Baihe Dist., Tainan City 732, Taiwan (R.O.C.)
Water and Fire Cave is one of the seven natural wonders of Tainan and has been voted one of the eight must-visit sceneries there too. Located in the village of Guanziling, in Tainan City’s Baihe District, this is a strange geological phenomenon where fire and water emerge from the same cave at the same time, making it look as though fire is burning on water. The incompatibility of water and fire make this cave amazing. You might not even believe it is real fire until you feel the heat from it as you approach.
While it seems like magic, this phenomenon can be explained. Taiwan has many fault lines, of which the Liuchong River fault runs through this particular area. Small bubbles of methane gas emerge from the fault line, lighting a fire between rocks where water also runs. Visiting the cave, you can see the gas bubbles in the water if you look closely. Also visible around you are sausage trees which grow uniquely shaped fruit but can’t be eaten because they are poisonous. Also situated nearby the cave are several vendors, from whom you can buy food and drinks. Some say the flame here has been burning continuously for over 300 years, discovered by a monk who chanced upon it in 1701. Regularly called one of the most extraordinary sites in Taiwan, this is absolutely not to be missed.
