Water Park for a lot of fun!
I didn’t go for a while so it will not be the most updated comment but I used to go there at least twice a month last year and I imagine there was not so much changes. I enjoyed it every time and even more during the week when there are less children.
This is a really nice and enormous place, very clean and safe. You have a quantity of different slides and don’t need to queue so much to get there. This is definitely the biggest swimming pool fun area in Krakow and a perfect place to enjoy your afternoon, no matter what the weather looks like.
Indeed you have an outdoor area with a main swimming pool and a few slides but the most fun is indoor as you have the longest and fastest slides! You can also enjoy a Jacuzzi, a spa, a kind of bath with speedy waters which is really fun(hope that sounds right in English..), solarium, cafeteria with coffee and snacks.
The place is located 20 minutes bus from the center of Krakow and you have also near by a massive supermarket and a big cinema. The adress is Dobrego Pasterza 126.
Cloakrooms are clean and the staff is nice, it is generally opened until 10 in the evening and you should know that from 7 until 10, there are really much less people and extra more room to swim.
