About this site
The Blue Cave sits on the small island of Bisevo, off the southern coast of Vis in the Croatian Adriatic. It is best known as a sea cave where sunlight entering through an underwater opening produces a strong blue glow across the water and cavern walls, drawing visitors by boat from Vis and Komiza. As a dive site, it is rated a beginner level dive.
