Waterfall of o río das Gándaras Nature · Vilasantar, Betanzos, A Coruña A waterfall about fifteen metres high on the río das Gándaras, near where it flows into the Tambre; the stream runs through the concello past twenty-two water mills and a batán before plunging over the falls. It rises and ends entirely within Vilasantar, near Ril, in the parish of Barbeito, and its name refers to a low-lying, sandy, damp terrain where only scrub grows. Its course still drives the mechanism of one of the few surviving batáns on the Peninsula, today turned into a small museum in the hamlet of O Batán, which it gives its name to, and a hiking trail known as the Ruta dos Muíños follows its course.
