Known in Turkish as Yanartaş or 'Burning Rock', the Chimaera is a cluster of flames that blaze spontaneously from crevices on the rocky slopes of Mt Olympos. At night it looks like hell itself has come to pay a visit, and it's not difficult to see why ancient peoples attributed these extraordinary flames to the breath of a monster – part lion, part goat and part snake – which had terrorised Lycia.
Today gas still seeps from the earth and bursts into flame upon contact with the air. The exact composition of the gas is unknown, though it is thought to contain methane. Although a flame can be extinguished by covering it, it will reignite close by into a new and separate flame. At night the 20 or 30 flames in the main area are clearly visible at sea.
