The Black Lake on the Baltic Sea island of Rügen belongs to the Sellin district and is located in the Granitz forest and nature reserve.
The area of the lake is 23 hectares and its greatest depth is 15 meters. The height of the lake level above sea level is 54.2 meters above sea level. The nutrient-poor lake belongs to a very rare type of water body, the so-called kettle lake. Intermediate moor and high moor formation takes place in the marginal area. Partly there is a swinging cover vegetation. Here cottongrass, sphagnum moss, cranberry, fever clover and rosemary heath occur. The entire lake, the bogs existing at the edge and a 100-meter-wide strip of the forest surrounding the lake are designated as a core zone (total reserve) of the Southeast Rügen Biosphere Reserve. For hikers and cyclists, however, the lake is accessible via the hiking trail leading from Binz to Sellin. You can reach the lake via a small wooden footbridge.
