Traveling to Croatia sometime soon? Hey! Add mystical Blue Cave Tour to your Croatia itinerary because if you don’t, you gonna regret it later. Read on to know everything about the Blue Cave in Croatia.
What Exactly the Blue Cave in Croatia is?
The Blue Cave or Blue Grotto or Modra špilja is a splendorous and unique geomorphological natural wonder on the Croatian Adriatic located in a bay of Balun on the island of Biševo, about 9 km (5 miles) from Komiža, Vis, and over 69 km (111 miles) from Split.
A hypnotizing silver-blue light illuminates the space inside the cave when the sunlight hits the surface of the ocean through a crack or vault (natural opening) on its arched roof and reflects off the seabed.
The intensity of the blue color varies with season and time of the day. It’s best visited on a bright sunny day between 11 am and 12 pm as that’s when the sun is just at the right angle intensifying the entire experience.
A Little Bit History of Blue Cave, Croatia
How’s the Blue Cave formed?
Over a period of time, the ocean waves eroded the limestone rock to form the Blue Cave. The cave is pretty tiny (24 m long, about 10 to 12 m deep, and around 15 m high) with a narrow entrance (1.5 m high and 2.5 m wide).
Accessible only by diving through the natural opening (vault on the ceiling of the cave) until 1884 before it was discovered by Baron Eugen von Ransonet, the cave can now be visited on a small boat through a narrow artificial opening blasted out with dynamite.
About Biševo Island
Biševo Island, right in the center of the Dalmatian archipelago is only a few square miles in size. It’s composed of limestone rock and is the remotest and least populated inhabited Croatian Island with just about 15 residents.
There are no accommodation options on the island, hence the travelers only disembark here for a short while.
Porat (Biševska Luka) and Salbunara bays on the island of Biševo have gorgeous sandy beaches if you want to swim and get tanned. But make sure you carry your beachwear.
The other attractions on the island are the Benedictine monastery ruins and the 11th-century well-preserved church of Saint Sylvester or Sveti Silvestar.
Medvidina spilja or Monk Seal Cave is another cave on Biševo Island in the Tresjavac bay.
How to Get to Blue Cave?
The Blue Cave can be easily visited on an organized tour from Split, Trogir, Vis, Hvar, Omis, Makarska, or other neighboring islands.
The Blue Cave Tours from Split or Trogir normally include a visit to other Croatian islands like Hvar, Budikovac, Paklinski, Vis and their attractions. There’s a genuine reason for it.
Bisevo is the remotest island on the Croatian Adriatic Coast and takes about 3 to 4 hours from Split or Trogir by speedboat. It’s way too far to go and way too much money to shell out (more than 100 Euros per person) just to spend 10 to 15 minutes inside the cave. Isn’t it?
Wouldn’t you want a good value for money? So, that’s what tour operators do. They add-on beautiful stopovers in the itinerary to give you a good return for your Euros.
It usually takes around 1 hour 30 minutes from Split or Trogir, an hour from Hvar, and 20 minutes from Komiža on Vis island to get to the Blue Cave.
We spent two beautiful lazy days on Vis island. This made it easy for us to visit the Blue Cave from Komiža.
Our Airbnb host called a local tour operator and arranged a speedboat tour to the Blue Cave.
Sailing to the Blue Cave
The journey to the Blue Cave itself is unforgettable.
Imagine this. A speedboat sailing through the ocean, wind in your hair, bluish blue as far as your eyes could see, the sound of ocean waves filling your senses, the touch of ocean waves healing you, and the taste of adventure spicing up your appetite.
The sailing is smooth more or less with rough phases in-between.
The channel between Biševo and Vis is known to be the most dangerous crossings as the west winds make the ocean recklessly rough.
Thus, the tours operate only when the sea is calm and safe to sail.
The Blue Cave Entrance
Biševo island has 3 ferry ports – Porat, Mežuporat, and Salbunara.
The tour vessels anchor at Mežuporat.
You need to disembark at Mežuporat and board the little official boats (rubber raft) run by a company called Nautički centar Komiža.
No one else is allowed to take their boats inside the Blue cave. A maximum of 3 boats can enter inside the cave at a time. The remaining boats wait outside the cave for the ones inside to come out.
They manage and run the official tours that last for just 5-15 minutes.
The Blue Cave Entry Ticket
More often than not, a tour guide will buy you the ticket upon arrival on the island (included in the tour price).
The Blue Cave ticket costs about 100 kuna (13.5 Euros) during July and August and around 70 kuna (9.5 Euros) for the rest of the year.
You might have to wait in a queue during the peak summer season. Don’t forget to carry sunglasses, hat, sunscreen, and a scarf as the sun is harsh.
The number system makes things easier though.
There’s a ticket counter board that shows the next 12 ticket numbers in an order they need to board the boat to the Blue cave. The official boat holds 12 people at a time.
Also, a staff standing near the waiting area guides everyone.
There’s an option to pay more price to get a fast-track ticket that allows you to skip-the-line.
It was a clear sunny day in June but luckily, we didn’t have to wait at all and could immediately board the official Blue Cave boat. By the time, we came back like after 15 minutes, the queue started building up so yes It can get crowded in the peak months of June, July, and August.
The cave attracts more than 100,000 tourists every summer and sometimes, during peak seasons visitors wait in a queue for 2 to 3 hours to spend just 5 minutes inside the cave.
Mežuporat has a café and decent washroom facilities. You can enjoy a coffee while you wait for your turn. In fact, you must try the local wine – Biševo Plavac when on Biševo.
Can you Swim Inside the Blue Cave in Croatia?
No. Be aware that swimming isn’t permitted in the cave.
As I said, you can satisfy your desire to swim at the sandy beaches of Porat and Salbunara on Biševo island.
You can also swim inside the Monk Seal Cave on Bisevo Island and Green Cave on Ravnik Island.
