The cavity belongs to the municipality of Sant Feliu de Pallerols, in the comarca of Garrotxa. At the time it was mistakenly placed in the municipality of Rupit i Pruit, in the comarca of Osona; we assume this error came from the fact that access is from the Rupit road and that the house of Can Roca Roja is also located in that municipality, but the cavity is not.

Access: Going along the C-153 road from Rupit to the coll de Condreu, shortly after passing kilometre 35 and at the end of the straight where a large “estelada” is painted, we will turn left to take a track that first climbs parallel to the riera de Papalló, and then continues climbing parallel to the torrent de Coma-Serra in a second section; we will always follow the main track until we come out onto a flat area with cultivated fields, we will follow it until we reach a crossroads crossed by a power line, we will continue straight on and in less than 300 metres we will reach a cultivated field in the very middle of which we find the mas of Can Roca Roja. Instead of going towards the house, we will skirt the field on the left, where at the height of the house we will find an old forest track, we will follow it for about 15 metres where we will find a crossroads, we will follow the right-hand one to the end of the track, which ends a few metres before reaching a small flat area where there are some hunting reserve signs. If we look at the trees at this point, we will see that some are marked with red paint; we will follow these marks on the trees along a path through the middle of the forest and shortly we will find some small cairns beside the path that place us at the lower entrance of the avenc de Can Roca Roja nº2. From here we will follow the path we came along, which turns left and descends; the paint marks instead of red are blue tending to lilac, and we will soon find the cavity almost in the middle of the path.
