Ölüdeniz (literally Dead Sea, due to its calm waters even during storms; official translation name Blue Lagoon) is a small neighbourhood and beach resort in the Fethiye district of Muğla Province, on the Turquoise Coast of southwestern Turkey, at the conjunction point of the Aegean and Mediterranean sea. It is located 14 km (9 mi) to the south of Fethiye, near Mount Babadağ. It has a sandy bay at the mouth of Ölüdeniz, on a blue lagoon. The beach itself is a pebble beach. The lagoon is a national nature reserve and construction is strictly prohibited. The seawater of Ölüdeniz is famous for its shades of turquoise and aquamarine, while its beach is an official Blue Flag beach. 

Ölüdeniz is also famous for its paragliding opportunities. It is regarded as one of the best places in the world to paraglide due to its unique panoramic views, stable weather conditions, and Mount Babadağ's exceptional height. Babadag (Father Mountain) towering above Ölüdeniz on the Southwest coast of Turkey is a geological marvel that just happens to make for incredible thermals and ideal conditions for paragliding flight. Oludeniz is reputedly the best site in Europe, if not the world, to fly paragliders cross-country in both solo and tandem modes.
