Bike Touring Highlight
The nature reserve Lanstroper See is located on the territory of Dortmund in the district Scharnhorst, in the district Lanstrop. The Lanstroper lake was built around 1963 by a subsidence, which reached the groundwater level and thus ensured that this area was permanently flooded. The almost 8 ha lake is at its deepest point almost 5 m deep. The lake is surrounded by a narrow reed and reed belt, which also grow rushes, hedgehog flats, willowherb and stinging nettles. North of the lake has grown a forest and brushwood strip that provides habitat for the endangered small frog, the common frog and the common toad.
