Abstract: The Adana Basin is located between the Taurid Mountains to the north, the Mediterranean Sea to thesouth, the Ecemiş Fault to the west, and the Amanos Mountains to the east. The basin is an important geologicallaboratory with remarkable tectonic, stratigraphic, and morphological features, and contains numerous geologicalheritage elements. This study evaluated the geological heritage value and geotourism potential of Kapıkaya Canyon,one of the important geological and geomorphological formations of the Adana Basin. Kapıkaya Canyon is locatedon the Çakıt Stream of the Seyhan River, a major stream in Çukurova. The canyon is 72 kilometres from Adanaprovince and 5 kilometres from the district of Karaisalı. It is located between Yerköprü, a prominent karst featurewithin the study area that provides observable groundwater flow typical of karst systems in Turkey, and KapıkayaVillage in the Karaisalı district. The canyon has an elevation of 200 meters and a length of 7 kilometres. Along thecanyon route, Paleozoic and Mesozoic units, which form the basement of the Adana Basin, as well as Cenozoic units,are exposed. Subparallel faults oriented in a north–south direction are observed along the Çakıt Valley, placing the geological units in tectonic contact. Geostations containing sedimentary rocks, faults, folds, and fossils, importantfor geoscience education, were identified throughout the canyon. The canyon also boasts waterfalls and hydropowerplants. Its biodiversity is notable for its natural flora and fauna, including monumental trees. Castles, bridges,and inns are cultural assets in the canyon`s vicinity. Geotourism potential includes nature observation and hiking,mountaineering, rock climbing, paragliding, canyoning, camping, nature photography, and visiting cultural heritagesites. The canyon still has the status of a "Sensitive Area to be Strictly Protected".
