It is characterized by a permanent fire caused by methane emissions and the area is located on a track popular with hikers and trekkers on the Lycian Way. Called in Turkish Yanartaş (flaming rock), the spot consists of some two dozen vents in the ground, grouped in two patches on the hillside above the Temple of Hephaistos about 3 km north of the village of Çıralı, near ancient Olympos, in Lycia. The vents emit methane thought to be of metamorphic origin. In ancient times sailors could navigate by the flames, but today they are more often used to brew tea, the flames being of little use for navigation nowadays.
