Take the path under the bridge with a sign indicating "Etang de Pédourès - Refuge du Rulhe", very steep, which passes at the foot of an electricity pylon and climbs in switchbacks. It passes under the penstock then turns to the southwest, rising on the right bank of the Siscar stream, which it crosses by a stone bridge until it reaches a junction.
