The Blue Cave is the pearl of the Adriatic Sea and the most attractive sight of the island of Vis, which attracts a large number of curious tourists.
It can be visited only with a small boat with just a few people on board. The cave has two openings, one of which has no impact on the lighting in the cave and the other one, that lets the sunlight in, is on the south side of the cave beneath the sea.
Rays of sun penetrate through the underwater opening, reflect on the bottom and illuminate the cave with it’s famous blue colour. The best time to visit the cave is in the morning, when the cave’s colours are most intense.
Swimming is not allowed in the cave because of the large number of visitors.
