Very crowded and busy at the lakes. If you walk a few steps further, you'll find peace from the masses. A short hike away from the lakes is worthwhile

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.
