It comprises the villages of Derroñadas, El Royo, Hinojosa de la Sierra, Langosto and Vilviestre de los Nabos, while El Valle, watered by the river Razón, is popularly known as the Little Switzerland of Soria for its greenery and is the birthplace of Soria butter, which holds a protected designation of origin. El Royo, the district's chief town, stands at 1,070 metres above sea level and overlooks 127 square kilometres of territory. Photo: Gartxoak (CC BY-SA 4.0) What to see and do in El Royo
