Everything You should know about the Blue Cave

What exactly is the Blue Cave?

Blue Cave is an extraordinary geomorphological wonder located in the bay of Balun on Bisevo Island. This island is 5 miles from Komiza and about 111 miles from Split.
This island is in the Adriatic Sea which encloses the waterlogged Blue Cave. The Bisevo Island is from the series of Komiza Trio islands amongst which Vis and Sveti Andrija are the other two.
When the sunlight strikes the ocean, it illumines the interior of the cave with an eerie silver-blue light. This hypnotizing blue aura is cast when the sunlight enters through a narrow crack in the arched roof and mirrors of the limestone seabed.

These limestones reflect the light and generate a prismatic blue glow which causes an aqua halo to be created around the cave. Bisevo Island is a deserted place and only a few fishermen reside here to capture the opportunity to hunt for rare species of fish.

Structure and geography

Bisevo Island is shrouded by limestones and cliffs. As the time elapsed, the ocean waves caused erosion of the limestone rock which triggered the formation of Blue Cave on Bisevo Island. Besides the Blue Cave, Monk Seal Cave, Benedictine monastery ruins, and Saint Sylvester church are also significant markers perched on this island.

The cave is quite minuscule featuring a depth of 10-12m, a height of 15m, and a length of 24m. The entrance is quite narrow featuring a height of 1.5m and a width of 2.5 m.
The cave has distinct widths in different areas and in some zones, the cave begins to shrink narrower in its width.

History

Before it was discovered by Baron Eugen Von Ransonet in 1884, diving through the crevice in the roof of the cave was the only way through which the island could be accessed.
The Austrian explorer Baron not only channeled the unexplored territory around the Blue Cave and blasted an opening in the cave with dynamite thus allowing easy access to all but also spread the word about its discovery.
And since then, Blue Cave became one of the most popular destination spots, enticing 100,000 visitors every summer.

When should you visit the Blue Cave in Croatia?

May and September are deemed to be the best months to visit Blue Cave. At this time the usually turbulent and rough Adriatic Sea is calm and pacified.

Since there are no stringent rules for visiting the magical site of the cave, tourists can visit it on their own at any time of the year.

But if you want to hire the services of travel agencies to visit Blue Cave, then the tours from Split to Bisevo Island are only available between April and November. Apart from these months, traveling in the Adriatic Sea is dangerous because of the storms creating turbulence in the waters.

If you want to travel with other tourists and feel safe traveling with a big group to this remote island, May and September are the ideal months. However, if you can’t stand long queues and heavy crowds, then book a package in April or October.
