• Tram 96 to the door from Potsdam Hauptbahnhof, stopping at Volkspark right in front of the entrance
• Last entry an hour before closing, and the butterfly house stops letting people in at 4:40pm on weekdays and 5:10pm on weekends and holidays
• Summer weather all year in the humid hall, so bring layers kids can peel off on a cold winter day

Biosphäre Potsdam is a 5,000 m² tropical rainforest hall in the Volkspark. Paths wind past a waterfall and a lake with turtles and whistling geese, under trees where marmosets climb.

Kids hunt for chameleons and walking leaves, watch a huge ant colony, and try the interactive stations. The butterfly house has up to 20 free-flying species, and the Aquasphere aquarium holds corals, clownfish and surgeonfish.
