From Embrun or Savines-le-Lac, reach Boscodon Abbey via the D568, taking the N94. When you reach the abbey, continue along the road on your left. The road turns into a forest track that is passable by car. Park your vehicle near the bridge over the Infernet.
You can also get there from the village of Les Crots near Embrun via the D90, but from the hamlet of Les Gendres, the road becomes a track that is not recommended for passenger vehicles.
(S/E) With your back to the bridge and facing west, turn left and follow the sign for "Grande cabane 1613m".
(1) At the sign, turn right towards Col de la Rousse, passing in front of the large hut and going around it on the right.
(2) At the sign, continue to the right towards Col de la Rousse, leaving the forest path and taking a trail for a steep climb through the woods.
(3) At the sign, take the path on the left towards Le Clos Besson. This path, known as the chemin de ceinture, is very pleasant after the slightly steep climb.
(4) You are now at the Cabane des Olettes. You may be greeted by one or two Pyrenean sheepdogs (Patou). If there is a flock of sheep present, do not try to approach them. Pass by at a distance (with a smile).
From the hut, continue climbing on the path, which is less visible at first, heading east. You will leave the Vallon des Olettes to join the one on the left. You will have to cross several small streams, which is not difficult.
(5) At the sign for "Le Clos des Dames 2127m", leave the circular path and turn left towards Pont de la Grande Cabane 2.7km.
(6) At the sign for "La Combe de la Perouyère 2053m", continue left towards Pont de la Grande Cabane 2.2km. From here, you are no longer on the path shown on the IGN map. It seems that the route has been changed to avoid passing near Cabane de la Perouyère. To find the forest path again, you will need to follow a trail that is not always easy to spot, which zigzags at the beginning and brings you closer to the Torrent des Olettes. Do not go down to the torrent. Continue to the right in a semicircle, staying at roughly the same altitude, to rejoin the forest path.
(7) Return to the forest path at a hairpin bend. Descend this path on the left to reach the crossroads you passed on the way up.
(1) Turn right towards the bridge that crosses the Torrent de l'Infernet and leads back to the car park (S/E).
