Along the TP-3311 road from la Galera to la Sénia, towards km 14.5, on the right we find the mas d'en Berga, right at the junction of the lligallo de Sant Jaume that comes from Ulldecona; we will turn right and continue for 960 metres, where we will take a track on the right that we will follow for 1.64 metres; this ends in front of a field of malea. On the left we have an olive grove where the vehicle can be left, while on the right a path continues that after 85 metres places us in another olive grove; we will continue to the left through this field along the side of the malea until reaching the stone wall that bounds the olive grove, then we will continue to the right parallel to the wall until it ends; a few metres before it ends, one must cross the wall and from there we find a path between the malea that in 40 metres in direction W38N will take us to the cavity. At the entrance we find an old metal drum, which is used to prevent anyone from falling; it must be put back, but leaving a gap so that the bats can pass. The second entrance is covered with logs for the same reason. One must be careful at olive-picking time, since the farmers do not like their fallen olives being trodden on.
