  • Towns and villages: Horcajuelo de la Sierra, Montejo de la Sierra, Prádena del Rincón, La Hiruela, Puebla de la Sierra.

Points of interest

Located less than a hundred kilometers from Madrid, the Sierra del Rincón Biosphere Reserve is a mountainous territory between the Ayllón and Somosierra massifs. It is known as one of the most beautiful and least discovered places in the Community of Madrid.

Historically, the low fertility of the land and the harsh climate were key to the emergence of a landscape dominated by forestry and livestock in a generally underpopulated area of Spain. Improvements in road and rail networks and the discovery/protection of the beech forest known as Hayedo de Montejo has generated a fair amount of rural tourism in the area.

Over the years, a coexistence between human activities and nature in this mountain environment has conserved a wide cultural and natural diversity difficult to contemplate so close to the capital city of Spain and here we find a spectacular landscape in which Mediterranean and Atlantic habitats range from 900 metre to 2000 metre peaks.

The Sierra del Rincón Mountains are home to exceptional flora and fauna. Besides having a broad range of different habitats (forests of pine, oak, holm oak and beech, pastureland, rocky landscapes, etc.), this is also home to unique flora, with 833 species, 66 of which are rare, endemic or endangered. There is also a large variety of fauna: of the 194 species of vertebrates to be found, 140 are rare, endemic or endangered. Autochthonous breeds of livestock and traditional crops cultivated to this day also help to conserve the local environment.

Walking in the Sierra del Rincón Biosphere Reserve

There is a network of trails made up of around 20 routes marked with the name “Green Paths of Madrid” (Sendas Verdes de Madrid), in addition the area is crossed by the GR88 and the GR303 footpaths that are entirely within the limits of the reserve and pass through the 5 villages.

Information Centres

Each village in the area has information points, something of ethnographic interest and they are well worth visiting but the main information point to visit is the Centro de información de la reserva de la biosphera Sierra del Rincón where they also coordinate the entrance permits for the Hayedo beech forest.

A visit to the beech forest is free and is guided. Dogs are not allowed (unless they are registered for the blind or partially sighted).

There is a permanent exhibition covering an introduction to the Sierra del Rincón (its nature, landscapes, culture, customs and gastronomy). There are two large rooms with information, exhibition panels, videos and also a scale model of the area

Reserva del Regajal-Mar de Ontígola

With an area of ​​almost 630 hectares, the El Regajal-Mar de Ontígola Nature Reserve (Reserva del Regajal-Mar de Ontígola) habitat brings together a characteristic fauna of the Mediterranean-sub-desert mountains, with species such as hare, rabbit, wild boar, tawny owl, partridge and blackbird being very common. The gypsum hills with endemic flora species and unique vegetation and are populated with species such as kermes oak and rosemary are well preserved.

The Natural Reserve of El Regajal-Mar de Ontígola is one of the most unknown natural spaces in the Community of Madrid, despite having a great wealth of fauna . This is due to the fact that most of its 630 hectares are on private farms. (The one of El Regajal stands out, which has its own vineyards and winery attached to the designation of origin of Vinos de Madrid.)

However, the main wildlife interest here lies in its butterfly populations for which it has been internationally recognized as one of the most important butterfly reserves in Spain. Over 100 of the 230 odd species of lepidoptera of Spain have been recorded here which is interesting not only for their number but also for the rarity of some of them. In 1979 entomologists from the International Union for Conservation of Nature (IUCN) ranked El Regajal as the fifth world priority in conservation due to the importance of its butterflies.

The site is included within the Special Conservation Zone (ZEC) of Las Vegas, slopes and moors of the southeast of Madrid, which, in turn, is listed as a Site of Community Interest (SCI) and attached to the Natura 2000 Network of the European Union. Due to the importance of its avifauna, it is also part of the Special Protection Area for Birds (ZEPA) of the Carrizales and Sotos de Aranjuez.

An interesting history.

The origins of the Sea of ​​Ontígola go back to 1552, when Felipe II (1527-1598), while still a prince, signed an instruction in which he urged Diego López de Medrano, governor of the administration of the territory of Aranjuez to build “a very large lagoon in the Ontígola stream, and another two or three small ones in the one towards Ciruelos in order to atract birdlife“. (Presumably ducks for eating?)

The works began at the end of 1560 under the direction of Juan Bautista de Toledo (1515-1567) and the master builders Juan de Castro and Francisco Sánchez participated as well as the Dutch dyke experts Adrian van der Müller and Pierre Jasen. The project was completed in 1572.

Although the reservoir was conceived for the irrigation of different orchards and gardens, it also developed a rather gruesome recreational reputation whereby in the 17th and 18th centuries sailing was practiced and tournaments, parties and games were held. One particular “game” consisted of hunting animals, preferably fighting bulls, which were thrown into the lagoon from the cliffs and once in the water killed in the most dramatic way possible..

In 1625, Felipe IV (1605-1665) commissioned the architect Juan Gómez de Mora (1586-1648) to build an artificial island, on which a gazebo, a jetty and a firing point were set up. Seventy years later, in 1695, a small bullring was also built in the vicinity of Mar de Ontígola

In the 18th century, various hydraulic infrastructures were built, aimed at optimizing the flow of the reservoir. In 1734 the so-called Mar Chico was created, a settling pond linked to the Mar de Ontígola, from which a water conduit came to the island’s garden and during the reign of Carlos IV (1748-1819) a new canal was made that reached the garden of the Prince.

The Regajal-Mar de Ontígola is on the Red List of Heritage in Danger due to its poor state of conservation. Regarding the dam, both the retaining wall and the spillways are covered with earth and weeds, which causes the water to overflow from the crown, with the consequent degradation of the structure. Likewise, the accumulation of sludge and the proliferation of invasive plants, mainly reeds , has caused a notable decrease in the storage capacity of the reservoir.

Of course the dilemma is clean and repair or just let nature have its way. Time will tell.

Current threats and future

This enclave so privileged from the point of view of biodiversity, whose conservation depends on the Community of Madrid, is, however, threatened. So much so that in the last 25 years up to seven species of diurnal butterflies have disappeared , according to studies by the three researchers José González Granados, Carlos Gómez de Aizopurúa and José Luis Viejo Montesinos, who have been studying the wildlife here for many years.

In 2001 these naturalists embarked on a project, together with the Community of Madrid, which consisted in the creation of a butterfly farm for the breeding and study of autochthonous species but In 2011 the project failed and what was once the largest butterfly farm in Spain has been closed. In 2013, the Aranjuez City Council requested a grant from the European Life program to be able reopen but as of 2021 still no sign of it reopening…….

The Fauna Refuge of San Juan Lagoon

The Fauna Refuge of San Juan Lagoon (Refugio de fauna de la Laguna de San Juan) covers an area of 40 hectares and is found along the lower course of the River Tajuña. It is an important wetland area close to the town of Chinchón and one of the largest bird reserves in the Community of Madrid.

It became a protected area in1991 and is devoted to preserving, restoring and improving the fauna and flora for biological, scientific and educational purposes.

Surrounded by reeds, rushes and cane as well as other species It is perhaps the best example of the marshy ecosystem in the province of Madrid and an ideal habitat for water fowl. Over 43 species of vertebrates have been catalogued, of which around half are birds. Some make their home here all through the year whilst others are wintering or make sporadic visits during migration periods.

There is a small hide and a few information panels explaining some of the wildlife present in the area (Mostly birdlife)

South East Regional Park

  • Region: Madrid
  • Declared a Regional Park: 1994
  • Park surface area: 31,552 hectares
  • Towns and villages: Velilla de San Antonio, Ciempozuelos, Titulcia, Rivas-Vaciamadrid, San Martín de la Vega, Morata de Tajuña, Arganda del Rey, San Fernando de Henares, Pinto, Mejorada del Campo, Getafe, Valdemoro, Aranjuez, Chinchón, Torrejón de Ardoz, Coslada and Madrid

Points of interest

The South East Regional Park (Parque regional del Sureste) is an area of Madrid that extends from north to south along the Jarama river and presents a great variety of habitats some of which are considered the best and well preserved wetlands in the Comunity of Madrid such as the Mar de Ontígola close to the town of Aranjuez, Laguna de San Juan near Chinchón and the gravel pits between the rivers Jarama, Manzanares and Henares (Soto de las Juntas and El Campillo).

The natural wealth of this area also resides in the fertile cereal plains, the gypsum cliffs of the hills and the emblematic area of Cerros de la Marañosa.

Some parts have undergone quite extensive restoration since the quarries and gravel pits closed with the planting of poplars (Populus alba) and willows (Salix alba) with these areas now protected as a wildlife reserves.

The shrubby and low habitat produces a landscape with large open spaces favoring steppe birds such as bustards, little bustards and curlews and where the slopes become vertical walls forming beautiful cliffs, peregrine falcons, eagle owls, red-billed choughs and black kites are present. Booted and short-toed eagles, goshawks and small owls frequent the forests formed by pine and kermes oak, accompanied by holm oak and gall oak, along with mammalls such as stone marten, rabbit, genet and fox.

This fascinating biological diversity coexists closely with the large and (very) nearby urban population centers and it is important o remember that around 50% of the territory of the Regional Park is occupied by arable crops and farmland.
