One thing Berliners love to do on summer weekends is to go to the lake, either for a walk or swim.
Some of the more famous lakes are Wannsee, Müggelsee and Liepnitzsee. Most lakes have very good water conditions, so it is okay to swim in them. Some of the biggest lakes have swimming facilities with lifeguards operating in a special area. Most of them also have dining options and boat rentals.
Tip: Many Germans go naked in the lakes. This is absolutely normal, especially in the eastern parts of Germany – because of “FKK”, which is short for freikörperkultur, or free body culture.
