP® for a few metres, then turn left at the cairn onto the faintly marked path. The path is fairly flat. Follow the cairns and pass close to the Cascade de Lavouet. Descend a fairly steep slope, which levels off towards the end, to reach the track at the Col de la Bathie
(9) Cross the track and head left, following the path below it; the path is not very well marked for the first fifty metres. Follow the path until you reach the junction from the outward journey.
(1) Continue to the left, following the route in reverse to return to the car park (S/E).
