1. Nantie Cultural Palace has a swimming pool, which is open-air and divided into two swimming pools. The deepest point is 2 meters. You can get off at Nantie Second Street and ask people around the sidewalk how to get to the Natatorium of Nantie Cultural Palace. They will tell you. My description is a bit cumbersome, because it is not convenient to introduce the terrain there. Just get off at Nantie Second Street and ask someone. It's very close.
2. Xida Swimming Pool, on the other side of the zoo, namely the Academy of Agricultural Sciences, is open-air. It's very big, with only one swimming pool, but it's very big. From shallow to deep, you can take bus No.4 or the bus heading for the zoo.
3. Wenhua Garden Swimming Pool, take bus No.4, get off at Wenhua Garden and enter the activity center inside. There is also a swimming pool there, and the entrance fee of 5 yuan is not expensive. My understanding of Nanning is only about the above three swimming pools, and the prices are fairly cheap. I hope I can help you. Thank you.
