This itinerary passes near a spectacular basaltic cliff, not only for its height, but also for the houses built right on its edge.
The trail starts at the Plaça Nova in Castellfollit de la Roca, in the old part of the village, where there is a free public car park. Continue along Carrer Major until you reach the Town Hall clock tower. Follow the street downhill until you come to some stairs which will take you down to the bridge, which you cross. Once you are in front of the Mont-Roc restaurant, follow a path down toward the vegetable gardens and then a tarmacked street to the footbridge over the Fluvià River. From here, you can see the basalt cliff face. After crossing the footbridge, continue walking beside the vegetable gardens until you reach a small rebuilt Romanesque bridge. Cross the bridge and walk up along the Roman road, which will take you to the old village church. It is worth going to the viewpoint to enjoy the view. Follow Carrer Major toward the Town Hall until you are back in Plaça Nova.
