Attractions and Places To See around Cadalso De Los Vidrios - Top 20

Beautiful and easy path along the Alberche river.

La Presa de Picadas is a hydraulic infrastructure located on the Alberche River, which gives rise to the reservoir of the same name. Surrounded by a natural environment of great beauty, it stands out for its rugged landscapes, pine forests, and calm waters, making it an ideal point of interest to enjoy nature in the Sierra Oeste of Madrid.

A nice climb from the El Burguillo reservoir. The first part is asphalt in very good condition (as of November 1, 2025), and the second part is a dirt track, also in very good condition. It's a demanding climb; the asphalt section offers some flatter sections, but the dirt track is practically a continuous gradient of around 10%.

A must-see if you go to the El Tiemblo chestnut grove.

The section between San Martín de Valdeiglesias and Aldea del Fresno is very comforting due to the route of the old Alberche train. The path is favorable and you simply have to maintain your inertia through the pine forests of Pelayos de la Presa and the shore of the Picadas reservoir to the dam wall, a delightful cycling ride. At the dam you have to cross a small slope and go down to the Alberche River bridge in Aldea del Fresno, which due to recent floods was under repair the day we passed. The route continues along the entertaining and sandy Camino de Navayuncosa, passing by the Palace of the Count of Caralt and following a section of the old railway to Villamanta, where we once again find damage to the road due to flooding. In the municipality of Navalcarnero we follow the milestones of CiclaMadrid along the rural roads marked with carved and sculpted granite posts with the names of the paths and roads of the municipality, on the map it says Camino de Madrid and on the stone post Camino from Valdeyeso. Navalcarnero has a stop in the square, it is monumental and a good place to have the last snack before the final push. In the Dehesa de Marimartín we reconnect with the route of the old Alberche railway, we pass over the iron bridge of the Guadarrama River and along the greenway we immediately arrive at the lonely streets of Mostoles Tecnológico. In this section, the CiclaMadrid milestones follow a rather uncomfortable livestock route through industrial estates and urban areas, until they cross the peripheral urbanizations of Villaviciosa de Odón and through the old military camps of Venta de la Rubia and the Meaques stream, they enter the Cottage.

A true Ent

The disturbing descent from the Santa Ana urbanization ends at the Vía Verde del Alberche, built on the old route of a railway that was intended to connect Aldea del Fresno and Pelayos de la Presa, but was never inaugurated. In this section the Alberche River is dammed by the Picadas dam and it is delicious to pedal through the canyon to a recreational area before exiting onto the M-501 highway. The railway was planned in 1930 as a secondary branch of the main Madrid-Almorox line. The plan was to create a railway communication route between Aldea del Fresno and Arenas de San Pedro, passing through Pelayos de la Presa, San Martín de Valdeiglesias and the Tiétar valley. The works began very lively, bridges were built and remains of the track bed remain in several sections, but the arrival of the Civil War cut off the works and they were never resumed. Now, the sections built almost a century ago are a wonderful greenway in the Sierra Oeste.
