Located in Nantou, Taiwan, the Riyue Tan Hot Springs offer a unique thermal experience. The spring's water is bicarbonatated, providing a relaxing soak. Inspired by China's Lushan mountains, this hot spring resort invites you to unwind in natural beauty.
Insider tip — Riyue Tan Hot Springs sit on the North China Plain near Nanyang, drawing bicarbonate-rich geothermal water that emerges at a steady 40°C from deep sedimentary layers. The resort sprawls across landscaped grounds with pools shaded by willow trees, particularly atmospheric in early morning mist. Henan winters are biting, making the warm pools especially coveted from November through February. Weekday visits avoid the large weekend crowds that arrive by bus from Zhengzhou and Wuhan.
