The Peñalara Massif is the site with the highest concentration of high mountain lakes and ponds in the Sierra de Guadarrama.

Charca de alta  montañaAt the Peñalara Massif there are several wetlands with a great interest and ecological value, which origin is linked to the glacial activity of the last glaciations period. Among all of them we should emphasize the Peñalara Lake (La Laguna Grande de Peñalara) due to its size and location at an extraordinary beautiful cirque. There are however other of less entity such as The Birds lake (La Laguna de los Pájaros) and The Carnations lake (La Laguna de Claveles), and numerous ponds and peat soils disseminated all over the massif. This high-mountain aquatic ecosystems richness has allowed the Peñalara Massif Wetlands inclusion as a Ramsar Site on the list of wetlands of international relevance.

When those lacustrine enclaves are located sporadically in a region, they reach a remarkable representative degree and even an emblematic character, very often proper of other latitudes great lakes. That is the case of The Peñalara Lake, one of the Sierra de Guadarrama National Park visitors’ favorite destinations. In the past that lake suffered an important damage due to an inappropriate tourist use, leading to the accomplishment of a relevant ecologic restoring project. At the present time this enclave visit is limited in certain aspects to maintain its ecological status in excellent conditions.
