What defines riding in Berlin?
Berlin's historic center sits where the Spree narrows within the Warsaw, Berlin Urstromtal, a glacial valley carved between the Barnim and Teltow plateaus. The Havel widens into a chain of lakes to the west, giving this dense capital an unexpectedly riverine and watery character. Six groups of Modernist housing estates here carry UNESCO World Heritage status. Summers are warm with daytime temperatures typically in the low 20s, peak comfort for exploring the city.
