Cuenca Alta del Río Manzanares

Cuenca Alta del Río Manzanares is a vast protected area northwest of Madrid, spanning the upper course of the Manzanares River at the foot of the southern slopes of the Sierra de Guadarrama. Established as a regional park in 1985, it covers more than 42,000 hectares, making it the largest protected area in the Community of Madrid. Its main reference towns are Manzanares el Real and Hoyo de Manzanares, though the park's boundaries stretch much further, also taking in Monte de El Pardo and the adjoining Soto de Viñuelas.

Why does this place hold biosphere reserve status?

In 1992, UNESCO designated Cuenca Alta del Manzanares a Biosphere Reserve, adding it to the international network of areas that manage to balance local community development with environmental protection. The designation recognized the presence of threatened species, the park's proximity to a major urban center (Madrid lies only a short distance away), and the survival of traditional agricultural systems alongside distinctive Mediterranean landscapes. It is a rare case of a large metropolis pressing right up against a well-preserved natural environment.

What landscapes and ecosystems does the park hold?

Elevations within the park range from roughly 600 to 2,300 meters, producing considerable landscape variety, from gentle plains to rocky peaks and lower mountain ranges. Within its boundaries visitors find pine forests, holm oak woodlands, juniper stands, rockrose scrubland, and patches of Spanish (Portuguese) oak, along with wetlands scattered through river valleys and around reservoirs. This mosaic of habitats makes the park a refuge for numerous plant and animal species typical of the Mediterranean climate zone, including birds of prey that nest on the area's rocky cliffs.

What is there to see nearby?

The park serves as a natural recreational area for the population of Madrid, criss-crossed by hiking and cycling trails that let visitors take in both the granite rock formations of La Pedriza and the surroundings of the Santillana reservoir. Near Manzanares el Real stands a medieval castle, which together with views of the Guadarrama mountains forms one of the region's most recognizable scenes. Monte de El Pardo, part of the park, historically served as hunting grounds and today remains one of the best-preserved stretches of Mediterranean forest close to a major European city.
