The Blue Cave is one of the most popular tourist attractions in Croatia's Dalmatian islands. It's located on the eastern side of the tiny island of Biševo which is about 3 miles (5 km) southwest of Komiža, a town on the neighboring island of Vis.
The Blue Cave is tucked into a small bay and so-named for the blue light that fills the limestone cave at midday. This natural phenomenon attracts a large number of visitors who travel to the cave from the nearby islands of Vis and Hvar, or from the city of Split on the mainland.
The only way to reach the Blue Cave is by boat. Most visitors make the trip via one of the many organized day tours departing from Split, Vis or Hvar, which often include other stops at tourist attractions on the way. But once on the island of Biševo, there's only one company operating the boats that are authorized to enter the Blue Cave from the small port of Mezuporat. These are boats small enough to pass through the narrow entrance to the cave. For this reason, it's not possible to enter it with any other boat. During the busy summer season, the total time spent inside the cave is five minutes. Note that swimming to or in the Blue Cave is not allowed.
Entry is organized via a system of numbered entry tickets. During the busy summer season, there can be a wait of at least an hour to get inside the cave. There are a few facilities at the port where passengers wait their turn to board, including toilets, a cafe, and a snack bar.

There's also a passenger ferry service operated by Državna Brodska Linija from Komiža to Mezuporat on Biševo. This runs once a day and twice on Fridays from June to September, and four times a week during the offseason. This option is less convenient because of the limited schedule.
