Wulai hot springs, in Wulai District of New Taipei City, produce weakly alkaline carbonic acid water at temperatures of 55 to 80 degrees Celsius.
The hot springs of Wulai produce mineral water in abundance and were developed long ago; the very name Wulai, in fact, is said to have come from the Atayal aborigine word for "hot springs." The water is clear, colorless, and odorless; it is said that bathing in it keeps the skin moist. Wulai boasts the largest free-of-charge hot-spring area in Taiwan. It is especially popular in early spring, when red cherry blossoms fill the mountainsides so that visitors can enjoy the beautiful scenery as they soak in the hot springs and bask in the romance of the Atayal aborigines.
