Baotu Spring is definitely worth a visit. The park is beautiful, and aside from being very crowded, it has no other drawbacks. The three springs are quite large, though the spray isn't very high. Each pool is different, and it's quite interesting to observe closely. Some pools constantly emit small bubbles, and many pools are teeming with koi. However, due to the large number of people feeding them, the fish have become very picky eaters.
