Yǎ Dīng Wēnquán, in Yilan County, northeastern Taiwan, offers sulfurous water at 35°C (pH 6.5). The venue has both an indoor bath and an outdoor rotenburo-style bath.
Insider tip — Nestled in the quiet Yilan valley near Taiwan's northeast coast, this sulfurous spring offers a more understated alternative to the famous Jiaoxi resorts nearby. The cooler temperature makes it ideal for longer soaks and is particularly soothing for skin conditions. The surrounding rice paddy landscape provides a serene pastoral backdrop unique to this part of Taiwan.
