Dalyan is a town in Muğla Province located between the well-known districts of Marmaris and Fethiye on the south-west coast of Turkey
. The town is an independent municipality, within the administrative district of Ortaca.
Dalyan achieved international fame in 1987 when developers wanted to build a luxury hotel on the nearby İztuzu Beach, a breeding ground for the endangered loggerhead sea turtle species. The incident created major international storm when David Bellamy championed the cause of conservationists such as June Haimoff, Peter Günther, Nergis Yazgan, Lily Venizelos and Keith Corbett.
Above the river's sheer cliffs are the weathered façades of Lycian tombs cut from rock, circa 400 BC. The ruins of the ancient trading city of Kaunos are a short boat trip across the river.
The south of Dalyan on the Mediterranean coast, lies İztuzu Beach, near the village of the same name is a popular area for sunbathing and swimming. There are regular boat and minibus (dolmuş) services to the beach. Visitors should be aware of the wooden stakes in the beach to mark nesting sites. The road route is particularly scenic, offering views of Sülüngür Lake.
