Blue Cave (Biševo)
Splitsko-dalmatinska županija
The Blue Cave, located on the eastern side of Biševo Island in Croatia, is a remarkable natural sea cave known for its spectacular blue illumination. This effect occurs when sunlight penetrates through an underwater opening on the southern side of the cave, reflecting off the white seabed and bathing the interior in a vibrant blue light, while objects in the water appear silver. The cave has two openings: a smaller, artificially deepened entrance allowing small rowing boats to enter, and a larger vaulted underwater opening responsible for the unique lighting. The cave is relatively shallow, ranging from 3 to 20 meters in depth, making it accessible and suitable for divers of all skill levels. Geomorphologically, it represents a classic karst formation, adding to its scientific and natural significance. Since its public opening in 1884, the Blue Cave has become a major tourist attraction, contributing significantly to the island's appeal. The surrounding island of Biševo offers additional attractions, including other caves, pristine beaches, and a visitor center that highlights the island's rich natural and cultural heritage.
