Cleopatra Island is the best-known boat destination from Marmaris, though it lies across the water in the Gökova Gulf and is better thought of as a long and rewarding day. Properly named Sedir Island, it is a small pine-covered island with the ruins of the ancient city of Kedrai, a stretch of fine sand and clear shallow water. Local legend says that Mark Antony had sand shipped from Egypt to make a beach for Cleopatra, which gives the island its popular name, though no one can prove it. The boat trip leaves Marmaris in the morning, crosses the bay to the island and stops for swimming, then continues to other beaches and coves in Gökova before a lunch on board and a return in the late afternoon. Access to the island itself, and to the famous sand beach, has been regulated to protect the site, so what you can do on land depends on current rules and the operator. Either way, the setting is memorable.
The crossing takes a couple of hours, with stops on the way. Operators vary: some include the island entry fee in the price, some ask for it separately in cash, and some trips stay in the water rather than going ashore. Ask when you book exactly what is included and whether you will be allowed on the sand.
Ruins at Kedrai include remains of a theatre, a temple and a city wall, and they can be reached by a short walk uphill from the beach where land access is allowed. Wear shoes you can walk in, not only flip-flops.
The Gökova area is among the calmest parts of the coast, with water clear enough to see fish from the deck. A good Cleopatra day often includes two or three stops, a lunch, and a long and unhurried passage back along a coast that glows in the late-afternoon light. The product we link is a boat trip with lunch and drinks included from Marmaris, which is the practical way to go. The trip is longer than the standard bay boat day, so choose it if you want a bigger journey rather than a lazy float.
Season matters
Cleopatra boats run mainly from April or May to October, and the sea is most inviting from June to September. In July and August the island can be busy, so go early or in the shoulder months. Bring sun protection, water shoes, a towel, a hat and cash for any extras. The trip suits couples, friends, history lovers who want a few ruins with their swim, and families with children who are comfortable on boats. It is a good pairing with a walk through the Marmaris old town for the historical background.
If history is your main interest, read a little about Kedrai before you go: the city was a small Carian settlement that later joined the Athenian league, and its theatre and walls are still visible among the pines. Snorkellers should bring their own masks if they have them, as the water around the island is clear enough to reward a swim. Photographers will find the late-afternoon return crossing the most atmospheric part of the day.
