Dupnisa Cave

Dupnisa Cave is a show cave in Kırklareli Province, Turkey, consisting of three interconnected sections with distinct features and depths. The upper level holds the Kuru and Kız caves, while the Sulu cave extends approximately 60 meters below, creating a multi-layered underground system.

The cave's geological formation began during the Early Jurassic period roughly 180 million years ago through the erosion of marble deposits. This slow process of water wearing away the rock eventually created the complex underground passages visible today.

The cave's name comes from the Bulgarian word Dupnitsa, reflecting historical Bulgarian settlements that once thrived in the region. This linguistic connection reveals how different cultures shaped the area over time.

The cave closes from November to May each year to protect bats during their breeding season, so plan your visit accordingly. Guided tours are the standard way to explore the system, as this ensures safety and provides useful information about the formations.

The cave shelters roughly 60,000 bats from eleven different species, making it a critical refuge for these mammals in the region. This extraordinary concentration of bat populations is why the cave remains carefully protected year-round.
