Two state lines carry passengers out of Dubrovnik on a published tariff. Line 807 reaches all three Elafiti at €3.40 off-season and €5.40 in season, four times a day. Line 9807 reaches Mljet all year and Korčula for two months of it.
A boat trip with a state tariff attached to it
Most of what is sold as a boat trip from Dubrovnik is a commercial excursion, which sits outside the state coastal line register entirely: no published fare, no public service obligation, nothing to check. Running alongside those, on the same water and to the same islands, are scheduled services with a state tariff and a legal obligation to sail.
The comparison is worth making explicitly because the two are rarely put side by side. A scheduled crossing to any of the three Elafiti costs €5.40 one way in season and €3.40 outside it, with a child fare between €1.80 and €2.10 depending on which island. Whatever an excursion is worth, that is the number it is being measured against.

Tariff period
Two of those crossings have no off-season fare, and the reason is the strongest single fact on this page. Line 9807 runs its full route — Ubli, Korčula, Polače, Sobra, Šipanska Luka, Dubrovnik — only between 3 July and 30 August. Outside 29 May to 30 August it serves Sobra, Šipanska Luka and Dubrovnik only. Ubli, Korčula and Polače are not served at all, so there is nothing to price.

Frequency matters more than fare
On a day trip the fare is rarely the binding constraint; the number of rotations is. Line 807 runs four sailings a day Monday to Saturday and two on Sundays and holidays. That asymmetry is the single most useful thing to know about boat trips from this city, because Sunday is when most visitors have a free day.
Four rotations supports two islands comfortably and three in a rush. Two supports one. A Sunday plan built on a weekday timetable is the most common way a day out of Dubrovnik goes wrong, and it goes wrong at the far end, in the afternoon, on a pier.
There is a second frequency point that is easy to miss because it works in your favour. Line 807 keeps its four rotations Monday to Saturday in every month of the year, not just in summer, because it is a state line with a public service obligation and the people it serves live on those islands in February. What changes between seasons is the tariff, which reverts to €3.40 on 28 September, and the last evening sailing. That makes these three islands one of the very few genuinely year-round day trips in Croatia.
| Line | Reaches | Mon–Sat | Sundays and holidays | Season |
|---|---|---|---|---|
| 807 | Koločep, Lopud, Suđurađ | 4 | 2 | All year |
| 9807 | Šipanska Luka, Sobra | 1 to 2 | 1 to 2 | All year on this segment |
| 9807 | Polače, Korčula, Ubli | Full route only | Full route only | 3 July – 30 August |
| 9808 | Sobra, Korčula, Lastovo | State line | State line | Timetable not in the verified bundle |
The last row is there for completeness and carries no numbers, because the per-line timetable for 9808 is not in the verified bundle. Neither is the one for car ferry 831, which runs the same Elafiti port sequence as 807 and takes vehicles. No departure time or fare for either appears on this page for that reason.
Planning the Korčula day trip from Dubrovnik in June
It is the trip everyone wants and for most of the year there is no state boat for it. Line 9807 reaches Korčula only while its full route runs, 3 July to 30 August. Outside that window the fare table has no entry for Dubrovnik to Korčula, because the sailing is not there to price.
What remains is a commercial catamaran on the Split chain, which runs to summer demand and has no obligation to sail, or the road down Pelješac to Orebić and the 20-minute crossing on line 634 — which berths at Dominče, roughly 3 km from Korčula town rather than in its harbour. Both are long days. Mljet, on the same catamaran, is served all year at Sobra and is the better shoulder-season answer.
What none of this covers is the excursion market itself, and deliberately so. No excursion price, departure time or itinerary appears here, because those are not in the register and cannot be sourced. What the register does give you is the floor: a public boat to the same islands at a published fare, running four times a day for eleven months of the year.
Used properly that is a planning instrument rather than a bargain. The scheduled service tells you which islands are genuinely reachable and back in a day, on which days of the week, in which months. The Elafiti come out of that test well in every month; Korčula comes out of it badly in nine of them; and the shape of the southern network is why.
What do you need to work out next?
The scheduled boats set the floor. These come next.
Where to stay
Where should the boat days start from?
The 807 leaves Suđurađ first at 06:00 and returns from Dubrovnik last at 20:00.
Getting around
Which of the three islands takes a day?
All three cost the same fare from the city: €5.40 in season.
When to go
What is still running in October?

Planning
Is Mljet a day trip or a stay?
Sobra is served all year; Polače only from 29 May to 30 August.
