This is Green Lake in Tragoess – Austria.

In a valley of the Alps the Green Lake is less than a meter deep. For most of the year you can take a walk on the lanes around the beautiful lagoon, cross the little bridges and enjoy the mesmerizing view, sit on the benches or even have a picnic on the lawns around the lake.

Sounds like any other park, but from May to the end of July when snow starts melting the shallow 1-meter-deep lake can reach dept of over 11 meters and cover the whole park in water. For a few months this surreal aquatic environment becomes a favorite destination for divers and underwater photographers who are not put off by the cold temperatures of under 8 degrees Celsius.
