Roll out from Parkeerplaats NSG Mäuseberg und Eulenberg and the nature reserve is already under your wheels. The route runs 79.5 km through the Polder I im Hochwasserrückhaltebecken Salzderhelden nature reserve, on past the Wasservogelreservat Northeimer Seenplatte, and through the NSG Oderaue. It's all paved, with 779 m of climbing along the way. Then it's back to where you started.
