Spree, Havel and Berlin-Spandauer Schifffahrtskanal
This is was an evening ride along the water. We left home after 16:30, the ride was about 3 hours and most of the ride is over separate cycling lane or walking paths without many people.
The route starts from Berlin Mitte/Wedding going west to Spandau along the river Spree: a bunch of bridges and many industrial sights in the first stretch.
The second part starts where Spree and Havel meet and you ride into old/central Spandau and by Spandau Citadel – an interesting historic site, I like it and take friends visitign Berlin here. Pretty ride along the newly built embankment.
The third part is a smooth straight ride along the "Berlin-Spandau" ship canal crossing some cosy tiny bridges on the way and mostly rolling by the "little garden" communities right along the once fun Tegel airport (you could be sitting on board of a plane in 35 minutes after leaving your flat in Mitte).
Beautiful route, very recommended.
