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.

El Porru la Cabrona is a very tough climb on the climb to the Lakes of Covadonga, known for its demanding gradient that tests even the strongest cyclists. It's one of the legendary sections of this climb.

Although it is called Roman, its construction dates back to the High Middle Ages, probably the 13th century. There is a high probability that it was built on earlier Roman foundations. Whatever its date, the Cangas Bridge is one of the most emblematic monuments of Asturias. The river below the bridge is often quite deep, and swimmers can be seen jumping from the surrounding rocks.
