The waters of the lake are right by the foot of the snow-capped Hochschwab Mountains, in Tragoess, Styria. During the winter, the park is just like any other, i.e. dry and fit for baby land animals. But during the summer, the snow and ice on the mountains melt and turn the park into an UNDERWATER rite of passage to becoming a cool human being. That is, you can SCUBA DIVE through it!
