Ice Rinks, Sledding and Winter Break in Berlin, 5 of 12: Insulaner Sledding Hill

The Insulaner is a 78-meter hill built from World War II rubble, now wooded and crossed by footpaths. After a snowfall its west side holds one of the city's longest sledding runs, about 220 meters, with a smaller beginner slope at the bottom for younger kids.
The Wilhelm-Foerster observatory sits on the summit, the Planetarium am Insulaner at its foot, and there is a mini golf course on the hill.
