Fakıllı Cave is situated near the center of Akçakoca district. The cave contains stalactites, stalagmites and columns formed by dripstone. Its internal structure is characterized by natural humidity levels and temperature balance.
Over time, rainwater dissolved limestone bedrock, expanding voids and forming the cave system. This process played a decisive role in the development of Fakıllı Cave’s natural galleries and dripstone formations.
Fakıllı Cave has been officially registered by the Ministry of Environment, Urbanization and Climate Change as a Category B natural cave. This registration aims to preserve the cave’s natural structure and ensure its sustainable use.
