(S/E) From the La Toussuire Tourist Office, walk up through the village to the top of the high street, via Rue Verte, then Rue Blanche (D78).
Caution: traffic.
(1) Take the path leading uphill to the left (Rue du Marolay) to pass in front of the Youth Hostel and to the right of the snowmaking plant. Follow the farm track uphill, following the yellow signs for “la Tête de Bellard”. Ignore the paths on the right leading towards the water reservoirs.
(2) Continue to the left, ignoring the path on the right that leads directly to the Col du Marolay. Carry on to the Tête de Bellard and its viewpoint. Up there, there is a restaurant (closed during our hike) and the top station of the Tête de Bellard chairlift.
(3) Walk past the chairlift terminus and follow the ridge north-east towards the Col du Marolay and the Grand Truc. Follow the yellow signs. The ridge path is not always very well signposted or visible, particularly from the start at the Tête de Bellard.
(4) Once at the Col du Marolay, continue straight on towards the Grand Truc, staying on the ridge path. At the 2106m point, turn right towards the mast.
(5) At the Grand Truc, continue along the ridge for about 500m until you reach a fork (2142m). Turn right and head down towards La Toussuire. You will need to cross a field where sheepdogs are guarding the sheep (see practical information ¹). In our case, there were four of them. Above all, do not startle them; stay calm and pass slowly. They need to understand that you are not a predator. We weren’t entirely reassured, but we managed to cross anyway. Descend to La Toussuire via Le Plan du Lachat and La Lauzaz.
(6) Once you reach the village road (Rue des Chasseurs Alpins), turn left for about 200m then turn right to take the Chemin de la Boucle du fil de l'eau (marked on a yellow sign). Follow this path alongside the stream, cross the footbridge and continue to the Tourist Office (S/E).
