Sunday morning, we drove about 40 kms (28 miles) west to Patara Beach. I hadn't done any research into the place, and knew nothing about it other than it was a wide long beach and there were some ruins nearby.
So we were a little surprised to find that you actually have to enter the ruins site in order to get to the beach. We bought the ticket that was 30 lira ($5 CAD, $3.85 USD) in order to explore the ruins, and visit the beach. Many people come just for the beach and pay a little less.
