The Blue Cave is located in Balun bay on island Bisevo that is approximately 4.5 nautical miles from Komiza town on Vis island. Over 10000 tourists visit the cave every year. It is a water logged sea cave and is one of the most popular natural beauty sights in the Adriatic. Its popularity is due to the glowing blue light that appears when the sun is high on the horizon. The cave was first painted and described by Baron Eugen von Ransonet. Originally you could only access the cave by diving into it as the only natural entrance was below the sea level. In 1884 the artificial entrance was built, it was large enough for small boats to enter. The natural cave entrance is located on the southern side and is said to look like a vault on the ceiling of the cave. The sunlight enters the cave trough this opening and creates an iridescent blue glowing effect in the entire cave. There is also a stone bar that connects the two walls of the cave that is visible just under the waterline. This bar is a favorite for photographers both under the water and above it. Depending on the current season, the best time to visit the cave is between 11 AM and 1 PM when the sun is high above. At this time the sunlight reflects trough the water and the white floor of the cave and shines the cave in a blue light, at the same time the objects in the water appear silver.
The cave was formed by the waves as the seawater eroded the limestone rock that the entire island Bisevo is composed of. The cave is 10-12 meters deep, up to 15 meters high, 24 meters long and 1.5 – 2.5 meters wide.
On the south side of island Vis, in front of the Rukavac cove, there is a small Ravnik island and on its southwest side you will find the Green Cave. Trough the crack in the ceiling you have sunlight penetrating and so creating the green color that reflect in the cave. The color green comes from many green algae that are cover the bottom of the cave. The Green cave has two entrances and is quite spacious so boats can enter it without a problem. It is a beautiful act of nature and swimming is allowed, it is especially interesting to snorkel or dive inside the cave. The cave was formed by the waves that eroded the limestone.
