Pine forest Abantos

Alto de Abantos (Abantos Peak). At 1,752 m., forming part of the GR-10 route, it represents one of the most emblematic places of the Madrid mountain region. The steepness of its slopes and the reforestation carried out in the past create a diversity of environments and contrasts that make it the ideal place for mountain-lovers.


You will find it on the topographical maps towards the west – north. In our general map it goes from Robledondo to the Monastery, and from there to Abantos (it goes right up to Guadarrama). To the west and north of the C-505, the town and the C-600. During the whole year it is a bluish-green and sap green mass, sprinkled in its streambeds with ochres in autumn.

Up until the end of the 19th century, this area was made up of great fields and what was left of the autochthonous forest, so diminished by the human needs of that time. Since 1892 the reforestation started thanks to the work of the Escuela Especial de Ingenieros de Montes (Special School of Mountain Engineering) and then, later, ICONA (National Institute for the Conservation of Nature).

The lower boundary of the forest, between 800 and 1,030 metres, is made up of little areas of mixed forests of pines and Pyrenean oak, with the flora associated with them.

The great majority of the trees that were used to carry out the reforestation were pines, and although we cn find up to eight different species, we can only talk about four in general.

The Scot’s, Albar or Valsain pine trees, Pinus sylvestris, easy to recognize because of its orange-coloured branches and the youngest part of its bark. The old specimens exposed to the wind and the cold have the appearance offlagpoles, that is, all the branches on one side, which shows the resistance of these trees and their capacity to adapt to the winds and the cold. The twisted appearance of the trunk, opposed to the rectilinear and cylindrical look that is developed under normal conditions, is also characteristic in the trees that grow in the rocky areas. The “sulphur” rain is characteristic at the end of spring, which is produced by their masculine flowers when they spread their yellow pollen.
