At the eastern end of the Gredos mountain range flows Iruelas stream from which the valley takes its name. A small yet unique area that boasts a wealth of flora, with more than 600 recorded species, including ancient black pines. Its fauna is equally worthy of note, as it is home to the largest colony of cinereous vultures in Castilla y León. Indeed, the area has been declared a Special Protection Area for birds, and the Iberian imperial eagle can also be seen here

Declared a Nature Reserve in 1997, the valley runs from the peak of Mount Escusa to the Burguillo reservoir; nearby, visitors can explore a restored village of resin workers. The spectacular landscape is dotted with waterfalls, gorges and valleys, making this the ideal choice for adventure tourism activities, or simply relaxing and enjoying the breathtaking views from the Puerto de Casillas viewpoint.
