District:
Park at the Basse Rua car park (S), opposite the refuge of the same name. Reach this car park via the Vars road. Be careful of traffic in summer as the road is very narrow and busy.
Start the hike on the wide track that follows on from the car park.
(1) Take the right-hand track at the first crossroads (signposted Col de Serenne). The track turns into a path, marked in yellow (PR®).
(2) Cross the stream and begin a steep climb through the woods to reach a crossroads.
(3) Leave the Col de la Coulette trail on your right and take the one on the left (signposted Vallon Laugier).
Walk leisurely through this valley.
(4) Cross the stream at the sheepfold on your left. Continue through this valley to reach the Col de Serenne after a very gentle walk.
(5) This pass is a major crossroads of trails:
- to the right, the trail coming from Vars and more specifically from the Bergerie des Couniers,
- the second on the right leads to the ridge and Lac de l'Étoile, then to Paneyron,
- the one opposite leads to Saint Paul sur Ubaye,
- and 90° to the left is the trail to Lac des Neuf Couleurs and Mortice.
Take this last trail and, after a few hairpin bends, you will easily reach the lake.
(6) Return via the same route to reach the car park where you started (S/E).
