The Blue Cave (Modra špilja) lies off tiny Biševo Island, west of Vis in Croatia’s central Adriatic. You can day-trip there from several Dalmatian hubs, with most organized tours departing by speedboat from Split, Hvar, or Trogir, plus easy connections from Vis itself.
Split → Blue Cave (Biševo)
- ~65–70 km by speedboat via Vis and Pakleni
- Full-day 5-islands itineraries, often 10–11 hours total
- Typical stops: Blue Cave, Komiža, Stiniva, Blue Lagoon, Hvar
- Good if you want a “greatest hits” Dalmatian boat day
Why it works: Split is the main regional hub, so you get the widest choice of Blue Cave day tours and departure times, letting you fold a big island-hopping adventure into an otherwise land-based Split stay without changing hotels.
Hvar → Blue Cave (Biševo)
- Around 35–40 nautical miles by fast boat
- Usually 7–8 hours round-trip from Hvar Town
- Often combines Blue, Green, Monk Seal caves plus swim stops
- Shorter crossings, slightly later morning departures
Why it works: Starting closer to Biševo means less time in open sea and more time at caves and coves, making Hvar a strong base if you want an unhurried day with extra swimming rather than the longest possible itinerary.
Trogir → Blue Cave (Biševo)
- Adds ~30 minutes transfer versus Split departures
- Many tours shuttle to Split harbor, then share boats
- Same 5-islands routes and inclusions as Split tours
- Handy if you’re already staying near Trogir’s marina
Why it works: Using Trogir lets you tap into Split’s huge tour supply without relocating; transfers are handled for you, so you simply board near Trogir, ride into Split, and continue straight out toward Vis and the Blue Cave.
Vis / Komiža → Blue Cave (Biševo)
- Komiža–Biševo about 5.5 km, ~30 minutes by local boat
- DIY cave visits plus flexible time around Vis Island
- Easier to go early or late and avoid longest queues
- Suits slower itineraries with at least one Vis overnight
Why it works: Basing on Vis turns the Blue Cave from a long “there-and-back” dash into a short side-trip within a deeper Vis stay, ideal if you’d rather explore local beaches, villages, and history at your own pace between cave visits.
