Cleopatra Island (Sedir Adası) sits in the Gulf of Gökova and owes its fame to its sand. The grains are tiny spheres found nowhere else in the Mediterranean, and legend says Mark Antony shipped the sand from Egypt as a gift to Cleopatra; scientific analysis has suggested an Egyptian origin may actually be plausible. The island is a protected environmental area, reachable only on organized boat tours that limit visitor numbers, and swimming time at the famous beach is capped to protect the sand, usually at one to two hours. The rest of the island holds the ruins of the ancient city of Cedrae, including a well-preserved Roman theater, city walls, and remains from the Hellenistic and Roman periods, so bring shoes you can walk in. Tours leave Marmaris Marina around 9 AM and typically include lunch and drinks.

Marmaris has been a strategic harbor since the Hellenistic period. The castle was rebuilt by Suleiman the Magnificent in 1522 for his campaign against Rhodes. Ancient traders and modern yacht crews have used the same sheltered bay.

Visitors interested in Greek ruins and Ottoman fortifications will want a few hours here. The castle photographs best from the harbor in the late afternoon.

First-time visitors and solo travelers both manage easily here. The area is walkable, and staff at most sites are used to tourists.

Most Marmaris attractions are easy to reach from the bay. Netsel Marina sits next to the castle quarter, and İçmeler beach is a short dolmuş ride from the town center. Restaurants around the harbor serve fresh seafood.

Bazaars near the harbor sell Turkish crafts and souvenirs. Waterfront cafes are a good place to try Turkish tea between stops.
