This trail is for the exclusive use of pedestrians and cyclists. It follows the old railway line from Olot to Girona (54 km). The trail meanders through a range of picturesque landscapes and places of cultural interest. The trail starts in Olot at Sant Roc Spring (see how to get there). The trail slopes in a gentle downwards direction from Olot (440 m) to Girona (70 m) and its highest point is at Coll d’en Bas, 558 meters above sea level. The Carrilet Greenway, with a height difference of 1.5%, is a low difficulty trail. The Coll d’en Bas is the highest point of the trail, but if you decide to explore it gradually and over several days, you can stop off and enjoy the different towns en-route.
