Very spring when the snow melts off the surrounding rugged mountains, park benches, flowers, footbridges, trees and walking paths disappear under water of Green lake in Austria. Crystal clear water becomes a hot spot, a fantasy land for people brave enough to scuba dive. The lake is ranked by divers as one of the top European undersea environments due to the phenomenal underwater visibility

Green Lake is surrounded by an Austrian village called Tragöß. It is a county park where hikers tromp through the lush Hochschwab mountains and forests year round.
