In an effort to diversify tourism in Turkey, the Ministry of Culture and Tourism has opened 50 of the nation's over 20,000 caves to visitors. The 'Cave Tourism Project' was initiated in an effort to draw in tourism from the coast to the nation's internal regions to influence development while also protecting natural and cultural values.

From a tourism perspective, Turkey's caves offer a significant potential and it is considered there may be up to 20,000 caves with appropriate rock formations for access. Out of these, 1,500 have been inspected by the General Directorate of Mineral research and Exploration as well as a number of other foundations, clubs, communities and establishments involved with caving. After the research conducted, it has been determined that the Pınarözü cave in Isparta, which spans over 15 kilometers in length, is officially 'Turkey's longest cave' while the Peynirlikönü Cave in Mersin is classified as 'Turkey's deepest cave' with a depth of 1,429 meters.
