At the far end of Çıralı, an evening scramble up a sometimes steep path will bring you to the Chimaera, named after the ferocious fire-breathing beast of legend. Flames can still be seen rising from cracks in the rock, apparently also burning the gas deep below, since they reignite even if covered. In times past, the flames were apparently more vigorous, even visible by sailors offshore. The Chimaera is inland from the far southern end of of Çıralı; take either of the main roads to the end, and then head inland. If you're staying in Olympos it's a 7-km (5-mile) 90-minute walk, so you may want to drive to the bottom of the hill or take a tour. From the parking lot it's a half-hour walk up a lot of stairs. Most hotels in the area will arrange a tour. You can see the flames in the day, but they're best at night. Bring a flashlight for all those stairs, since there's no lighting, and in peak season go as late as possible to avoid the crowds.
