From Mont-ral we will head W; once past the esplanade at the exit of the village, we find a crossroads. We will leave the path that climbs to La Foradada and the Pla de l'Avenc, and continue along the path heading NW. Once we have covered 75 metres, a path emerges from the left which we will follow; this path is marked from time to time with cairns. We will come to a first fork where we continue to the right; a little further on we find a small path on the left marked with cairns, we must follow them, as this path passes along the base of the cliff of the Serrat de l'Avenc, where the climbing walls and the gully containing the cavity are found. We will reach a point where we must climb a steep slope formed by an accumulation of blocks; when we descend on the other side the small path passes almost touching the wall. At this point we must begin the ascent up the wall, as the entrance is about 7 metres above the base and is not visible until you reach it.
