Blue Cave Hvar: out to Biševo

The day begins at the Kabina Boats office on the harbour, next to Hotel Adriana. From there the boat crosses towards Vis. The listing names the stops that follow: the Green Cave on the islet of Ravnik, Stiniva beach, the Blue Cave on Biševo, then Budikovac island and its Blue Lagoon or the small beach of Pritišćina, and lunch on the Pakleni Islands, the south shore of Hvar or in Vis town.

At the cave your boat stops outside, because the cave can only be visited with the concession holder, in its own small boats. You buy a ticket, transfer, and glide in through an entrance just 1.5 m high. The visit from Mezoporat cove takes about 40 minutes. Then it is back to the speedboat, and on to the coves for the swimming part of the day.

The official Biševo site explains that the effect is strongest in the morning, when the sun shines from the east onto the sandy bottom through the submerged entrance. The Komiža Tourist Board puts the best time for a visit between 10 am and 2 pm, depending on the time of year. On a speedboat from Hvar your timing depends on the crew and the queue, so think of the colour as a gift on the day.

The cave is small. The Komiža Tourist Board gives it as 10 to 12 m wide and 24 m long. It is also alive: a survey in 2019 found 119 marine species inside, five of them strictly protected. Painter Eugen Ransonnet introduced it to the world in 1884, and the official site says that moment marked the beginning of tourism in Dalmatia.

Swimming is the other recurring theme. The boat carries snorkeling gear and safety equipment, and the route is built around coves where you can get in the water. Stiniva, a pebble bay walled in by high limestone cliffs, is a favourite. The Budikovac lagoon gives a calmer, shallower swim later in the day. Expect to spend as much of the day in the sea as on the boat.

Reviewers are honest about the flip side too. Caves can be closed or have long queues, and some days the order of stops changes to work around them. The listing itself warns that severe weather can change the itinerary or lead to a rescheduled or cancelled tour. A good crew turns that into a different day rather than a lost one, and that flexibility is a big part of what people praise.

The weather in Hvar town follows the classic Adriatic pattern. July and August are the hottest months, with average highs of 30.6 °C and 30.8 °C and only about 2 wet days each. May and October are milder, with highs of 23.2 °C and 22.3 °C. The sea warms through the summer, and the long days give the crews plenty of light for a full loop around Vis.

If you can choose, the edges of high season are attractive. In June the sun is up for 15.4 hours at mid-month, and Hvar town's afternoons average 27.6 °C. Early June and most of September also fall in the off-season fare for the cave. Whatever the month, book with free cancellation and keep an eye on the wind the day before.

When that happens, the day goes on without it. Crews swap the cave for other coves and caves around Vis, and the Green Cave, Stiniva and the lagoon still make a fine day at sea. Because the cave ticket is paid on site, you do not pay for a cave you could not enter. One Hvar listing says exactly this: guests are not charged in advance because the closure is out of the operator's hands.

In really rough weather the whole trip may not go. The listing this site recommends says that in severe weather the tour may be rescheduled or cancelled. Plan a spare day if the cave matters to you, check the forecast the evening before, and use the free cancellation if the wind looks wrong. The cave will still be there next time the sea is calm.

Know what the price covers before you go. Included are the boat, the crew and guide, an experienced skipper, bottled water and beer from an icebox, snorkeling gear, and safety equipment with insurance. Not included are lunch and the entry tickets for the Blue Cave and the Green Cave. Budget for those on top of the starting fare of $137.

The listing also states who the day is not for. It is not suitable for children under 2, pregnant women or wheelchair users. A long day on a fast open boat is physical, with bumps on the crossing and swims from the boat, so be honest about your own comfort at sea. If in doubt, put the question to the operator in advance, not at the quay.

Remember that you share a small boat with other visitors. Take your pictures quickly and then put the phone away to look properly, because the visit is brief and the light is the point. Biševo's cave is protected, and its rules forbid swimming or diving inside, so there are no underwater shots to be had here.

The rest of the day is easier. Stiniva photographs best from the water, looking back through the gap in the cliffs. The Green Cave has its own spotlight, a circular opening in the roof that lights the sea to the bottom. Keep your phone in a dry bag between stops; salt spray on a speedboat gets everywhere.

Money matters on this trip. The cave entrances are paid on site, in cash or by card, and lunch is at your own expense. Other listings ask for cash only at the caves, so carry enough cash for the whole group as a backup. A small waterproof pouch keeps notes and phone dry when you swim ashore.

Think about comfort too. Water shoes help on pebble beaches, a dry layer is welcome on the ride home, and a seasickness tablet before you leave is wise if you feel boat motion. The boat provides water and beer, but bring a snack if you get hungry before lunch. Leave anything valuable you do not need at your accommodation in Hvar.

Stiniva is the cove you have seen in photographs. It is a pebble bay on Vis, protected since 1967, formed when a karst cave collapsed during the Ice Age. High limestone cliffs surround it, and you reach it by sea or on steep paths. It is a place to swim, float and look up at the walls.

The Blue Lagoon at Budikovac is the gentle end to the swimming. The boat this site recommends uses it or the small beach of Pritišćina, depending on the day. All of these places lie within the Vis Archipelago Geopark, which covers 6,661 km² of sea and islands. It is a remarkable amount of nature to see in one day from Hvar.

Hvar town is also a good base for the rest of your stay. Daily water taxis run from town to the Pakleni islands, which offer beaches, sailing and kayaking. Inland, the Stari Grad Plain, a UNESCO World Heritage Site, still follows the land division of the Greek colonists who arrived in 384 BC. A Blue Cave day fits neatly into a few days on the island.

If you have not arrived yet, our page on getting to Hvar explains the catamarans from Split, the car ferry to Stari Grad and the crossing from Drvenik. Staying in Hvar town keeps your morning simple: you can walk to the boat office instead of catching an early ferry. That is the main reason we recommend starting the Blue Cave day here rather than from the mainland.

It suits less well if you hate small spaces or rough water. The cave entrance is only 1.5 m high, and the crossing to Vis is open sea. The listing rules out children under 2, pregnant women and wheelchair users. And remember that swimming in the Blue Cave itself is forbidden, whatever you may have seen online.

Finally, keep your expectations about the cave in proportion. It is a small chamber and your minutes inside are short. What makes the day memorable is the whole loop: the light on Biševo, the Green Cave's spotlight, the cliffs of Stiniva and the clear water at the lagoon. Booked with free cancellation and a flexible attitude, it is a superb day out from Hvar.
