Guguan Hot Spring, set in the narrow mountain gorge of the Dajia River valley in Heping District, Taichung, is one of Taiwan's most celebrated mountain onsen destinations, its waters discovered and developed during the Japanese colonial period when it was known as Meiji Onsen. The bicarbonate thermal waters of Guguan are naturally crystal clear and slightly alkaline, appreciated for the softness they leave on the skin and longstanding popularity with Taiwanese bathers seeking relaxation and well-being. The dramatic scenery of Guguan, with its sheer cliffs, suspension bridges over the turquoise Dajia River, and access to hiking trails in the Central Highlands, makes it one of Taiwan's most scenically stunning thermal spa destinations.
Insider tip — Guguan Hot Spring lies in a narrow gorge cut by the Dajia River in the central mountains of Taiwan, surrounded by canyon walls that amplify the roar of the river. The sulfurous water here is colorless and odorless compared to northern Taiwan springs, making it popular with visitors sensitive to strong mineral smells. Several riverside hotels offer open-air tubs suspended dramatically above the river torrent.
