Wulai Hot Spring, set in the forested gorge of the Nanshi river some 40 kilometres south of Taipei in New Taipei City, has been a celebrated hot spring destination since the Japanese colonial era, when the area's bicarbonate sodium waters were first developed for therapeutic bathing. The springs are closely associated with the Atayal indigenous people, who have inhabited the Wulai area for centuries and whose cultural heritage — including traditional weaving, music, and cuisine — forms an integral part of the visitor experience. The jungle-clad valley setting, with its waterfalls, cherry blossoms in spring, and accessible location from central Taipei, makes Wulai one of Taiwan's most visited natural spa destinations.
Insider tip — Wulai is Taiwan's most accessible mountain hot-spring village, set in a gorge where the Nanshi River cuts through subtropical forest just 40 kilometers from Taipei. The sulfurous sodium-bicarbonate water is colorless and silky, piped from hillside springs into both outdoor river-view pools and private in-room tubs at dozens of riverside resorts. The Atayal indigenous community here also offers mochi tastings and a narrow-gauge tourist railway that adds cultural texture to the soak.
