By the C-63 road, before reaching Sant Feliu de Pallerols, specifically at kilometre 56700 metres, we will turn left where the start of the track leading to the mas de la Torre is. From the bridge (Pont Nou) one must go down to the riverbed and go up the river about 50 metres along the right hydrographic slope, where the cavity is found, shortly before reaching the old bridge, currently in ruins.
