Lakes and moors on Bornholm

Many of the smaller inland lakes on Bornholm are now peat areas. This is particularly true of some of the lakes in the Almindingen area, the largest wooded area on the island. Other lakes are covered with grass and reeds and water lily. Smaller water areas are completely covered with vegetation. Almindingen area - the largest forest area on the island. The remaining lakes are covered with grass, reeds, and a water lily. The smaller water areas are completely covered with vegetation.

Roso Lake, located within the wooded Rø Plantation, is a body of water that is overgrown with a small pond rose. The lake is not only botanically valuable as the vegetation creates optimal retreat areas for the freshwater fish that inhabit it.

Hammersø Lake at the foot of the Hammeren plateau. It is situated near the coast in the north of Bornholm, between the Langebjerg hills and the granite cliffs of Hammeren, and is almost 700 m long and about 150 m wide.

Lake Opalsø is right next to it. Both of these water bodies are artificial lakes and are the remains of former granite quarries, which were flooded with freshwater after their closure. A rope is installed above Lake Opalsø, on which you can slide down from the plateau and land in the lake. It takes some courage to participate in this game.

Many of the lakes on Bornholm are the result of human activity. For example, in the course of coal mining south of Hasle a deep water vein was discovered, which has since supplied water to Lake Rubinsø.
The nearby lakes Smaragdsø and Safirsø were also created by mineral extraction on the island, and are named after the colors they flicker when the sun shines.
Individual lakes have their own names, such as Stenbrudso, which was created when an old quarry was flooded. In the 19th century, deposits of granite and gneiss were mined here. The mining heritage includes lakes, some of which are deep with mostly irregular soil structures.
