Watch the Rocky Ground Burn Like Magic (and Pop Some Popcorn)
The ChuHuo Eternal Flame (恆春出火) just outside of Hengchun in the far south of Taiwan
is definitely worth a stop. Natural gas seeps up from the earth and ignites on this otherwise dead area of rock and sand ground. There are several areas of fire to see and, on at busy times, there are vendors in the parking lot who will sell you popcorn to pop over the eternal flames.
