The Cañada Real Soriana Oriental runs through the north of the municipality of Brea de Tajo through a landscape of crops and pastures of oaks with abundant stands of kermes oaks and gall oaks, making up a territory of great environmental quality of ocher and red hills populated by some centenary specimens. The route of the livestock route is integrated into several local hiking routes, it has rest areas, a point of interest with interpretive panels and several cabins from the glorious era of the Concejo de la Mesta, used for centuries by shepherds on long migratory journeys. . On the side of the road appears the Cabaña del Quiñonero, which has been rehabilitated and shows the main elements of pastoral constructions, with one floor covered by a conical vault and another rectangular room that was used to store livestock.
The path crosses the Orusco de Tajuña highway and enters a terrain of slides populated by dense forests of oaks and gall oaks of monumental size on Mount El Robledal. In one of the valleys appears the Pozo de la Yesera, an old traditional well used by herds as a resting place. And shortly after, at the end of the next slope, are the old Corrales del Calero, like sentinels at the top of a solitary hill adorned with an ancient almond tree. By bicycle the path passes quickly, crosses the Cordel de las Merinas and immediately crosses the Carabaña road and the 40 Days Train, in this section converted into a Greenway. At the intersection there is a small rest area and an information panel. The 40 Day Train was a military railway line built in record time during the Civil War between Tarancón and Torrejón de Ardoz to supply the Republican troops fighting in the trenches of the capital. In reality, it took one hundred days to launch the line and it was known as Vía Negrín after the head of the government who ordered the construction in 1937.
