In the city’s rivers and Lake Zürich the water quality is impeccable, and there’s a catalogue of places to take a dip in the open air.

One, the Frauenbad am Stadthausquai is for women only, while the male counterpart is the one at Schanzengraben.

The two are centrally located and are ideal if you want to squeeze some exercise into your day.

Both of these spots also open as stylish bars on summer evenings, in a nightlife ritual that you can’t find in other cities.
