出火位於恆春鎮東門外，是地底天然氣由泥岩裂隙溢出，點火後燃燒後至今不熄，蔚為奇觀，當地人引述，原為中油鑿井挖至泥岩層時，意外發現有天然氣自然冒出，適於夜晚前往觀賞。
Chufor, located outside the east gate of Hengchuen, is so called because nature gas that comes from the fissure of underground mudstone is able to ignite fire that make the place looks like “fire coming out of ground” (so is the Chinese meaning). The landforms here are mudstone that has many fissures; therefore, the fire would move about. Anyway the present site of Chufor is not the original one, It was moved some place from another.
