This stunning lake is filled with water from snowmelt in March. Excess water flows through the dam into the Lyaming brook and a complex system of irrigation canals that feed the fertile valley. Rainbow trout spawns near the dam in a turbulent course, laying large eggs up to half a centimeter in diameter.
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.
