Unbelievable....Austria's Green Lake in the Hochschwab Mountains is a hiking trail in the winter. The snow melts in early summer and creates a completely clear lake. The lake has a grassy bottom, complete with underwater trails, park benches, and bridges. So cool!
“In March, due to a natural phenomenon, Siberia’s Lake Baikal is particularly amazing to photograph. The temperature, wind and sun cause the ice crust to crack and form beautiful turquoise blocks or ice hummocks on the lake’s surface.” Photograph by Alex El Barto.
