Split's most popular tours sell out daily in summer — the Blue Cave & 5 Islands speedboat tour in particular needs to be booked before you arrive. Diocletian's Palace is free to wander independently, but guided tours add enormous historical context. Here are the tours worth booking in 2026.
✔ Blue Cave & 5 Islands speedboat — sells out every day in summer
✔ Plitvice Lakes day trip — limited spaces, very popular
✔ Trogir & Krka day trip — popular with families
1. Blue Cave & 5 Islands Speedboat Tour
The unmissable Split experience. A speedboat visits: Blue Cave on Biševo island (only illuminated in the morning when sunlight enters through the underwater entrance — go before 11am), Hvar Town (2 hours), the Green Cave on Ravnik, Stiniva Cove on Vis (the most beautiful beach in Croatia) and often Vis Town. More than 5 islands and 2 extraordinary sea caves in a single day.
💡 Book the 8am morning departure — the Blue Cave loses its electric blue illumination after about 11am as the sun's angle changes.
Check Availability →2. Plitvice Lakes National Park Day Trip
Croatia's most visited national park (2 hours north of Split) — 16 terraced turquoise lakes connected by 8km of wooden walkways and dozens of waterfalls. The largest waterfall (Veliki Slap, 78m) is Croatia's highest. A UNESCO World Heritage Site since 1979. The guided day trip includes transport and the option of both upper and lower lake circuits.
💡 Book well ahead in July–August — Plitvice limits daily visitor numbers. Go in May, June or September for the best experience with manageable crowds.
Check Availability →3. Trogir & Krka Waterfalls Day Trip
Two of Dalmatia's finest in one day. Trogir: a tiny UNESCO-listed medieval city on an island connected by bridges — the Cathedral of St Lawrence with its extraordinary 13th-century Romanesque portal and the compact streets of one of Croatia's finest small towns. Krka National Park: the Skradinski Buk waterfall system with swimming in the natural pools below the cascades.
💡 Krka swimming is not always permitted — check before booking if swimming is important to you (restrictions are applied for environmental protection).
Check Availability →4. Diocletian's Palace Historical Tour
A guided walk through Diocletian's Palace with a certified archaeologist or historian — the underground cellars (the best-preserved Roman substructure in the Adriatic), the Peristyle, the Cathedral (originally Diocletian's mausoleum), the Vestibule and the four city gates. The historical context transforms the palace from an impressive ruin into an extraordinary story.
💡 The palace is free to enter independently but the guided tour adds enormous value — particularly for the underground cellars and the Imperial Apartments interpretation.
Check Availability →5. Hvar Island Day Trip
Take the public catamaran to Hvar Town (1 hour, €15 return) or join an organised tour that includes a local guide. Hvar Town — the main square (one of the largest in Dalmatia), the fortress above, the oldest community theatre in Croatia (1612, Hektorović Theatre) and the lavender fields of the interior. A guided tour adds the context of Hvar's extraordinary Venetian, Ottoman and Croatian history.
💡 The catamaran is the best independent option (no tour needed, buy return ticket immediately on arrival). Join a guided tour if you want local expertise on Hvar's history.

FAQs
Is the Blue Cave worth it?
Absolutely — one of the Mediterranean's natural wonders. The electric blue illumination from the underwater sun shaft is genuinely extraordinary. Go in the morning for the best effect.
How much do Split tours cost?
Blue Cave & 5 Islands: €60–80. Plitvice: €55–75. Trogir & Krka: €45–65. Diocletian's Palace walking tour: €20–35. Free walking tours also available from the Riva.
Should I book Plitvice from Split or Zagreb?
Either works. From Split it's a 2-hour drive. From Zagreb it's 2 hours in the other direction. If you're based in Split, the Split day trip operators are equally good.
Can you visit Diocletian's Palace without a tour?
Yes — the palace is free and open 24/7. The underground cellars (€10) are the only paid section. A guided tour adds significant value but is not required.
