On the western slope of Montcau (Sant Llorenç del Munt). Very approximate coordinates.

To reach it, start the walk on the path that leads from coll d'Estenalles to the cimal dels Cortins; once the bed of the canal del Séc has been crossed, leave the path to the left, descending until you find a charcoal burner's hut and a nearby boulder field. From this boulder field we will set off at its start in a N direction without losing height. Once we enter the forest, we will begin to lose height, first passing a small channel at the head of which is the cova Penjada del Montcau. Then we will cross a boulder field, after which we will find the cova Oest del Montcau. If we continue without losing height, we will find a stretch of collapsed cliff face above which is the cova d'Estenalles.
