The Adaja[a] is a river located in the centre of the Iberian Peninsula, in Spain. A major left-bank tributary of the Douro,[1] it flows 163 kilometres (101 mi), and its river basin drains an area of 5,328 square kilometres (2,057 mi2).[2]
It has its source in the so-called Fuente Berroqueña (Villatoro, province of Ávila), near the saddle point between La Serrota and the Sierra de Ávila.[2] Initially following a southwest-northeast course through the Amblés Valley, the Adaja then bends northward in Ávila, later receiving the contribution of its most important tributary, the Eresma, near Matapozuelos.[3] It empties into the Douro in the province of Valladolid near the town of Aniago.[4]
