By the C-37 road, from Sarral to Rocafort de Queralt, on reaching kilometre 10.775 you must turn right onto the TV-2333 road. After travelling 175 metres and once you have crossed the river of Vallverd, we will turn right onto a track not advisable for cars, where at 40 metres we will find a turn-off to the right that we will ignore, continuing to the left along the main track; at 480 metres from the start of the track we will find a new turn-off to the right that we will also ignore; we will continue straight on and at 900 metres we find a new turn-off to the right that we will likewise not take into account; at 1,040 metres we find a turn-off to the left that we will also ignore and continue straight on; at 1,120 metres we reach a junction, the left-hand path has a cable barring the way, you must follow the middle path; on reaching 1,500 metres from the road, we find a new junction where we will follow the left-hand path. A little further on we will find a widening where we will leave the vehicle. From here you must follow the track for 158 metres, where it ends and two torrents meet; we will follow the right-hand one, which over a distance of 330 metres will lead us to the cavity.
