Sankelmarker Lake is a natural body of water from the last ice age, which is now fed by two streams and various springs on the banks and bottom. This constant supply of fresh water has ensured the excellent water quality of the relatively deep, clear lake in recent years. Ideal conditions for fishing at Sankelmarker Lake. Due to the extreme nutrient input from the surrounding agriculture, however, there is an increasingly explosive proliferation of phytoplankton in the summer months, which pollutes the water. It is then also not possible to swim at Sankelmarker Lake. The banks are largely covered with trees and very difficult to reach. There are jetties, but almost all of them belong to private property. There are a few free bays on the south bank. A boat can be launched here. Fishing at Sankelmarker Lake from a boat

A small tour takes you around Lake Sankelmark. Hiking tour "Water experience": The hiker is guided over 4.2 km for around 90 minutes, always directly on the water. Enjoy the special atmosphere of the lake and listen to the sound of the small waves. Seabirds can be observed with the observation telescope. The academy center is also worth a visit.

Here, from the hiking trail that leads directly to the edge of the forest to the lake, numerous T-shaped wooden footbridges lead down to the lake. Here you can relax your soul and your feet.
