Where else can you run for five minutes with your eyes closed? Berlin's most amazing space is this historic and wide open airport just south of Kreuzberg, which closed in 2008 and was opened as a park in 2010. Now the runways and taxi lanes are used by bikers, inline skaters and kiteboarders; the fields around them are used by rare breeding skylarks (from April-July), picnickers, barbecuers, artists, kite-flyers, gardeners and dog-walkers. There's even a Biergarten at the northern end. Note that turnstiles allow exit from the park after closing time as well. Also easily accessed from U-Bahn stations Tempelhof and Boddinstrasse.
