Streams of thawed snow do not dry out throughout the year. They always murmur, feeding the lake. When the water runs out and the air temperature rises - the lake becomes shallow, almost dry. Then frosts strike, the streams freeze, the lake freezes, and, frozen in the wizard of ice, everyone expects spring. In spring and summer, the lake is filled with water and floods the trails and benches with emerald clean and cold water, and, by the end of summer, having become shallow again, the lake repeats this ritual from year to year.
Grüner See is rightfully considered one of the wonders of Austria. The lake is often called the Emerald Lake because of the special shade of its water. Hiking trails of different lengths and difficulties are arranged along the shores of the lake. Stunning views are along these trails. Diving on the lake is one of the most unusual tourist attractions in Austria.
