The route goes along the valleys of two streams, La Nava and El Horco, which in the surroundings of Caballar join to give life to the Mulas stream. This area has been declared the Sierra de Guadarrama Special Protection Area for Birds (SPAB) and Site of Community Importance (SCI).

 Starting from the church of Nuestra Señora de la Asunción, we take a path along the valley of La Nava stream amongst vegetable gardens and lush riverbank vegetation mixed with fruit trees. Next to the river we can see and hear riverbank birds such as Chaffinches, Goldfinches, Wrens, Serins and Wagtails. Continuing up the valley, and after passing the singular fountain of La Fresneda, the landscape changes into low shrubs of aromatic species, and we reach a more open high plain where it is not difficult to recognize Shrikes, Stonechats, True Thrushes or Wheatears. Back in Caballar we cross the valley of the Horco stream and its dense vegetation passing through an area with caves and small crags on a little used track. Black Redstarts, Red-billed Choughs and Crag Martins are some of the species that inhabit this environment.
