Tingdalsøerne is the overall term for the lakes of Rævsø, Grane Langsø, Kalgård Sø, and Kongsø. The lakes are primarily surrounded by plantation and moor.
As they are extremely sensitive to human impact, the lakes and their surroundings have been declared protected, and you therefore cannot walk on the bare banks or bathe, fish, or go sailing in and on the lakes.
However, Torup Sø lake is a regular lake where bathing is permitted at the eastern lakeshore.
Signs are posted in the area.
