Blue Lagoon Split: 8 Best Tours Compared 2026

The Blue Lagoon most people mean when they search for it from Split is Krknjaši Bay, a shallow channel of sand-bottomed water between the island of Drvenik Veli and the islets of Krknjaš Veli and Krknjaš Mali. It sits about 14 nautical miles from Split and 8 from Trogir, there is no road to it, and the colour comes from the pale sand a couple of metres below rather than from anything in the water itself.

Every option here is a three-island boat trip built around that bay. The eight compared here cost €70 to €90, run either about five hours or about nine, and all rate between 4.5 and 4.9 across more than 19,000 reviews between them. What separates them is not really price. It is whether you want a small speedboat for a half day or a big cruise boat with lunch for a full one, and how many other people are aboard when you get there.

Before any of that, though, check you are booking the lagoon you think you are. Two different bays in this part of Croatia are marketed as the Blue Lagoon, and the mix-up is common enough that we have given it a section of its own below. If you want island hopping further out instead, that is the Blue Cave and five islands trip, a much longer day. For getting on the water under your own power, there is sea kayaking below Marjan instead, and for the evening version of a boat day, the Split boat party.

This is the single most common mistake made booking this trip, and it is easy to make because both bays are marketed under the same name in the same country.

Krknjaši, the one these tours go to

Krknjaši Bay lies between Drvenik Veli and two small islets, Krknjaš Veli and Krknjaš Mali, roughly 14 nautical miles west of Split and 8 from Trogir. It is shallow, sand-bottomed and sheltered, which is exactly why the water reads as that pale turquoise. It is reachable only by boat, and it is the bay every listing here means. Half-day trips from Split and Trogir are built around it.

Budikovac, the other one

Budikovac is a small island off the eastern side of Vis, far further out. Its lagoon is often called the Blue Lagoon too, and photographs of it circulate under that name, but you cannot reach it on a half-day trip from Split. It appears instead as a stop on the full-day Blue Cave and five islands tour, which runs 10 to 11 hours and is built around the cave on Biševo rather than the lagoon.

Our take (how to tell which one a listing means): Look for the island name rather than the words Blue Lagoon. Drvenik Veli, Krknjaši, Trogir, Šolta or Čiovo in the itinerary means the near lagoon and a half day. Vis, Biševo, Budikovac, Stiniva or Hvar means the far one and a full day at roughly double the price. If a listing says only Blue Lagoon and gives no island names, that is worth a question before you book.

What the Blue Lagoon and the standard three-island route actually look like on the water: the crossing out of Split, the colour at Krknjaši, the old town at Trogir and a stop on Šolta. Worth two minutes before you read the boat comparison below, because it shows how shallow and sheltered the bay is, which turns out to be the thing that decides which kind of boat can get into it.

All eight reach the same bay. What differs is the boat under you, the length of the day and what you are handed on board. We would settle the boat question before the price question, because it decides something no listing states: whether you finish the day in the lagoon or a few hundred metres outside it.

Every other variable on this page is small. This one is not, and the price ladder actively misleads about it.

What the ratings say

Four of the five speedboats rate 4.8 or 4.9. Not one of the three cruises clears 4.7. That pattern holds across more than 19,000 reviews, so it is not a small-sample artefact, and it runs directly against price: the cheapest options here are also the best reviewed.

How close the boat gets to the lagoon

Krknjaši Bay is shallow, which is precisely why the water is that colour, and a deeper hull cannot follow a shallow-draught one into it. One operator states this directly in a written reply to a complaint, saying the tour is run with a large boat which naturally cannot access very shallow water. Several guest reviews describe the consequence: anchoring a long way out, needing to be a confident swimmer to cover the distance, and in a few cases running out of the allotted swim time before reaching the turquoise at all. A speedboat goes in and stops inside the bay. That is the difference you are buying, and it is the one no photograph shows.

How many people are aboard

Crowding appears repeatedly in reviews of the larger boats. Guests describe sitting on the floor, sitting on beanbags while others step over them, and being counted into groups well over a hundred; one review recounts a boat so overbooked that some passengers were taken back off before departure. Speedboats cap at ten or twelve because they physically cannot hold more. The one cruise that publishes a capacity runs a 100 seat boat and boards up to 85. Nine hours with 85 people is a different proposition from five hours with ten.

How the clock runs

A large hull is slow, and manoeuvring it in and out of anchorages eats the day. Guests on the lower-rated cruises frequently report stops running short of the published figures, with the lagoon in particular coming in under an hour against an advertised ninety minutes. On an eight or nine hour day that is a lot of hours for not much swimming, and it compounds the anchoring problem rather than offsetting it.

Who each one suits

We would not choose a speedboat for anyone unsteady on their feet or prone to seasickness. Boarding is over the side, guests describe the ladder back aboard as genuinely awkward, and the ride throws spray across the whole boat. Otherwise, take the speedboat if you want the lagoon, want it quickly, and would rather eat in Trogir or back in Split. Take the cruise if you want a full day on the water with meals handled, are travelling with people who would find a five hour speedboat ride too rough, or simply want to sit still in the sun for nine hours. Both are legitimate days out and they are not the same one. Just go in knowing that, on the reports we read, the lagoon on the larger boats can be something you swim towards rather than sit in, and pick the better-rated cruise rather than the cheapest.

Our take (ask two questions before you book a cruise): First, does the boat enter the lagoon or anchor outside it? That single answer decides whether you swim in turquoise water or swim towards it. Second, how many people are aboard? Seven of these eight listings do not publish a capacity and the one that does is the largest. On a speedboat neither question matters, because the hull settles both. On a nine hour cruise at €85 to €90 a head they are the two things most likely to decide your day, and both are reasonable to put to an operator in writing before you pay.

The eight tours here span €70 to €90, a narrow band that hides two quite different products. Here is what the money actually buys.

• Check which Blue Lagoon the listing means. Krknjaši off Drvenik Veli is the half-day trip from Split; Budikovac near Vis is a stop on the full-day Blue Cave tour. Look for the island names in the itinerary rather than the words Blue Lagoon, because both bays are sold under the same name.
• Bring a towel. At least one of these tours states plainly that towels are not provided, and none of the speedboats list them as included. It is the most commonly forgotten item on a trip whose entire point is swimming.
• Pack lunch if you are on a speedboat. None of the five include food, though at least two pour unlimited wine and water on board. You get an hour in Trogir where you can eat, but that is also the hour you wanted for the old town. Something for the boat solves it.
• Carry cash for the island stops. Guests repeatedly report that the beach bar on the first island and some restaurants on Šolta do not take cards. It is the most commonly mentioned piece of hindsight advice on these tours and the easiest to act on.
• Take a waterproof bag, and take the speedboat only if everyone is steady on their feet. Spray comes over the whole boat at speed and guests describe the ride as genuinely wild rather than a gentle transfer. Boarding is over the side, and one guest found the ladder back aboard hard work. Anyone prone to seasickness should take something beforehand; several reviews raise it unprompted. The large cruise boats are the accessible version of this day.
• Pick your departure time on crowds or on colour, because you cannot have both. The water reads most vividly with the sun overhead, so midday is best for photographs. But the bay is small and shallow, and guests on early sailings report Trogir and the swim stops noticeably emptier while those on later ones describe a crowd of boats and the swimmers off them. Morning is the better trip; midday is the better picture.
• Ask a cruise operator whether the boat enters the lagoon or anchors outside it. The bay is shallow, and one operator states plainly when challenged that its large boat cannot reach very shallow water. Several guest reviews of the bigger boats describe anchoring a long way out and, in some cases, running out of swim time before reaching the turquoise at all. This is the single most useful question you can ask before paying for a cruise.
• Ask how many people are on board, too. Seven of the eight listings do not publish it, and the one that does boards up to 85. Guests on the busier boats describe sitting on the floor and on beanbags with others stepping over them. On a nine hour day that number shapes everything.
• Treat "unlimited drinks" on a cruise as water and squash. Several guest reviews of the lower-rated cruises describe the juice as watered down and the included wine as poor, and one five-star review says the same while still recommending the trip. If drinks are the reason you are paying more, that is worth knowing.
• On a big boat, watch the departure time yourself. A handful of guest reviews describe boats leaving swim stops early or setting off while people were still in the water. Note the stated return time, keep the boat in sight, and start swimming back before you are asked to.
• Consider departing from Trogir if that option exists. Trogir is 8 nautical miles from the lagoon against Split's 14, so a Trogir departure spends less of your day in transit. Two of these tours offer the choice.
• Do not treat the third stop as fixed. Several tours rotate between Maslinica, Labadusa, Čiovo beach bars and other bays depending on season and wind. If a particular village is the reason you are booking, confirm it rather than assuming.
• Reef-safe sunscreen and a hat. You are on open water with no shade on a speedboat for five hours, and the reflection off pale sand is stronger than it feels at the time.
• Go in June or September if you can. The lagoon is shallow and small, and in peak August it collects a lot of boats. Shoulder season gets you the same water with a fraction of the traffic.
