Riserva Naturale Regionale di Bergeggi

Not very far from it there is another interesting cave, that of the "Galleria Ferroviaria" (Railway Gallery), a karst cave developing for more than 400 meters. It was casually discovered in 1870, during the excavations for the railway gallery crossing the Bergeggi promontory. The opening gallery of the cave has been in disuse for years, but the initial stretch of the karst cavity still shows the dirt of the soot produced by the steam locomotives. The cave consists of several halls of different dimensions. The bottom of the largest hall housed a beautiful lake which no longer exists because the building of the new railway gallery uphill the cave changed the course of the water bearing layer feeding it.
