About 50 metres above the right slope of the Sant Marc ravine.

There are different options for the approach: from the road from la Juncosa del Montmell to Aiguaviva, past the coll de l'Arca and almost in front of the Claravalls farmhouses, a track in very good condition leaves and runs through the Sant Marc valley; the turn-off to Mas Bartomeu is left on the right and you continue straight on until a double bend (right-left) shortly before reaching the barranc de les Fontanilles. Beside the track there are steps cut into its edge and from here a small path-trail climbs steeply; following it and taking a fork to the right you reach the first entrance of the cave.

Access can also be made from the TP-2442 road from Sant Jaume dels Domenys to Pla de Manlleu, where past km. 8, almost in front of the Cal Sumoi farmhouse, a track leaves to the left that connects in the area of the barranc de les Fontanilles with another track coming from Aiguaviva and with the one described in the first itinerary.
