Freibad Letzigraben is a city outdoor pool designed by writer and architect Max Frisch in the late 1940s, set in park-like gardens beside Letzigrund stadium. Older kids swim the 50-meter pool, ride the wave pool and jump from a diving tower up to 10 meters. Younger ones get a current channel, water play, a small slide, a shaded paddling pool and a playground.
