View of the Monastery of Santa María la Real de Valdeiglesias

Highlight • Religious Site

The Cistercian monastery of Pelayos de la Presa is the oldest monastic complex in Madrid. It dates back to the 12th century, and although it was renovated in the 15th, its abandonment after the confiscation of Mendizabal has caused its current state.

Río Alberche

Highlight • River

There is a beach located in a place surrounded by vegetation where the Alberche river and the Perales river converge. In this place a sufficient amount of water is collected so that you can bathe calmly. You can also fish in some areas.

Picadas Reservoir

Highlight • Lake

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.

Labores Stream Pool

Highlight • Lake

A beautiful place, ideal for taking a break on your route and enjoying the wonderful landscape that surrounds this small pond that is located in the heart of the Alberche oak forest and on the bed of the Labores stream. If you are here in summer you can take the opportunity to take a refreshing swim.

Pelayos de la Presa Town Center

Highlight • Settlement

The name of the town of Pelayos de la Presa comes from San Pelayo, an old hermitage located between the current town and the San Esteban hill, while de la Presa takes its name from the stream that crosses its term.
