Pınargözü Cave

Pınargözü Mağarası is a natural cave exhibiting karstic features located within the boundaries of Yenişarbademli district in Isparta province in southwestern Türkiye. The cave is an active structure connected to an underground water system and ranks among the longest caves in Türkiye^【1】. Speleological studies have indicated that by 1995 approximately 16 kilometers of the cave had been surveyed, but the full extent of the cave system has not yet been reached^【2】. Due to its geomorphological structure hydrographic characteristics and location it has been the subject of scientific and geographical research^【3】.

The cave is situated approximately 8 kilometers from the center of Yenişarbademli district and lies near the Beyşehir Lake basin. It has developed within the karstic structure of the Toros Mountains and is surrounded by mountainous and forested areas. The region is regarded as a holistic ecosystem from a natural landscape perspective. The geological structure has played a decisive role in the formation and development of the cave.

Pınargözü Mağarası is a karstic cave formed within Jurassic–Cretaceous limestone formations^【4】. The cave system features an active underground water flow and is therefore of significant hydrological importance^【5】. A powerful underground water outflow with a discharge rate of approximately 778 liters per second emerges from within the cave^【6】. The river regime varies according to seasonal changes.

The entrance section of the cave has a wide opening and continues with galleries that narrow toward the interior. Along the cave there are galleries siphons and narrow passages of varying heights and widths. The elevation difference between the entrance and the furthest reached point is approximately 720 meters^【7】. Due to its structural complexity the entire cave is not accessible and only certain sections can be studied.

Pınargözü Mağarası has attracted the interest of both local and foreign researchers and has been studied under speleological and hydrological frameworks. It was introduced to the scientific community in 1967 through surface surveys conducted by Temuçin Aygen^【8】. From the 1970s onward studies carried out by various international teams focused on the cave’s length its active water system and its karstic development processes^【9】.

The cave is considered among natural features requiring protection and is managed under controlled use principles due to its environmental sensitivity^【10】. Conservation approaches have been developed to prevent degradation of its natural structure.

Pınargözü Mağarası is one of the well-known natural formations in the region. However due to its physical and hydrological characteristics its tourism potential is limited. Visits must be evaluated within the framework of safety and conservation measures^【11】.

Pınargözü Mağarası is recognized as one of Türkiye’s significant caves due to its length and active water system. It is regarded as a natural formation cited as a reference in speleological literature^【12】.
