We took a chance on visiting here whilst in Brno and loved it. There were lots of different activities and it’s well maintained and clean. I’d recommend bringing swim stuff/a change of clothes and towels to really make the most of the outdoor area. Restaurant served good, well priced food and although the menu was only available in Czech staff were happy to help us out with translation. Very young kids have slightly less to do as they can’t use the bigger climbing stuff, but still plenty for a couple of hours. Highly recommend!
