This protected area was declared an Integral Nature Reserve of Inagua in 1987. This reserve is included within the area of the Nublo Rural Park and covers the municipalities of Tejeda, Mogán and San Nicolás de Tolentino. The mountains, Inagua, Ojeda and Pajonales are home to one of the best-preserved natural pine forests in Gran Canaria. This feature, together with the fact that it is home to several major ravine sources, such as the Mulato and the Mogán, means that it plays a key role in groundwater recharge and soil conservation. Furthermore, this area is of great scientific, geological and geomorphological interest and has a spectacular landscape.
