From el Perelló along the TV-3022 road towards Rasquera, at kilometre 3.86 there is a large lay-by on the left-hand side where you can leave the road and take the dirt track that continues in the opposite direction to the one we were coming from. At 240 metres we come to a junction; we continue along the middle path for 80 metres, where we find a new junction that we follow to the left and, 75 metres further on, we turn off to the right. We follow this track for 1 kilometre, until we reach a junction where we park; if a 4×4 vehicle is available, you can continue about 225 metres along the left-hand path, which is in poor condition. At this point we find a sharp left-hand bend that heads towards the reservoir. From the sharp bend, the cavity is about 100 metres away, climbing up the slope and with a height difference of about 40 metres. Approximate coordinates.
