My tip“Entry is by free permit, limited in number (about 20 people a day), requested weeks in advance from the Government of Asturias. The full trail is about 20 km and difficult, so it suits sporty families and older children.”
Spain's largest oak forest and one of the purest in Europe, a strictly protected reserve home to the brown bear and the capercaillie. Its trails pass through ancient trees and small glacial lakes.
Hard going, needs a car
Two and a half hours from Oviedo on narrow mountain roads; the visitor center is in Tablizas.
