Redes is a land of water, forests and mountains. It is a territory of steep relief, with altitudes that range from the 2,104 meters of the Pico Torres, to the 350 meters at which the Nalón river runs in the lowest point of the territory. In addition, the park occupies one of the areas with higher environmental value in Asturias and the north of the Iberian Peninsula. About forty percent of the territory is covered by forests, mainly of beech, but there are also oak, birch, chestnut, etc.
In the park you can still find all the characteristic fauna species of the Cantabrian Mountains, such as capercaillie, golden eagle, black woodpecker, wolf, marten, etc. Along with these species, there are chamois, deer or wild boars in great number, hunting species for which the Redes Hunting Reserve is well renowned.
