The area covers approximately 594 km² and was designated a nature park in 1998. The region is characterized by extensive pine forests, moors, rivers, and, above all, an exceptionally high density of lakes. In total, there are over 100 lakes with an area of more than one hectare, most of which are connected by the Dahme River. Today’s landscape was mainly formed during the last ice age: glaciers carved out valleys, depressions, and terminal moraines, in which numerous lakes later formed. The region is often referred to as “Dahmeland” and is one of the most popular nature and water landscapes around Berlin.
The nature park is characterized by a varied combination of lakes, dense forests, and wetlands. Many of the bodies of water are connected by small streams and watercourses, forming a widely ramified water and nature system.

The many bodies of water also make the area a popular destination for water sports. Numerous waterways allow for canoeing, sailing, or houseboat tours through the lake landscape. Thanks to the interconnected rivers and lakes, it is even possible to travel a long water route: via the Dahme, you can reach the Spree, then the Havel, and finally the Elbe to the North Sea.
The Dahme-Heideseen Nature Park is an important protected area for numerous rare animal and plant species. The lakes, moors, and wetlands in particular provide valuable habitats for many specialized species. Among the best-known animals in the region are otters, which need clean waters, and ospreys, which regularly breed here. Rare bird species such as the black tern can also be found in the lake landscapes. Amphibians such as crested newts and fire-bellied toads also live in the wetlands.
