Idyllic circular route in the Osterseen nature reserve.
Part of the route leads through the forest along rooty paths. The landscape was created by the Ice Age and there are still numerous spring pools, such as the "Blaue Gumpe", from which the lakes are fed with groundwater. There is a designated bathing area at both lakes - jumping into the water is prohibited outside the bathing areas. The hike is signposted with green and the number 23.
There are refreshment stops along the way.
Highlights:
- "Blaue Gumpe"
- Swimming opportunities
