Nordic Spa Kraków is an outdoor saunarium on the shore of the Kryspinów reservoir in Cholerzyn, inside Wakepark Kraków just west of the city. Two free-standing wooden saunas for ten people each have panoramic windows onto the water, beside two large hot tubs, and guests cool off with a dip in the lake. A shared 90-minute session costs 89 zł, and a sauna with a tub can be booked privately. It runs in seasons and hours vary by time of year, so check before visiting.
