Cañadas Reales (Drovers' road) Soriana Oriental
Born near Abejar in Soria, in the Sierra de las Cabrejas, where it coincides with the Galiana gorge. With the Glen Segoviana it coincides in the port of Somosierra and with the Eastern Leonesa in the port of Guadarrama. In addition, this glen meets the Leonesa Oriental, in Sancho Reja (Ávila), and the one in La Plata, in Los Santos (Salamanca). It arrives almost to Portugal, specifically near Olivenza in Badajoz.
