Sanya Nantian Hot Springs sits on China's tropical island of Hainan, at the same latitude as Hawaii, offering a unique combination of equatorial beach destination and geothermal thermal resort. The springs, flowing from granitic bedrock at 92°C, are one of China's highest-quality natural spring sources by mineral purity, prized in Traditional Chinese Medicine texts since the Tang Dynasty for their ability to 'harmonise qi and clear heat.' The resort complex includes more than 60 open-air thermal pools landscaped within tropical gardens of palms, hibiscus, and frangipani, fed by the naturally soft, silica-rich water. Located just 15 km from Sanya's Phoenix Island cruise port, Nantian is the most directly accessible of China's major thermal resorts from the sea.

Hainan's hot springs appear in Tang Dynasty geographical records from the 7th century AD, described by court geographers as 'southern fire waters' accessible only after long sea voyages. The spring at Nantian was developed by the Li people — Hainan's indigenous population — as a healing site, and their traditional uses of the spring for skin ailments and childbirth recovery are documented in Qing Dynasty ethnographic records.
Hainan's hot springs carry the cultural weight of China's 'li'ao' tradition — the idea of a healing journey to a remote and beautiful natural place. In contemporary Chinese culture, Sanya represents the ultimate relaxation destination, combining tropical beach luxury with traditional wellness, a combination that has made it the country's fastest-growing domestic tourism destination. The practice of outdoor tropical thermal bathing — unique to Hainan among China's spring resorts — has its own rituals: bathing at dawn with coconut water drinks and traditional Li herbal compresses.
Hainan provincial government designated the spring catchment area as a protected geological reserve in 2010. The resort operates under a closed-loop water management system where cooled spring water is returned to the groundwater via injection wells rather than discharged to the sea. Solar thermal supplementation heats ambient pools during cooler months, reducing direct draw from the hyperthermal source spring.
