Hiking around Cangas De Onís
My opinion about Lake Enol is that it is the most beautiful and spectacular of the Lagos de Covadonga, and one of the most special mountain landscapes in Asturias. 🌊 Iconic image: its deep lake, the reflected mountains, and the grazing cows create a perfect postcard. 🏔️ Sense of grandeur: it conveys more "high mountain" than Lake Ercina. 📸 Very photogenic: especially with light fog, at dawn, or after rain. 🚶♀️ Accessible: it can be enjoyed without long hikes.

Known as the "Garganta Divina", this route between Cain (Leon, Castile and Leon) and Poncebos (Asturias) offers you the opportunity to walk between mountains that rise more than 2,000 meters above the bottom of the imposing gorge dug by the Cares River. You will see mythical peaks, cross bridges that connect both sides of the gorge, go through about 70 tunnels carved into the rock and witness an amazing natural spectacle.
