Tourism While the region has a long coastline, international tourism is not at the level of the neighbouring Antalya Province. There are a small number of hotels between Erdemli and Anamur that attracts tourists. Cilicia tourism is mostly cottage tourism serving the Cilicia locals as well as residents of Kayseri, Gaziantep and surrounding areas. Between Silifke and Mersin, high-rise and low-rise cottages line the coast, leaving almost no vacant land. The coastline from Mersin to Karataş is mostly farmland. This area is zoned for resort tourism and is expected to have a rapid development within the next 20 years. Karataş and Yumurtalık coasts are home to cottages with a bird conservatory between the two areas. Arsuz is a seaside resort that is mostly frequented by Antakya and İskenderun residents. Plateaus on the Taurus mountains are cooler escapes for the locals who wants to chill out from hot and humid summers of the lower plains. Gözne and Çamlıyayla (Namrun) in Mersin Province, Tekir, Bürücek and Kızıldağ in Adana Province, Zorkun in Osmaniye Province and Soğukoluk in Hatay Province are the popular high plain resorts of Cilicia which are often crowded in summer. There are a few hotels and camping sites in the Tekir plateau. Balneary
