From Riells del Vai we will follow the carrer de Vallderrós to the bridge that crosses the torrent de Llòbrega; once crossed we will continue to the right along a track to the town's water tank. Follow the path that leaves the water tank, always uphill. The second turn-off on the left. A little further up, the ninth turn-off on the left to go to the Barbot Petit and the Cova de Vallderrós. To reach the latter, a few metres before the Barbot Petit you must descend, helped by a fixed plastic rope, and then climb a little up to the rock shelter.

To go to the Barbot Negre you must go back to the last turn-off made on the left and continue uphill in the direction of the dark-coloured travertines that lie above the path.
