Lake Niehuuser – also called Niehuussee – is located in the municipality of Harrislee in the Schleswig-Flensburg district, directly on the German-Danish border between Niehuus and Padborg. Nestled in a charming natural landscape, it is a beautiful local recreation destination and invites you to take leisurely walks around the water. The lake is part of the cross-border Krusau Tunnel Valley, a gently rolling landscape with damp valley floors, springs, and alder swamp forests that stretches along the border river Krusau. Accordingly, the area is part of a FFH conservation area and therefore enjoys a high ecological protection status. Visitors can enjoy pleasant hiking and circular trails – such as a 5.6 km route around the lake, which can also be found as a circular hike on platforms such as RouteYou. The western side of the lake already marks the border with Denmark, giving the walk a particularly charming, border-oriented perspective. The lake is particularly popular with photographers – it is considered an atmospheric subject, especially in the evening with its charming light. Furthermore, the ASV Petri Heil Flensburg is committed to accessibility: a barrier-free jetty was recently built, making access to the water easier.

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.
