Wanning Hot Spring Resort on the eastern coast of Hainan Island, China's tropical southern province, draws from geothermal springs heated by the volcanic activity underlying this tectonically active section of the South China Sea coast, where the mountains of the island's interior descend steeply to narrow coastal plains and turquoise waters. The sodium-bicarbonate spring water is used in open-air pools and resort spa facilities that blend Chinese balneological traditions with the tropical leisure culture that makes Hainan China's premier beach destination, often described as its Hawaii or Maldives. Wanning's coastline is also celebrated among China's surfing community for Riyue Bay, which hosts international competitions and has helped establish the region as a progressive tourism destination beyond conventional spa wellness.

Insider tip — Wanning Hot Spring Resort sits on Hainan Island's eastern coast, where granite outcrops meet a tropical shoreline of coconut palms and surf breaks that attract both bathers and wave riders. The sodium-chloride spring water, drawn from coastal granite aquifers at 40°C, feeds open-air pools set amid lush tropical gardens facing the South China Sea. Wanning is simultaneously known across China as a surfing capital, making it a rare destination where thermal soaking and surfing share the same coastal strip.
