Sanya has Pearl River Nantian Hot Spring, Garden Fish Hot Spring and Lijing Hot Spring. I suggest you go to Nantian Hot Spring. It is quite comfortable to soak in hot springs after a day's travel. Nantian hot springs have the highest frequency. Nantian hot spring contains many minerals and trace elements beneficial to human health. It belongs to medical fluorosilicone hot mineral water, which is not only beneficial to skin health, but also has a good influence on the body of various systems in the body, and can well adjust the tension of human autonomic nerves, improve physical fitness and enhance health.
