Mount Chimera or Yanartash is a mountain on the slope of which natural fire burns 365 days a year. In a small area, natural gas constantly comes out of its slope. This is ordinary methane, with an admixture of a substance that ignites in air. Several dozens of such torches are constantly burning there. This place has been known since ancient times and the gas has been burning for at least the last few thousand years.
Torches sometimes change their intensity and the place of burning sometimes fades, some light up again.
A small stream flows along the slope, which sometimes extinguishes some torches. A path paved with stone goes down the slope to the place of burning of torches. The entrance to the mountain is paid.
According to legend, the Greek hero Bellerophon, the son of the Corinthian king Glaucus, marries the daughter of the Lycian king Iobates and frees the inhabitants of Lycia from the fire-breathing monster Chimera. This Chimera he defeated and buried just in this place on the slope and that is why the fires appear coming out of the ground.
