The Flaming Rocks Of Chimaera, Turkey

Southwest of Antalya, near the town of �覺ral覺 in southwestern Turkey, lies a rocky mountain that's been literally on fire. About a dozen flames burn on the side of the mountain fueled by methane gas that issue through the vents. The rocks have been burning for at least 2500 years.
Sailors could see the flames from sea and used them as a landmark to navigate, but today they are more often used by hikers to brew tea.
