From Allos, head towards Villard-Bas/Lac d'Allos and continue along the road to the Laus car park, the last car park on the road, which is subject to a charge depending on the time of year.
(S/E) With your back to the access road, head towards the back of the car park and take the path next to the large information board. There are various information boards along the way. Join the path coming from the forest house on your left and continue.
(1) Look for the path climbing up the embankment on the left and take it. Walk through the undergrowth and then cross a meadow to the next crossroads. Be careful, as marmots are often seen in this meadow.
(2) At the crossroads, turn left. Then cross the footbridge over the Méouille torrent and continue the ascent. At the intersection with a path climbing to the right (Col de la Petite Cayolle path), continue straight ahead. The path winds upwards at times and becomes very stony as you climb. "Be careful in the scree slopes where chamois may gather." Follow the main path to a sharp bend heading west.
(3) The path on the right leads to Lac du Trou de l'Aigle, but it is easier to spot on the way down.
Continue the ascent on the left into the Combe du Pelat via very long switchbacks. Continue in this manner to the summit of Mont Pelat, where you may need to use your hands for the last few metres.
(4) From the summit, enjoy the panoramic view of the Alps and, in good weather, Corsica. Descend via the same route to the fork towards Lac du Trou de l'Aigle.
(3) In this direction, the round-trip trail to this beautiful enclosed lake is more visible. Follow it (without markings) straight ahead to the lake.
(5) Turn around to find the main trail.
(3) Descend to the left until you reach the intersection just after the Méouille torrent.
(2) Turn left towards Lac d'Allos and reach it at the Notre-Dame des Monts chapel.
(6) Turn right between the chapel and the refuge, then right again a few hundred metres further on to reach the intersection at the start of the route.
(1) Descend on the left to return to the Laus car park (S/E).
