One of the most impressive sites in Spain is, without a doubt, the Lakes of Covadonga. Located in the heart of the Picos de Europa, they are a must stop for nature lovers.
After going up a narrow road from the Sanctuary and Basilica of Covadonga, the traveler finds lake Enol, the biggest of the two. It is more than 1,000 meters above sea level and very close to the coast.
For sure it is a must see.
