Those looking to go swimming in Kraków will be best served by doing so in a hotel (of which the pool in Hotel Stary - C-2, ul. Szczepańska 5 - is among the best in the Old Town and open to walk-ins). This is due to the fact that most swimming pools in Kraków are regularly used by schools and fitness clubs making their opening hours to the rest of the public almost impossible to divulge. For a sure bet head to Kraków's Water Park. Note that in the warm months, the most popular outdoor swimming locations for locals are the Kryspinów Lagoon and Zalew Bagry.
