The Narrow-Gauge Railway Route stretches out 39.7 km. With a smooth incline from Girona to Sant Feliu de Guíxols (15 m), its highest point is at Cassà de la Selva (136 m). Following the old narrow-gauge railway line from Girona to Sant Feliu, you can get to know two of Girona´s regions - the Gironès and the Baix Empordà - from the Ter River basin, crossing the Selva depression and ending in the Ridaura valley.
