If you like swimming, this little gem is just down from the Zurich, on the left side as walk down stream. Trams 2 and 4 stop at Kruzstrasse from where it’s a short walk down to the lake. It’s not a swimming pool in the conventional sense but a number of wooden jetties built out over the lake. There are steps leading down from each jetty into the water. There is no shallow water, it’s just straight in to the lake, so it’s not suitable for children or non swimmers. There are two pontoons about 50m offshore, ideal for basking or jumping in. Even at the end of September the water was a comfortable 20 deg. C. The staff are very friendly, and speak English much better than my German. Don’t worry if you didn’t bring a towel you can hire one for 20CHf, refunded when you leave. The clientele might be a bit older than you expect, I guess from, 30 ish to very old. There is lots of space for sun bathing, but as a tourist you just to swim and get back o touristing.
