Quick answer
Entry to Modra špilja costs 24 EUR per person at the high-season rate, and that figure already includes the mandatory boat transfer from the Balun Bay mooring into the cave. The site operates 09:00–17:00 every day of the week. Swell or strong wind can close the entrance without notice, so the fee is best treated as conditional on the sea.
The cave has no land entrance. Its only opening is a low arch about 1.5 metres high at the waterline, which means every visitor to Modra špilja finishes the journey lying back in a small wooden boat while an oarsman times the swell. That physical constraint explains almost everything else about the place, including how the blue cave ticket price is constructed: the transfer is not an optional extra but the only possible way in, so it sits inside the fee rather than beside it. Most travellers arriving from the mainland do not buy the cave fee in isolation. They book a Dubrovnik Blue Cave tour or a Split-based island run, and the cave charge is one line inside a longer day that usually threads Biševo together with Stiniva cove, the Green Cave on Ravnik, and a swimming stop off Budikovac. The operator collects the site fee on the reader's behalf at Balun Bay, hands the group to the local shuttle boats, and waits offshore. Reading a blue cave ticket price against a tour price therefore compares two different things — one is an entry charge to a protected natural monument inside the Vis Archipelago Geopark, the other is a full day of skippered sailing from the mainland. The light is the variable no fee controls. Sunlight enters through a submerged side opening, refracts through the water, and throws the silver-blue glow across the limestone walls only when the sun sits at the right angle — which is why the recommended arrival window is 11:00–13:00. Outside it, the chamber still impresses, but the colour drains toward grey. Wind matters as much as hour: when the jugo blows or the swell lifts, the arch becomes impassable and boats are turned back at the mooring, sometimes after the crossing from Komiža. The practical conclusion is to build the day around the light window and the sea forecast, then treat every other decision as secondary. Check the day's conditions before committing to a crossing, confirm with the operator whether the site fee is collected in advance or on arrival, and keep the return leg loose. Readers comparing sailings, departure ports and included stops will find those laid out on the booking pages for each route.

Essential Preparation Before Paying Your Blue Cave Ticket Price
A Blue Cave visit depends on sea conditions and timing, so a few decisions made in advance decide whether you get inside at all.
-
Reserve your Biševo trip early — Summer departures from Split, Hvar and Komiža fill weeks ahead, and daily entry to the cave is capped.
-
Check the marine forecast beforehand — Swell or strong wind at Balun Bay closes the low entrance and cancels sailings without notice.
-
Confirm your operator's cancellation terms — Weather closures are common, so know whether you are refunded or rebooked before you pay.
-
Target the 11:00–13:00 arrival window — This is when sunlight hits the underwater opening at the angle that produces the blue glow.
-
Carry photo ID and cash — Some transfers and island services still check names and take cash only.
-
Call +38521713644 on the morning — Staff confirm whether the cave is open before you commit to the boat ride.
-
Wear grip-soled shoes, skip loose bags — You transfer into a small tender and step onto wet stone at the cave mouth.
-
Leave the return schedule flexible — Delays at the cave entrance are routine when boat queues build up.
