From Mont-ral we head W; once past the esplanade at the exit of the village we come to a crossroads. We leave the path that climbs to La Foradada and the Pla de l'Avenc, and follow the path in a NW direction. Once we have covered 75 metres, a path comes out on the left which we follow, marked here and there with cairns and red dots. We come to a first fork where we keep right; a little further on we find a small path on the left marked with cairns and the red dots, which must be followed, as this path leads to the Teix mil·lenari. We 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 where we observe stalagmitic flows. A few metres further on, before the path begins to climb, we turn off to the right to a small col between the large blocks, where just below the col the lower mouth of the cavity opens; a small detour must be made at the mouth and we descend over the blocks until reaching the large funnel that forms the mouth. To reach the upper mouth, follow the wall where the cavity opens, climbing the slope up to the highest part.
