Cuevas Del Aguila

Cuevas Del Aguila also known as the "Caves of the Eagle" ranks fifth on our list of most beautiful caves in Spain. The "Caves of the Eagle" are a fascinating underground world of stalactites, stalagmites, and columns that are all colored, making them even more stunning. The richness of minerals in the Paleozoic limestone that produced them, as well as water dripping down over millions of years, contributed to this. The cave is thought to be 500 million to 540 million years old.

The cave is situated beneath a hill covered with dense oak forest in central Spain, near the border between Castile y León and Estremadura. This helps to explain why it was only discovered in 1963. Kids have been the explorers once again; five of them were playing on the hill when they discovered steam pouring from a hole in the earth. They pushed their way through the small entryway and into the fantastic world of the Great Vault.

The caves are about 1.5 hours south of the great medieval town of Avila, which is known for its huge walls that ring the entire city. The distance between the two cities is about the same.

The cave has been exposed to the public since 1964. A guard stationed at the gate keeps an eye on security and distributes sanitary gel. The cave's approximately one-mile length is easily navigated thanks to well-lit passageways with glass walls. Be prepared for heavy humidity and perhaps slick parts along the way if you visit. The steam the kids saw was caused by the temperature difference between within the cave and outside in the cold air.
