Chengmai Hot Springs Plus is located in Chengmai County in northern Hainan, a well-watered agricultural district celebrated throughout China for its Fushan black chicken, a distinctive breed prized for its exceptional flavor and the deep black pigmentation of its skin, bones, and internal organs that makes it one of China's most coveted gourmet ingredients and a centerpiece of traditional Chinese medicinal cuisine. The county also preserves the remains of Chengmai Old Town, a historical administrative center established during the Han dynasty that represents one of Hainan's oldest settled communities, reflecting the island's long integration into Chinese administrative and cultural life despite its tropical remoteness from the imperial heartland. The hot spring waters here complement Chengmai's agricultural and culinary heritage, offering therapeutic mineral bathing in a county that balances ancient settlement history, distinctive livestock breeding culture, and the productive palm oil plantations that have shaped its modern agricultural landscape.

Insider tip — Chengmai's thermal springs sit near old rubber plantations in northwestern Hainan, where geothermal heat warms groundwater percolating through ancient basalt layers. The sodium-chloride waters maintain a consistent 42°C and are noted for their smooth, skin-softening effect. Combine a soak with a visit to the nearby Chengmai Old Town's folk culture museum for a complete local experience.
