What to do at the Blue Cave?

1/4

Boat Ride into the Cave

Hop on a small wooden boat operated by licensed guides. The narrow entrance requires visitors to duck as the skipper navigates inside, creating a sense of anticipation before the glow reveals itself.

Experience the Glow

Once inside, you’ll witness the surreal blue light that makes the cave world-famous. The water glows beneath you, and the walls shimmer—an unforgettable natural spectacle lasting around 10–15 minutes.

Combine with Island Hopping

Most tours combine the Blue Cave with stops at Vis, Hvar, Budikovac (Blue Lagoon), or the Pakleni Islands, giving you a full day of swimming, snorkeling, and exploring.

Photography

The ethereal light creates one of the most photogenic spots in Croatia. Wide-angle and low-light settings capture the glow best, but simply soaking in the view is just as memorable.

Loved the experience, great vibes, great DJ, great weather, awesome promoters. Lucky, the promoter took care of me (as a solo female traveler, sometimes you need an extrovert to hype you up and include you) ! Owner was also there to oversee everything and make sure that everyone is having a good time!

Many thanks for a wonderful day! Despite the guide's absence, the boat's driver calmly and professionally handled both navigation and explanations. His constant attention to the wind and the sometimes turbulent conditions made the tour all the more impressive. An unforgettable experience, combining scenic beauty and boat handling. Well done to him

Loved the variety of stops and the swimming opportunities. The small group (11 of us) was the perfect size. Communication with the tour guide prior to the trip was good. Would highly recommend this great day out

The music was perfect and the weather joined us! Marco and the sailor were really kind and friendly and the food was really good with the free white wine! The restaurant was perfect! I RECOMEND IT A LOT!

Everything was fine. Only the email from Headout stated a starting location, which was not correct. And it was also written that you had to be there by 7.00am. It was not clear to me that the departure point had been changed and that the time for the meeting point had also been changed to 7.15 am. This made the start very hectic for me! Best regards

History of the Blue Cave in a Nutshell

The Blue Cave was first described in the 19th century by Baron Eugen von Ransonnet, an Austrian explorer who introduced it to the wider world. Originally accessible only to skilled divers, the cave was later widened to allow small boats. Today, it’s a protected natural monument, carefully regulated to balance visitor access with conservation. Its fame grew as artists, poets, and travelers spread word of its unearthly beauty, making it one of Croatia’s most visited natural attractions.

Conservation & Responsible Tourism

The Blue Cave is a fragile ecosystem. Swimming inside is prohibited to protect the water clarity and prevent damage. Visitors are asked to follow skipper instructions, avoid littering, and book with certified operators that comply with local sustainability practices. By respecting these rules, you help preserve the cave for future generations.

Helpful tips for visiting the Blue Cave

Book in advance: Tours sell out quickly in peak season (June–August), especially morning slots when the light is best.
Go early: Aim for morning departures (10 am–12 pm) when sunlight creates the most vivid blue glow inside the cave.
Bring cash: The cave entry fee (€12–€14) is often collected on-site and may not accept cards.
Pack essentials: Sunscreen, hat, water shoes, swimwear, and a towel. The rocky beaches and sharp stones can be tough barefoot.
Check the weather: Cave access depends on calm seas. Rough waters or high winds can cancel or delay entry.
Choose the right tour: Full-day 5-island tours include more highlights; half-day trips are quicker but cover fewer stops.
Mind the queues: Expect a wait during peak hours as boats queue to enter the cave. Patience is key.
Stay hydrated: Bring water, especially in summer when it gets hot on the boat.
Capture the moment: Cameras struggle inside the cave; phones often do better for the glowing blue effect.

A half-day tour is typically ideal, especially if you want to enjoy other nearby spots like Stiniva Cove.

What are the facilities and amenities available at the Blue Cave?

The Blue Cave is located on a small island, so facilities are limited. There are no restrooms or dining options at the cave itself. However, on the nearby island of Vis, you’ll find restaurants, cafes, and restrooms. Be sure to carry essentials like water and snacks, especially if you’re taking a longer tour.

What makes the Blue Cave on Bisevo so unique?

This natural phenomenon creates an otherworldly glow that visitors come from all over the world to witness. The best time to see this effect is around midday when the light is at its strongest.

What should I wear when visiting the Blue Cave?

Comfortable, light clothing and swimwear are recommended, as many tours also stop at beaches. Don’t forget sunscreen, sunglasses, and a hat, as you’ll be on the water for several hours. A light jacket might be useful as it can get chilly on the boat.

Is the Blue Cave accessible for people with mobility challenges?

Unfortunately, the Blue Cave is not very accessible to those with mobility issues. The boats used are typically small, and the entrance to the cave is low, requiring passengers to duck down as they enter.
