Termy Maltańskie is a large swimming and sauna complex beside Lake Malta. It combines sports pools, water slides, wave pools, saunas, and summer outdoor pools, making it one of Poznań's easiest family or bad-weather stops.
The different zones are ticketed separately, so decide before entering whether you want the aquapark, swimming pools, saunas, or a combination. Evenings, weekends, and hot summer days can be crowded.
