Marmaris is an important natural harbour and, thanks to its position at the point at which the Mediterranean and Aegean Seas meet, a leading tourist destination. The Gulf of Gökova lies to its north, the Mediterranean to its south, the Datca peninsula to its west and Lake Koycegiz to its east.
Boasting two large marinas and a number of smaller ones, Marmaris is a major sailing resort that enjoys great popularity in winter. A ferry service provides transport to the Greek island of Rhodes.
Situated in the heart of the city, the Marmaris Netsel Marina has space for 720 boats. It also has water, electricity, telephones, internet, a parking area, a medical service, a restaurant, a taxi service and vehicle hire. The closest airport is that of Dalaman, some 90 km from the marina.
