Going along the B-122 road from Terrassa to Rellinars, after km. 8 there is a bend and a bridge that crosses the torrent de la Serra Llarga. A few metres before, a track comes out on the right that first runs parallel to the road and then climbs up towards the ridge of the Serra Llarga. You pass under a first power line, and further on you reach a second power line. You continue and the track goes off to the right, crossing the torrent de la Serra Llarga and further on the torrent Maleït. A few metres beyond, an old track comes out on the right heading towards a high-voltage tower. At this point you must go down towards the torrent Maleït following alongside the high-voltage line (on its left side) and about 30 metres before reaching the torrent bed you find the entrance of the pit.
