Yumurtalık is a small town and a Mediterranean port at a distance of about 40 kilometers from Adana as well as a district in the Adana Province of Turkey. Its name in English means Egg Nest. Yumurtalık's population does not exceed 5,000 in winter, but in summer, it rises to around 40,000 people since many residents of Adana have holiday homes in Yumurtalık. Yumurtalık has a large free economic zone where the production units of up to thirty companies are presently in operation or being built. Fields of activities include industries ranging from petrochemicals, synthetic fibers and the steel industry. In addition, there are also plans for establishing a major shipyard. The port has a long history dating back to at least 2000BC and Hittite pottery has been unearthed in the 17th century BC mound of Zeytinbeli Höyük. Subsequently, many more civilisations have passed through, as it was ruled by the Anatolian Beylik of Ramadanids and after the 16th century, by the Ottoman Empire. The Kestanbol Castle is located south part of Yumurtalik, the Kestanbol castle is known as Ayas Kalesi. The castle comes from the middle ages and was repaired by the Ottoman Empire. Ayas Kalesi is reported to be the dock used by Marco Polo when sailing back from Asia. The sea is clean and there remains a relaxed feeling to this coast, which makes Yumurtalık a holiday and weekend retreat for the people of Adana and of other cities in the Çukurova region. They come during good weather to stay in seaside holiday flats generally built in compounds. There are also small hotels and guest houses for the occasional visitor who wants to swim during the day and stroll along the beach or into the village in the evenings. The public beaches are not very well kept by the municipality, and have sometimes been covered with litter, but this is changing. The holiday villages have private beaches which are kept clean and these can also be used by outsiders for a small daily entrance fee.
A number of beaches in Yumurtalık are also the nesting places for the loggerhead sea turtle known as the Caretta caretta. The fact that these ladies (turtles) do not arrive in Yumurtalık with credit cards makes them a secondary concern. In fact, the amount of beachfront holiday properties is also part of the problem - even though the sand is clean the turtles will not lay their eggs on these busy beaches with neon-lit discothèques blasting out all night. Adequate protection for the Loggerhead nesting habitat, like established in Dalyan by British conservationist June Haimhoff, continues to remain a critical question. These endangered species lay eggs only in Yumurtalık, on Akyatan Beach in the neighboring Karataş district and on İztuzu Beach in Dalyan in southwestern Turkey. A rather sad commentary when the very name Yumurtalık means, among other things, egg nest in the Turkish language.
As well as tourism, the fertile agricultural land that extend behind the coastline are also a key factor for the local economy and exceptional tomatoes, watermelons and other fruits and vegetables are grown in abundance in Yumurtalık. Just outside Yumurtalık is the Botaş Oil and Natural Gas Terminal. It marks the end of the Kirkuk–Ceyhan Oil Pipeline running from Northern Iraq, which was opened in the 1970s. Refined oil is also imported through here by sea. Immediately to the southwest, there is the terminal for a crude oil pipeline from Baku, opened in 2006. Further in the same direction, there is a recently built coal-fired power plant.
