Turkey's longest cave features hurricane-force winds and a labyrinth of treacherous, flooded passages
In short: Hidden within the Taurus Mountains, Pınargözü Cave is a subterranean enigma. Known as the eye of the water, it remains largely unmapped due to its extreme environment. Explorers must navigate frigid waterfalls and submerged galleries, all while battling intense winds that can reach speeds equivalent to a hurricane.
Located in the Kızıldağ National Park on the side of Mount Dedegöl, Pınargözü Cave is widely regarded as the longest in Turkey, though its true length remains a subject of debate. The cave is a classic example of karst topography, carved into Triassic limestone that is highly prone to erosion. This geological structure has created a complex, largely horizontal system filled with vertical chimneys, cascades, and subterranean rivers. The cave acts as a massive outflow, with the Devre Su stream constantly pouring from its narrow, half-metre-wide entrance.
The cave's environment is notoriously hostile. A powerful chimney effect, caused by temperature variations between different altitudes, forces air through the opening at speeds up to 166 km/h. Inside, the temperature remains a steady 5 °C, while the water flowing through the system stays between 4 and 5 °C. These conditions, combined with flooded sumps and massive waterfalls, make exploration possible only during the summer months and exclusively for professionals equipped with specialized gear. Even then, the cave remains closed to the general public.
Since its initial discovery in 1964 by Temuçin Aygen, the cave has been the site of numerous international expeditions. Progress has been incremental and dangerous; early teams were frequently halted by sumps and waterfalls. By 1971, surveyors had documented over 4,600 metres of passages. Later efforts, including those by the French Federation of Speleology in the late 1980s, pushed the known boundaries significantly further. While some estimates suggest the cave could exceed 16 kilometres in length, local project managers have challenged these figures, noting that the full extent of this subterranean network remains unmapped and mysterious.
