Puerto de Casillas – Entrance to the Valle de Iruelas Nature Reserve
Highlight • Mountain Pass
The port of Casillas is one of the entrances to the Valle de Iruelas Natural Reserve, where if we choose a clear day, we will be able to contemplate a wide landscape, not only a large part of the Natural Reserve with the Burguillo Reservoir in the background over the waters of the Alberche river, but also the Sierras de la Paramera on the horizon and the first foothills of the western Madrid mountains.
