Ruifang Jinguashi Hot Spring draws on chloride-rich thermal waters in one of Taiwan's most dramatically scenic historic mining districts — Jinguashi, a former gold and copper mining town clinging to fog-shrouded coastal hills above the Pacific in New Taipei City. The thermal springs here are geologically linked to the volcanic and mineral-rich geology that attracted Japanese mining operations during the colonial era, when the area contained one of Asia's most productive gold mines. Today visitors combine hot spring bathing with exploration of the nearby Gold Museum, the haunting former POW camp memorial, and the Yin-Yang Sea — a naturally bicoloured bay stained by iron-rich mineral seepage.
Insider tip — Jinguashi overlooks the Pacific from a ridge in the old gold-mining district of Ruifang, where residual volcanic activity feeds a hydrogen-sulfide spring that stains metal fixtures yellow-orange within weeks. The spring temperature at source can exceed 60 degrees, so pools are diluted to comfortable levels, but the mineral concentration remains notably high. The adjacent Gold Ecological Park traces the site's Japanese colonial mining heritage, adding historical depth to the thermal visit.
