For anyone that likes to visit "heaps of rubble", but have seen all the usual sites, try Kibyra just outside of Golihisar. Though technically not open to visitors,so no entrance fees, I spent today with friends visiting the site, which currently comprises running track with seating for 10,000, amphiteatre, odeon, agora, & two sets of Roman baths. There is allegedly the largest mosaic in Turkey.
To get there, take the mountain road to Antalya & about halfway between Kemer & Korkuteli, take a LH turn towards Golihisar, following the brown signs.
