Mingcheng International Hotel Swimming Pool, Kaiyuan Xincheng Hotel Swimming Pool, Venetian City Swimming Pool, He Long Sports School Swimming Pool, Changsha University of Science and Technology (Yuntang Campus) Swimming Pool, etc. These swimming pools have a good environment, including Mingcheng and Kaiyuan New Town, but the fees are expensive. Personally, I recommend going to He Long Sports School. The charge is cheaper and the environment is OK.
