Is it possible that a popular lake in Tragoess, Styria in Austria is Atlantis? Na, but it is really cool nonetheless. The diving spot is also a popular hiking spot for locals. Yeah, trippy, we know. 
The Green Lake (Gruner See) is an odd phenomenon simply because under water it looks like a regular meadow with benches, roads, bridges and plant life galore. There are not many places where you can see a school of fish swim down an access road or through the branches of trees.

What accounts for this weird world preserved in water? Every year clean, emerald green water comes from the snowmelt off the karst mountains. During the winter the lake is only one to two meters deep and the surrounding area is used for nature walks and hikes. During the summer (mid May to June) the lake can reach up to twelve meters deep. In July the water starts to evaporate again.

The pictures are truly a sight to behold. Take a look, and live vicariously through the lucky guy in the video who got to traverse this faux Atlantis.
