Grüner See (Green Lake) is a lake in Austria which and surrounded by mountains getting a lot snow during winder and melts down in spring. During the winter the lake is only a couple of meters deep, and the surrounding area is a typical park. When temperatures start to rise up, snow begins melting and the result is a surreal park which is left 12 meter underwater. The lake fauna even allows fish to survive among the trees and eerie abandoned park staples like benches. This amazing and beautiful underwater park is popular among the scuba divers in summer.
This natural beauty and bizarre lake is definitely in my bucket list now!
