Built in 1907 and converted to a bathhouse in 1950, this is Taiwan's oldest operating paid hot spring. The small nude pools are segregated by sex and the facilities show their age, but the stone is original and contains hokutolite, a weakly radioactive crystalline substance found only in Beitou and Japan. Bathing here is not an experience for everyone, but many travellers enjoy it very much.

The water is a scorching 42°C degrees. The owner says no one can take more than an hour in his pools.
