We will take the C-59 road that goes from Castellterçol to Moià. Before reaching Moià, once we cross the bridge over the riera de Castellnou, we must take the first turnoff we find, a dirt track on the right. We will follow the track for about 500 m, until we reach the paret de la Falzia; here we will leave the car. We will continue a few metres, until we find a path that descends to the riera; once we cross the torrent we will find the rock shelter and, inside it, the font de la Falzia.
