Stadtbad Tiergarten

This is a very nice facility, but it was quite crowded when I went at about 10:30 on a Tuesday morning. There were no lane speed designations, but it featured a clever hack that helped with passing challenges. Two adjacent lanes were made into "one way" lanes, so faster swimmers passing others could have their own space without worrying about someone coming from the opposite direction. The lane lines were raised about six feet above deck level at each end, so swimmers could easily move over to the adjacent lane going "back", though doing flip turns with this set up isn't practical. Be sure to check the website, as the schedule for public lap swimming differs by day.

As this is a 50m pool there are more serious lap swimmers here than in other locations. One lane is reserved for fast swimmers.

Unfortunately they prioritize schools and clubs in the rush hours, so it can get very crowded those evenings.

A good option in central Berlin. Very clean and excellent changing facilities. Normally not more than 10 or 15 swimmers in the three available lanes, good for lap swimming.

Caps and shower shoes not required. Lanes not speed-designated.
