We went there early in the morning and there were nearly no people around. We walked the pathways alone, was so quiet and peaceful. Very natural, nice place to visit.
Don't expect world class water park and you'll have fun. There are slides, a roller coaster, and a lot of water. Entrance fee isn't high, bathrooms have showers, you can relax on a long chair on a grass and sunbathe if you're tired of water.
