Beneath the Mediterranean’s azure kiss, the Blue Cave in Croatia cradles secrets in its blue heart, where the sea whispers in sapphire hues and time dances to the rhythm of the deep.

The Blue Cave’s beauty has been jealously guarded by nature, which was nearly impossible for mankind to visit. In 1884, the undersea entrance was expanded at the request of Baron Ransonet. Barely enough to allow a tiny boat to pass through, allowing bigger parties of people to explore the cave.

The Blue Cave is still unmatched in its stunning blue beauty. Despite being a popular tourist attraction in Croatia.

Every year, thousands of tourists are attracted to the uncanny impact of Blue Cave.

The history of the cave and how it was formed

Although the precise date of the Blue Cave’s discovery is unknown, it is known that local fishermen were aware of it for many generations prior to it spreading to the rest of the world. After discovering it during a diving trip, Austrian explorer, artist, and speleologist Baron Eugene von Ransonet-Villez first described and displayed it to the public in 1884.

Following his advice, dynamite was used to blast a 5 m high by 2.5 m wide artificial entry into the rock to allow boats to pass through. The opening is big enough for rowboats and dinghies, but not so big that it obstructs the interior lighting.

Biševo island

Slightly larger than 5.8 km2, Biševo is located about 4 km from Vis Island. Only a few people live on it. The island is well known for its Blue Cave, but there are a lot more sea caves, stunning sand and pebble beaches, and cliffs. And other breathtaking natural gems that are hidden away. This is a much lesser-known about Biševo island.

Biševo, despite its modest surface area, is a very exciting place to sail and boat in general. Because of its location far out in the open Adriatic. Its coasts exhibit a particularly powerful influence of the sea and are a true witness to its relentlessness. Due to these factors, the sea’s and salt’s effects have caused nature to build a veritable little museum of erosion creations.

Can you swim in Blue Cave?

Unfortunately, swimming is not permitted in the Blue Cave. And it simply would not be safe given the constant stream of visitors arriving and departing by boat. While waiting for your turn, you can swim close to the ticket office. Additionally, the majority of Blue Cave trips involve swimming at some stunning beaches, so if you’re determined to get wet, you can.

Why is the Blue Cave blue?

Sunshine that enters the cave through the roof and lights the water is what gives the Blue Cave in Croatia its blue color. The cave then glows blue as a result of this reflecting all around it. Similar blue caves can also be found in Croatia, however far fewer people visit them.

Depending on the season, you may have to wait anywhere from 10 minutes (if you’re fortunate enough to be among the first) to two or three hours to enter the Blue Cave in Croatia. Of course, there will be a longer wait during the busiest time of year.

How do I get to the Blue Cave?

Tours are the most convenient way to visit the Blue Cave in Croatia. They leave from Split, Hvar, Brač, Vis, and even Dubrovnik.

To reserve a spot, you can buy a ticket here.

Can I go to the Blue Cave without a tour?

It is totally feasible to visit the Blue Cave alone. But it also involves careful planning and can be a very difficult journey. Consider the possibility that, in the absence of a tour guide, you may overlook interesting locations that are only known to seasoned residents.

When is the best time to visit the Blue Cave?

The Blue Cave in Croatia is best visited on a sunny day since light from the sun only causes the cave to sparkle through its crack. If at all possible, go during the off-season to avoid the worst of the crowds. Try to go there as early as possible in the morning.
