Olympos

The "town" area is a collection of backpacker guesthouses and hostels, particularly popular are the treehouse style bungalows. Follow the dusty road down past the end of the guesthouses and it leads to an ancient winding path, past the remains of ancient Greek ruins and down to the sparkling water. It's a pebble beach with absolutely no shade, so it's blisteringly hot to sit on and not very comfortable without thick padding, but the scenery is spectacular.

The ruins themselves are quite impressive, not as much so as Ephesus but still worth seeing. The relative lack of tourist traffic compared to Ephesus means the site is largely overgrown, which gives the place a "mystical" feel, so you have to do some hiking to get to some of the remains. I was there in late May and it was already brutally hot, so be prepared with lots of sunscreen and water.

Entering the ruins cost 5 TL/person, and going to the beach requires entering the ruins and the staff at the gate make no distinction between someone visiting the ruins and a beachgoer, so you'll have to pay this fee each time you're going to beach, except, of course, late at night and very early in the morning, when the office is unmanned. There is also the option of buying a weekly pass which costs 7.5 TL and for 10 entrances to the ruins, and thus the beach.
