(S/E) Follow the signs for Lac d'Allos, pass the Maison Forestière du Laus and continue to a fork in the road.
(1) Turn left onto theGR®56Band follow the signs for "Col de la Petite Cayolle". Continue straight ahead at the first intersection, leaving the path on your right, which will be the return route.
(2) Continue to a crossroads.
(3) Leave the path on the right and go straight ahead on the trail that heads north and joins a new intersection.
(4) Turn right. The trail passes Lac de la Petite Cayolle.
(5) You will quickly reach the pass of the same name.
(6) At the pass, turn right to go around the lake on the heights. Follow the signs for "Lac des Garrets, Pas du Lausson".
(7) After skirting Lac des Garrets on the left, the trail climbs back up to the ridge, passes just below the Sommet de Lausson and ends at the Pas du Lausson (altitude 2,602 metres).
(8) Turn right and follow the signs for Lac d'Allos. You will rejoin theGR® trail you took on the way up.
(3) Turn left and continue to the next junction (elevation 2,259 metres). You now have two options.
(2) Either continue straight ahead on the path uphill to return to the car park or, if you still have energy, follow the sign for "Refuge du Lac d'Allos" on the left to reach the refuge.
(9) The spot is worth a break to enjoy the view of the lake, and why not grab a snack at the lake refuge? You can spend the night there (by booking in advance, of course) and set off on a new hike the next day.
After the refuge, leave the trail that heads south-east and goes around the lake to take the interpretive trail that will take you back to the first fork.
(1) Turn left to return to the car park where you started (S/E).
If you are only spending one day in Allos, this is THE hike to do! Impossible to get lost, beautiful scenery...
