Along the way there are panels with information about the cliffs and ledges that seem to collapse onto the path. Some signs are faded from sun and rain and are hard to read. They speak of the aesthetic value of the Jarama aljezares, of the rock fauna that nests in the hollows of the walls and of the flora that dares to take root in the fragile and shiny sheets of plaster, such as esparto grass and its procession of thyme, jabunas and ontines. Before completing the ascent, a fork appears that is taken to the right to access the Soto de Bayona viewpoint, an extraordinary panoramic point to contemplate the lower Jarama basin and make an interpretation of the environment. The riverbed draws the forest arch that surrounds the Soto de Bayona and forms a beautiful blue line in the battered surroundings of the valley. Behind the poplar trees and poplar groves on the opposite bank appear the rubble dumps of the gravel pit that is drilling the subsoil of Soto de las Arriadas, where the largest wetland in the Southeast Regional Park is located and one of the most valuable fluvial ecosystems, an incomprehensible contradiction but the view does not deceive. In the distance lie the endless corn fields of Ciempozuelos and San Martín de la Vega, a green carpet that reaches the foot of Mount El Espartal, a reserve of native flora next to the Cañada de los Cerros, the current name of Roman road 29 of the Antonine itineraries, which runs through the southeast of the region from Toledo and has archaeologists clueless about the exact location of the important Roman town of Titulciam, a strategic junction of several Roman roads that according to experts may be located in somewhere between Las Rozas and Móstoles. Below the viewpoint is the Cueva de los Vascos, of pre-Roman origin and used as a bunker and a lookout post during the Civil War.
