In Spandau, there are some nice waterside running options: several km of path along the Havel River, and the Bullengraben — is a revitalized green corridor that runs along its namesake narrow canal.
Havel River Path. There’s a scenic, 3 km paved path along the Havel River. It runs from Wröhmänner Park just north of Old Spandau south to Betckestraße. There are nice views of the river most of the way. There are separate paths for pedestrians and cyclists, with the pedestrian path closest to the water.
