Join the third hairpin bend by the road towards Vicdessos (to the east).
2 - Start of the trail
Take the path on your left which begins with a slight difference in height and join the small Pont de Ganioule.
3 - Ganioule bridge
Just after the bridge, turn off to the left. The height difference becomes more difficult until the Etang d'Arbu.
4 - Orri of the Three Lords
It is possible to take a break in the shelter of the Three Lords (Orri). The Étang d'Arbu is the ideal spot to eat and rest with a sublime view. Resume the ascent, steep at times, with the possibility of encountering blocks of frozen snow in winter. Go through a few very steep passages (easy climbing passages - level 1) and arrive at a fork near the ridge.
5 - Branch
Turn right to continue the ascent (steep with occasional patches of frozen snow during winter) until you reach the Pic des Trois Seigneurs.
6 - Peak of the 3 lords
Take advantage of the incredible view from the Peak and turn back to return to the previous fork.
7 - Branch, right
Leave the path of the ascent on your left and walk along the ridge which offers you a spectacular view. Reach the Pic de Barrès.
8 - Pic de Barrès
Continue on the ridge to a small pass (2005 rating), an ideal place to rest or enjoy the scenery. Continue to the Pic de Fontanette.
