Living and selling in the Sierra Oeste

The area that regional statistics call Sierra Sur is popularly known as the Sierra Oeste: the mountainous south-west of the Madrid region, on the border with Ávila and Toledo, between the foothills of the Guadarrama and Gredos ranges. It brings together 14 municipalities and around 41,000 inhabitants. San Martín de Valdeiglesias, with the Coracera castle, is its main town; other well-known villages are Cadalso de los Vidrios, Cenicientos, Pelayos de la Presa, Navas del Rey and Robledo de Chavela. The San Juan reservoir, with a bathing area, draws many visitors in summer.

Village houses and detached houses on estates predominate, many of them second homes, among pine forests, holm oaks and the vineyards of the Vinos de Madrid wine region. Connections are mainly by road, with the M-501 (the 'reservoirs road'), and by bus; in the north of the area, Zarzalejo, Robledo de Chavela and Santa María de la Alameda have railway stations. Prices are among the lowest in the region.
