There is a water park here. About five slides. Two for children and three for adults. They work in turns, I don't know why. Children are not allowed to go to the deep pool, even with their parents. A lot of locals come in shorts and T-shirts, and swim, the pool is dirty.
If there are many days and you need to entertain a child, then yes, it's fine, children still like it, but not especially for adults.
