The CSIC grants specific predoctoral scholarships for El Ventorrillo.



Estación Alpina de Biología del GuadarramaIts beginning began in 1911, with the name of "Estación Alpina de Biología del Guadarrama ("Alpine Station of Biology of the Guadarrama)", and soon reached a great scientific prestige by the studies realized, as much by national and foreign investigators.


The first director of El Ventorrillo was Francisco de las Barras de Aragón, who started the activities of the Biological Station with the course "Natural History of the Sierra de Guadarrama.


Although currently Ventorrillo is not a place open to the public, but a work center, the National Museum of Natural Sciences, aware of the importance of disclosure, has given up some of its traveling exhibitions and has offered lectures in the villages of the Sierra , In particular in Cercedilla and Navacerrada, to inform its inhabitants, visitors and especially schoolchildren about their environment and the research work being carried out in their environment.


Also, in order to contribute to this informative work, there is a blog called " Observatorio de El Ventorrillo " ( which reports on research projects, books published on the Sierra de Guadarrama and a "field notebook" where you are invited to observe nature.
