Offbeat Traveler: Green Lake in Austria

Green Lake in Austria is a popular spot for hiking that is nearly dry during the winter months. But once the temperatures start to creep up, the snow on the surrounding Hochschwab Mountains starts to melt, and water runs down to the valley. By summer, areas of the lake can be 30 feet deep, and visitors take off their hiking boots and throw on scuba gear. Divers come to check out the underwater meadow, trails, roads and bridges. It’s not every day that you can see a submerged park that’s dry half of the year.
