In Jiaoxi, a well-known hot-spring town in Yilan County, Taiwan, Yuweigou Wenquan Gongyuan features bicarbonate sodium-chloride water at 45°C (113°F) with a pH of 8. Indoor and outdoor rotenburo baths, a sauna and massage complete the facility.
Insider tip — Jiaoxi (礁溪) is one of Taiwan's most celebrated onsen areas — its sodium bicarbonate springs are mild-smelling and silky, believed excellent for skin. The town's main street has public foot bath parks (gongyuan) where visitors soak tired feet for free year-round; the Yuweigou Spring Park is popular for outdoor bathing surrounded by Yilan's lush subtropical vegetation. Jiaoxi sits in the Lanyang Plain, with the Central Mountain Range behind and the Pacific Ocean 15 minutes ahead — a geothermally rich valley of extraordinary natural beauty.
