In the region of the Gailtal Alps, in between the Drau and the Gailtal, lies Lake Weissensee at 930 metres above sea level. The lake is 11.6 km long, 960 metres wide and has a maximum depth of 99 metres. Weissensee is the fourth largest lake in Carinthia with a total surface area of 6.5 square km.
Two thirds of the shore are undeveloped and together with a favourable climate, an exceptionally rich variety of plant life is supported.
A distinctive feature is that there is no road connection between the east and west shores, however, nature lovers can access the whole lake by walking, bike riding, or by taking the ship.
