Guanziling is the peak of Zhentou Mountain, Tainan City. The mountain was the residence of Pingpu Tribe until 1898, when Japanese soldiers found a hot spring and developed the area. Guanziling Hot Spring is a famous hot spring in southern Taiwan. The spring water is dark gray and bitter, emerging from the rocks.
Guanziling Tourist District is famous for the hot spring, Hongye Park, Daxian Temple, Biyun Temple and Xiangong Temple. The hot spring is on the side of the mountain, where hotels, restaurants and spring pools can be found. The natural gas and the spring water exist together in the cave, presenting a peculiar view.
