Tips from locals
The one and only place to be when it's extremely hot out. You sit in the shade of a forst and dip into the lake to cool of. Take the metro U3 to station Krumme Lanke and you're just a stroll away.
Venture out of the city to the nearby lakes. This one being rather clean and surrounded by large trees. Sand bays, grassy knolls and some nude bathers.
