Sanya Hot Spring Forest Park, in the tropical resort city of Sanya at the southern tip of Hainan Island — China's 'Hawaii' — draws on sulfate thermal waters in a lush tropical forest setting that creates one of China's most climatically distinctive hot spring experiences: outdoor thermal soaking in year-round tropical warmth, beneath coconut palms and tropical hardwoods on China's southernmost major island. The naturally warm sulfate waters, emerging from the geothermal activity of the Hainan volcanic system, are used in resort-style therapeutic and recreational bathing within the growing luxury wellness tourism infrastructure that has made Sanya one of China's most internationally recognised spa and beach destinations. The surrounding Sanya landscape of white sand beaches, coral reefs, rainforest nature reserves, and the extraordinary cultural heritage of the Hainan Li and Miao ethnic minorities — including ancient tattooing traditions and the traditional boat-coffin burial practices recorded in the Wuzhi Mountain wilderness — gives Sanya Hot Spring Forest Park a tropical cultural depth beyond its beach resort reputation.
