If you prefer a swimming pool to a river or the lake, try the open air pool Letzigraben. There are three big pools and lawns for sunbathing. One of the pools even has artificial waves, to make you feel you’re elsewhere. The pool was designed by Swiss writer and architect Max Frisch and opened in 1949. It was completely renovated in 2007 and is frequented by many families. For those brave enough it features a 10-metre diving platform.
Open daily 07:00 - 20:00 no matter the weather (May 11 until September 15, 2019).
