The most salient feature of the railway line trail from Sant Feliu de Guíxols to Girona is the smoothness of its slopes and curves. The route is formed by a winding line that was mathematically mapped out over the rugged terrain. The paving is of a grainy “granite sand” type material that blends in nicely with the terrain it crosses, although there are also urban sections at all the towns that it runs through. After leaving Girona behind, the route crosses the Selva depression, characterised by a patchwork mosaic formed by alternating croplands and forests. On clear days you can enjoy an extraordinary panoramic view that encompasses the easternmost mountains of the Pyrenees range all the way down to the Montseny massif, including the coastal Serralada Transversal (El Far, Sant Roc, Rocacorba). The second half of the section crosses the Ridaura valley, which separates the Cadiretes massif to the south from the Gavarres massif, and runs gently down to the seaside town of Sant Feliu de Guíxols, the birthplace of the Costa Brava place name, which offers breathtaking seascapes and views of the surrounding countryside. When we reach the area of Cassà de la Selva, we can join the Thermal Route, a greenway which takes us to Caldes de Malavella.
