The caves are very interesting. There's not much to see but still its interesting, especially when one considers that the caves were inhabited 500 thousand years ago. Apparently neanderthal fossils were excavated in the caves. We went in august when antalya is 40degrees. The walk up to the cave is a very steep 300 meters. Wear runners, no flip flops. And take a headlamp or flashlight as parts of the cave were dark. And take plenty of water!
