Cervantes is a municipality in the Os Ancares region, in the province of Lugo, whose name refers to the fact that it is a land of deer. But we can also find throughout the region other mammals such as wolves, wild boar, foxes, etc. In recent times, bears from western Asturias have also been making occasional incursions into Galician territory. A great variety of birds such as the short-toed snake eagle, sparrowhawks and goshawks are also common in these areas, as well as 27 species of reptiles and amphibians and a great wealth of flora. 

Leaving from near the Ancares hostel, where you can leave your car parked, there is a road that leads directly to the summit of Tres Bispos (1,793 m), so called because tradition has it that the bishops of the dioceses of Lugo, León and Astorga used to meet there. It is also one of the most representative peaks in the area, along with others such as Mustallar (1,975 m), Corno Maldito (1,858 m) and Pena Rubia (1,821 m).
