Rainbow trout is abundant in the lake. Rainbow trout can reach the length of half a meter and weigh up to two kilograms. This fish loves fresh and clean water, like this one. Growing into a grown-up one, this beautiful fish with a silver-white abdomen and a greenish back with brown spots on its sides becomes a predator. She can devour frogs, chicks, and small rodents. Trout spawns from March to May, when the Cross Lake is overfilled with water.
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.
