It's not too big, but there's a children's playground, and the slide is quite interesting.
Bring your own swimming ring, there's no rental, but you can buy one inside, about 38 yuan each. There are snacks for sale inside, the prices are a bit more expensive, grilled sausages are 6 yuan and 8 yuan, ice cream is 10 yuan, Baisuishan is 5 yuan a bottle, and there's free hot water inside for drinking.
It says you can't bring food or drinks inside, but many people bring their own, and no one cares. Many outdoor pools are closed.
There seem to be a few safety guards, and I didn't see them very often.
