Another of the natural wonders that the south of the Sierra de Gredos offers us, the Gruta del Águila. Underground architecture that the passing of the centuries has shaped with infinite slowness and that we can enjoy.

To get to the grotto we will cross the Jewish quarter of Arenas de San Pedro, we will skirt the castle of Condestable Dávalos and crossing the medieval bridge of Aquelcabos, we will ride parallel to the Arenal river, a tributary of the Tiétar river. Riverside forest and wide pine forests border the path that leads to the Dehesa de Los LLanos, a settlement that gave rise to the current Arenas de San Pedro.

Located in the natural pass between the Tiétar valley and the heights of Gredos we find the Barranco de las Cinco Villas, so called because in its extension there are five towns with the title of town. All retain to a greater or lesser extent much of their traditional architecture. But what is common to all of them is their natural environment, a glacial cirque with the imposing Villarejo mountains, the majestic Torozo over the Puerto de El Pico and its Roman road. This privileged situation has created an enormously varied natural environment, as well as the crops, as diverse as you can imagine thanks to its microclimate and a generous and fertile land.
