Blue Lagoon Boat Tour from Split: A Captain's Guide

If you have half a day in Split and you want to be in the water, this is the tour I run more than any other. It is also the tour people misunderstand before they board, because “Blue Lagoon” is used for more than one place on this coast.

This guide is the version I would tell you on the Riva if you asked what you are actually booking. The route, the two departure times, what €450 covers, and the cases where I would talk you out of it.

TL;DR

• Best for: A half-day in Split when swimming matters more than an island town.
• Departures: 9:00 or 14:00 from Trg Franje Tuđmana 1.
• Length: 5 hours. Morning boats are back around 14:00. Afternoon boats around 19:00.
• The swim: Krknjaši, the shallow bay between Drvenik Veli and the islet of Krknjaši.
• Also on the day: Trogir old town, then a quiet bay you can only reach by boat.
• Price: €450 for the whole boat online (the full boat price is €550), up to 9 guests. Not per person.
• What people miss: lunch is not included, and this bay is not the Blue Cave.

What the Blue Lagoon actually is

On this tour the Blue Lagoon is Krknjaši. It sits in the channel between the island of Drvenik Veli and the small islet of Krknjaši, roughly southwest of Trogir. The water is shallow, the bottom is pale, and on a sunny day it goes the turquoise colour that ends up on every brochure in Split.

You swim and snorkel there. You do not enter a cave. You do not take a dinghy through a low opening. If the photo in your head is a dark chamber lit electric blue, that is the Blue Cave on Biševo, and it is a different day.

Two other names cause the same mix-up. The full-day Blue Cave tour from Split also stops at a place we call a blue lagoon, on Budikovac. That is a good swim. It is not Krknjaši. And our Hvar day finishes with a swim at this same Krknjaši bay, after Hvar Town, the Pakleni Islands and lunch on Šolta. Same lagoon, much longer day.

The route, in plain English

This is the morning boat. The afternoon boat is the same shape of day, five hours later.

09:00 — Depart Split. We meet at Trg Franje Tuđmana 1, on the Riva. Life jackets out, a short briefing, then we leave the harbour. The first stretch is along the coast toward Trogir, and on a clear morning you can pick out the islands before you are properly out of the city.

09:30 — Trogir old town. Trogir is a UNESCO old town on a small island, joined to the mainland by bridges. On the morning boat you get it before the midday crush. Half an hour to an hour is enough to walk the stone streets and see the Cathedral of St. Lawrence. It is not enough to “do” Trogir. We are not trying to. It is the cultural stop. The swimming comes next.

11:00 — Blue Lagoon (Krknjaši). We anchor in the bay. The water is waist-deep in places and easy to read from the surface, which is why it works for nervous swimmers and for people who just want to float. Snorkelling gear is on the boat. Stay as long as the day allows — this is the reason you booked.

12:30 — Hidden bay. After Krknjaši we move to a quieter inlet on Drvenik Veli. There is no road to it. Pines come down to the water, and on most days you will see far fewer boats than you did at the lagoon. Guests remember this stop even though it is never the photo on the listing.

14:00 — Back in Split. You are ashore in time for a late lunch in town.

Hours move by 15–30 minutes with weather and with how long you want at each stop. The captain adjusts the day. The shape of it does not change: town, famous swim, quiet swim, home.

Morning or afternoon

Both slots are the same tour. They do not feel the same.

09:00 is the one I book for my own friends. Trogir is still waking up. Krknjaši has fewer boats on the mooring. You are back in Split by early afternoon, which leaves dinner, a walk, or another plan that evening. In July that also means you do the swim before the worst of the heat sits on the bay.

14:00 is the right boat when the morning is already gone — a late arrival, a flight, a walking tour of Diocletian’s Palace. You still get Trogir, Krknjaši and the hidden bay. You get them later. Trogir is busier. Krknjaši in the afternoon often has several other boats in the same bay. We can usually tuck into a quieter corner. You should not expect an empty cove. You are back around 19:00, which is a good time to go straight to dinner and a poor time if you had hoped to swim and then catch an afternoon ferry.

If both slots are open and you have no constraint, take the morning.

What €450 actually buys

The online price is €450 for the boat, not for a seat. The full boat price before the online saving is €550. Up to 9 guests. A couple pays the same boat price as a family of eight, which is why this tour starts to feel obvious once you are four or more, and why a couple should still compare it with how they want to spend the rest of the day.

Included:

• A private boat and an English-speaking captain. No other guests are added to your booking.
• Fuel, boat equipment, insurance and port taxes.
• Snorkelling gear for everyone on board.
• A 0.5 litre bottle of water each.

Not included: lunch, towels beyond what you are happy to swim with, and anything you buy in Trogir. There is no konoba stop on this itinerary. If a listing somewhere else promises “Blue Lagoon with lunch” for a similar price, read the hours. Lunch is how a five-hour tour becomes a nine-hour one.

Who should book this — and who should not

Book the half-day if any of these are true:

• You have one afternoon or one morning, not a full day.
• You came to swim, and a long open-water passage does not appeal.
• You are travelling with young children. Five hours, sheltered water and a shallow bay is an easier day than the Hvar run or the cave.
• You want to be back in Split for dinner, or you already have an evening plan.

Book something else if:

• You want the Blue Cave. That is the 10-hour Biševo day, with Stiniva, a different lagoon on Budikovac, the Pakleni Islands and Hvar Town. I compared the two directly in Blue Lagoon vs Blue Cave.
• You want a real island town and a long swim, and you have nine hours. That is the Hvar and Blue Lagoon day, which does finish at this same Krknjaši bay. The Hvar guide covers that route.
• You only have the evening. The sunset cruise is an hour and a half, and it is a different product.

For how all five of our days compare, the ranking is the short version.

This tour is suitable for children from age 3. It is generally not recommended if you are pregnant, have a serious heart condition, chronic back, neck or spine problems, or are recovering from recent surgery. If that is you, tell us before you pay a deposit. The captain can refuse a trip when it is the safer call.

What to bring

• Swimsuit. You will use it twice.
• Sunscreen, a hat, sunglasses. Wind on the boat hides how much sun you are taking.
• A light layer. The run back can be cooler than the bay, especially outside July and August.
• Cash or a card for Trogir if you want a coffee. Nothing on the boat needs paying once the tour is booked.
• A dry bag if your phone is not one you are willing to drop. The water is clear enough that people lean too far over the side.

You do not need to bring snorkelling gear or drinking water.

When to come

We sail from 1 April to 1 November.

The water at Krknjaši is swimmable earlier than people expect, but the day I would pick for a first visit is late May through mid-June, or September. The bay is itself, the town is open, and you are not sharing the mooring with every boat that works out of Split, Trogir and the Drvenik islands.

July and August are the warmest and the busiest. Book the morning slot, and book it ahead. The lagoon does not close in high season. It just fills up.

Early October still works on settled days. After 1 November we are not running this tour.

Weather still cancels days in every month. If the sea is unsafe we reschedule or refund. Details are in the booking section below.

Booking and what happens next

The Blue Lagoon half-day is booked on the tour page.

1. Choose a date and either the 9:00 or the 14:00 slot. Pay a 20% deposit.
2. We confirm and send the meeting point, the captain’s name and a direct WhatsApp number.
3. The day before, we look at the forecast. If it is marginal, we say so.
4. You meet us at Trg Franje Tuđmana 1, ten minutes before departure.
5. A short safety briefing, then we leave.
6. The remaining balance is due on arrival, before we cast off.

If we cancel because the weather is unsafe, or because of force majeure, you can take a full refund of the deposit or move the date. That choice is yours, as long as the call is made up to 24 hours before departure. If you cancel for any other reason, the 20% deposit stays with the booking and the balance is not charged. The full wording is on our cancellation page.

If you are still unsure whether you want this bay or the cave, read the comparison before you pay the deposit. They are both worth doing. They are not substitutes.
