Dağlı Kuyluca is one of the deepest caves in Turkey, located within the borders of Kastamonu province, near the village of Dağlı in the Şenpazar district. Discovered in the early 1990s, the cave gained significant attention when it was extensively featured in ATLAS magazine in 1994. Mapped by the Boğaziçi University Cave Research Club (BÜMAK), Dağlı Kuyluca ranks 17th among Turkey’s deepest caves and holds the top position in the Black Sea region. The known depth of the cave is -290 meters, and it still contains many unexplored areas. The cave has become an important site for scientific research and exploration.

Topographical Features
Dağlı Kuyluca is a cave formed in limestone layers, featuring a doline structure that has collapsed due to the effects of water. Studies indicate that the cave’s walls and ceilings were shaped by water-induced collapses. The presence of horizontally oriented galleries within the cave supports this theory. Additionally, a water source originating from within the forest emerges about 50 meters below the cave entrance, flowing into the cave’s depths.
Environmental Features
The surroundings of Dağlı Kuyluca are densely forested, making the cave entrance invisible from a distance. Accessing the cave requires descending rocky terrain. The area also features natural water channels, sinkholes, and unique geological formations known as “witches’ cauldrons,” formed by the erosive effects of water.
Access and Accommodation
Access to Dağlı Kuyluca is via the Kastamonu-Cide highway. After taking the road leading to Hamitli village, a marked trail leads approximately 250 meters on foot, followed by a 25-30 meter descent over rocky terrain to reach the cave entrance. Camping areas are available in the nearby forest, and off-road vehicles can be used to reach these spots. Additionally, various hotels and guesthouses in Cide provide suitable accommodation options.
Important Considerations
Entry to Dağlı Kuyluca requires proper equipment, as the rocky surfaces remain damp and slippery even during summer. Therefore, it is essential to wear appropriate footwear and use the necessary gear before entering the cave. Caution should also be exercised when approaching the rocky areas surrounding the cave, and local guides are recommended for assistance if needed.
Legends
A local legend tells of a mysterious girl known as “Kuyluç Kızı” who is said to reside in the depths of the cave. According to the tale, she lures young men into the cave with her enchanting voice. As a result, young men from nearby villages tend to avoid approaching the cave.
Conservation Status
In 2020, Dağlı Kuyluca was officially designated as a "Natural Asset – Group B Cave" by the Karabük Regional Commission for the Conservation of Natural Assets. This decision was approved by the Ministry in the same year, granting the cave protection as a natural heritage site.
