• Real snow only, since the snow cannons and ski lift came down decades ago, so go the morning after a good snowfall
• The old sled run is fenced off, so pick one of the open slopes and check the runout before kids push off
• Two S-Bahn stations nearby: Grunewald and Heerstraße, then a walk through the forest to the hill

Teufelsberg is a hill built from World War II rubble in the Grunewald forest, topping out at 120 meters above sea level, the city's second-highest point. When snow falls, families sled and snowboard down its open slopes, which once had a ski lift and an official sled run.

The old run is now closed and partly fenced off. The abandoned US listening station sits on the summit.
