This is a list of some of the approximately 40,000 caves in Turkey, which provide an important tourist attraction for the country. There are such a high number due to karstification in the west and central Taurus Mountains. The Cavern Research Society (MAD) established in 1964 initially monitored and investigates these caves, a role which has been taken up by BÜMAK (Boğaziçi University Speleological Society) and Karst and Cavern Exploration Unit (under the MTA Geology Studies Department).
