The Turkish Riviera, also known popularly as the Turquoise Coast, is an area of southwest Turkey encompassing the provinces of Antalya and Muğla, and to a lesser extent Aydın, southern İzmir and western Mersin. The combination of a favorable climate, warm sea, mountainous scenery, fine beaches along more than a 1,000 km (620 mi) of shoreline along the Mediterranean and Aegean waters, and abundant natural and archaeological points of interest makes this stretch of Turkey's coastline a popular national and international tourist destination.
