The cave is in Sant Llorenç del Munt. From km. 14 of the road from Castellar del Vallès to Sant Llorenç Savall, at the Revolt Rodó, you must go up the riera Seca to the confluence with the riera del Dalmau, then follow the bed of the latter, on our left. We will pass a track that leads to l'Adernar and continue upstream until we find a new fork on the left that leads to the Castellassa del Dalmau. The ascent begins on this path. We will leave the forks that lead to the Bassa del Dalmau and the Baga del Dalmau on the left and right, respectively. We will cross a torrent and must pay attention to our left, where a new path begins that will take us from the 600 mark to the foot of the cingle de la Castellassa. If we pass it, we will end up at the network of paths that lead to the font de Neda.

The path crosses a charcoal kiln when we are almost at the top. We will come out onto a rocky area with a drop on our left. Yellow marks are the sign of this path, which links up with the path of the carena del Peiret. The sign to turn off to our right is two holm oaks that cover the fall to the drop, just 20 metres along the rocky area. We will cross a boxwood grove until we reach the walls of the cingle de la Castellassa. To the right we would find the pinassa del Palleret (an imposing pine with a perimeter of 2.5 metres). We will continue as best we can to the left, close to the cliff. We will cross a gully and then find a well-worn chute at the top of which is the cave. Very approximate coordinates.
