Marmaris is a port town and tourist resort on the Mediterranean coast, located in Mugla Province, southwest Turkey, along the shoreline of the Turkish Riviera. Marmaris' main source of income is tourism. It has an exceptional location 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 town's population was 30,957, and peaks at around 300,000 to 400,000 people during the tourist season. It is also a centre for sailing and diving, possessing two major and several smaller marinas. It is a popular wintering location for hundreds of cruising boaters, being also served by the nearby Dalaman Airport.
