I have been to Cleopatra Island (Sedir) for a long time, I was very impressed with the island's beauty, historical place, ruins, clean beach, sand. We took an excursion from Marmaris.
There are so many tourists on Cleopatra Beach that you don't have to take a camera, anyway, nothing will be visible because of them. And the rest, as promised by the guides, is very beautiful, hot and sunny, history is underfoot.
