Nervión is a river that runs through the town of Bilbao, Spain into the Cantabrian Sea. Its lowermost course, downstream of its confluence with the Ibaizabal River, is known as the Estuary of Bilbao. The river is 72 kilometres long from its source at the Burgos and Alava provincial limits to the sea and runs in a South to North direction. Soon after its source, the river forms a spectacular 300-metre waterfall in the Delika canyon and then enters the Biscay province through the city of Orduña. This waterfall is the largest in Spain with its 222 metres. It re-enters Alava through the towns of Amurrio and Llodio. The river then runs back into Biscay province and out to the Cantabrian sea, entering the Bilbao metropolitan area at Ugao-Miraballes. The tidal influence reaches 15 kilometres inland from the sea, in Bilbao's old town.
