This radiant glow reveals pillars and stalactites formed over millions of years, as well as an abundance of fish, unbothered by the change in lighting. Take a day trip from Hvar to the Blue Cave to be awed by its unique charm and mystical views.

Here's all you need to know about the Blue Cave, one of the most beautiful destinations for day tours from Hvar.

Where is the Blue Cave located?

The Blue Cave is located on the island of Biševo and forms part of the Vis archipelago. It is just 5 kilometers from the island of Vis itself and can be accessed from Hvar or Split easily.

As the natural wonder is only accessible by boat, you'll find the best way to take a tour to the Blue Cave is to book a guided excursion.

These begin around 10:30 AM and last between 6 and 8 hours. Your crew takes care of the route and you'll visit several other locations, in addition to the Blue Cave.

Alternatively, you can charter a boat independently from Split, Hvar or Vis to take a tour of the Blue Cave. This will usually cost more, however, you will have total control over your destinations.

What are the best things to do in the Blue Cave?

Blue Cave is a stunning natural phenomenon located in Croatia with a history that stretches back several centuries. Originating as an underground sea cave, Blue Cave has long been a popular destination for sightseers and adventure seekers alike.

Until the 19th century, the cave was only accessible by diving. However, Baron Eugen von Ransonet — the first man to make mention of the Blue Cave — ordered a small entrance to be created using dynamite.

On clear days, the sun's reflection on the still water of the entrance to the cave casts an ethereal light on its walls and creates a blueish hue that gives the cave its name.

However, you shouldn't be put off by the possibility of a cloudy day, as the blue light still emanates most spectacularly from within the cave, even in poor conditions.

While the waters look incredibly inviting, swimming and other water-based activities are prohibited within the cave. However, if you look hard, you may see the abundance of fish that live under the surface, illuminated by the cave's otherworldly glow.
