Ever swam in a lake with benches and grass at the bottom - One where you have to float through trees and dive under bridges? In fact, if you close your eyes for a moment, it almost resembles a park in your neighborhood - Which is exactly what it is, for about six months a year.

Aptly named Green Lake, this part lake, part park, is situated in a unique location at the bottom of the snow-capped Hochscwab Mountains in Tragoess, Austria. Through the cold dry winter months, when the water drains out, the park becomes a popular resting spot for people hiking the mountains.

But in spring, when the weather gets warmer, the snow on the mountain tops begins to melt and flows down into the land below, flooding the park to create an ice-cold crystal clear lake, that sports a tint of green, thanks to the grass below.

The water level rises from two meters deep at the end of winter to about 10 meters in late spring and early summer, peaking in June, before finally receding in July. This unusual phenomenon has made Green Lake a favorite destination for divers seeking unusual adventures.
