Yanggu Wenquan — 'Sun Valley Hot Spring' — is a naturally sulphurous geothermal spring in China, its poetic name evoking a valley that catches and concentrates the sun's warmth, enhancing the geothermal warmth of the mineral spring with the additional heat of a sun-drenched topography. Sun-facing valleys in China's mountainous regions are prized for their agricultural productivity and favourable microclimate, and a hot spring in such a valley combines the abundant natural warmth of both geothermal and solar energy. The spring provides naturally sulphurous, warm mineral water in a sun-warmed valley setting of exceptional natural comfort and brightness.
Insider tip — Yanggu Wenquan sits in Ruisui Township, a well-known thermal bathing hub in the southern part of Hualien County's Rift Valley where sodium-bicarbonate-sulfur springs emerge along the valley floor. The springs here have an unusually smooth mineral quality — locals and visitors alike prize the silky sensation on skin after soaking. The Xiuguluan River, famous for its whitewater rafting, runs close by, and the combination of river adventure in the morning and hot spring recovery in the afternoon has become a signature Ruisui experience. The surrounding Amis indigenous villages add a distinct cultural dimension to the area's appeal.
