Be amazed by the iridescent light in the most beautiful cave in Croatia.

The small Croatian island of Biševo has about ten caves, with the Blue Cave standing out as one of the most beautiful caves in Croatia. This unique natural treasure has sun rays passing through an underwater opening, illuminating the cave with gorgeous blue light. The unearthly effect attracts hundreds of tourists each year, and here’s everything you need to know if you want to be one of them.

What is the Blue Cave in Croatia and how was it formed?

Nestled along the rugged coastline of the Croatian island of Biševo, the Blue Cave is a natural wonder that beckons with its ethereal azure glow. The cave’s enchanting luminescence is a result of sunlight penetrating through an underwater opening, reflecting off the limestone floor. 

This optical phenomenon bathes the interior in a mesmerizing blue hue, creating an otherworldly ambiance that captivates visitors. Formed over centuries of geological processes, the Blue Cave stands as a testament to the intricate dance between nature and time.

Blue Cave vs Blue Grotto

When talking about Blue Cave Biševo, oftentimes people say “Blue Grotto Croatia”, but “Blue Grotto” is the name of a famous cave in Italy. To avoid any confusion while looking for information about your trip, make sure to look up “Blue Cave Biševo” or “Modra špilja”, which is its Croatian name.

How to get there

Most people visit it with an organized group — you can book a Blue Cave tour online or in many nearby travel agencies. Take a look at some of the possible departure locations.

  • Komiža, Vis: Most tours depart from there, as the island of Vis is the closest to Biševo.
  • Hvar: To make the most of your day, a lot of offers include stopping by other Biševo sites, like the Green Cave, or combine island-hopping tours.
  • Split: Getting from Split to Biševo and back is a three-hour journey by speedboat. If you’re looking for a Blue Cave tour from Split, definitely choose the one including other sites, too.
  • Camping Village Šimuni and Pag: It’s 180 km away from the cave, so it’s best to go from Pag to Komiža, Hvar or Split, then book a tour from there.

Another option is to visit it by yourself — in that case, you can dock your boat in Mežuporat where the ticket office is located. Due to safety reasons and the preservation of nature, it’s prohibited to enter the cave with private boats.

About the island of Biševo

The tiny island of Biševo is the home of the Blue Cave, one of the greatest sights in all of Dalmatia. Renowned for its tranquility, Biševo offers a stark contrast to its more bustling neighbors. With a population barely touching three dozen, the island exudes a serene charm, inviting visitors to explore its pristine beaches, hidden coves, and vineyard-dappled landscapes.

How to pick a tour of the Blue Cave in Croatia

Choosing the right tour to experience the Blue Cave is a key consideration for any visitor. Various boat tours departing from nearby islands like Vis or Hvar offer the chance to explore this natural wonder. Opt for a tour operator that provides knowledgeable guides, ensuring you not only witness the Blue Cave’s brilliance but also gain insights into the geological marvels of the region. Timing is crucial, as tours are often subject to weather conditions, so checking the forecast and booking in advance will certainly help.

Blue Cave tickets and entry fee

To access the Blue Cave, visitors must secure tickets, usually purchased as part of a guided tour. The entry fee is typically included in the overall tour cost, covering both transportation and the guided experience within the cave. There are several factors to consider before booking a tour: your starting point, time of year and day, the weather forecast, and choosing a comfortable vessel.

Best time to visit the Blue Cave in Croatia

The best time to visit the Blue Cave is during the summer months, from May to September, when the Adriatic Sea is at its calmest. The sunlight penetrates the underwater opening more effectively during these months, intensifying the mesmerizing blue glow within the cave. However, it’s essential to consider the high demand during peak tourist season, and planning a visit during early morning or late afternoon can provide a more intimate experience.

Can you swim in the Blue Cave?

Swimming is not permitted within the Blue Cave itself. However, many tour operators include additional stops at nearby swimming spots, allowing visitors to bask in the Adriatic’s crystal-clear waters.

Best time to visit the Blue Cave

Many agree that the cave is the most beautiful between 11 a.m. and 1 p.m. on a sunny day. Keep in mind that if you come before 10 a.m., you’ll witness its radiance in a much calmer setting. You’ll have to wait in line during high season, but there are cafes and snack shops to keep you busy. To avoid crowds altogether, try visiting it any time from late September to early June.

Inside the cave

Once you enter the cave, you’ll be inside for about 15 minutes enough to absorb the beauty of the blue light piercing through the crystal clear water. Keep in mind that you can’t swim in the Blue Cave (but you can dip your toes in other Biševo caves).

Some like to explore sea depths, while others are prone to conquering the heights. If you’re in the second group, we’re happy to tell you that Croatia has many hiking trails perfect for an active holiday.
