We meet just outside the park on the bridge, opposite to the Gesundbrunnen station.
Flat is history! In the Volkspark Humboldhain you will be greeted by many ups and downs in various shapes and forms. Twisty stairs, steep slopes, long hills, and so forth... all like they were made for short and intense workouts. Plenty of wide grass areas and other park features (playgrounds, walls, benches, etc..) will provide lots of variance for a well balanced training.
