Marmaris is a Mediterranean resort town along the Turkish Riviera (also known as the Turquoise Coast) with a busy, pebbly beach and long seafront promenade. Marmaris' main source of income is tourism. It is located between two intersecting sets of mountains by the sea, though following a construction boom in the 1980s, little is left of the sleepy fishing village that Marmaris was until the late 20th century. In 2010, the city's population was 30,957,[3] and peaks at around 300,000 to 400,000 people during the tourist season.

It is also a center for sailing and diving, possessing two major and several smaller marinas. It is a popular wintering location for hundreds of cruising boaters, is also served by the nearby Dalaman Airport. It’s known for its lively nightlife on Bar Street, which is home to open-air clubs and music venues. Marmaris sits in a valley between pine-forested mountains and clear waters, which are popular sailing and diving destinations.

Marmaris Castle, a 16th-century, stone stronghold of Suleiman the Magnificent that’s now a museum of archaeological artifacts, offers views over the city and marina. The surrounding lanes of the old town are narrow, hilly and lined with old buildings, including an Ottoman inn turned market. Beyond the city are bays and coves, some on islands best reached by boat from the marina, so gület (schooner) cruises are common. One such spot is the beach at Sedir Island, which is also called Cleopatra’s Isle because Cleopatra and Mark Antony are said to have swum there.
