Blue Lagoon and Trogir speedboat tour from Split — honest half-day review

The best half-day on the water near Split

The Blue Lagoon tour solves a common problem: you want a swimming day on the Adriatic but the multi-island, all-day speedboat tours feel like too much of a commitment. The Blue Lagoon format — typically 4–5 hours, departing mid-morning and returning before early afternoon — delivers a high-quality water experience without consuming an entire day.

The lagoon itself sits between Drvenik Mali island and the tiny islet of Krknjaši, 25 km west of Split. The cove is naturally sheltered by the surrounding islands, creating water that is shallow (1–3 metres over most of the swimming area), turquoise, and clear to a sandy bottom. The colour in ideal morning light is genuinely extraordinary — the kind of blue that prompts people to check whether the photos have been filtered.

Full-day tours combine the lagoon with stops in Trogir old town and usually one or two additional island or swimming points on the way back. Half-day tours focus on the lagoon and a quicker Trogir stop.

What the full-day tour includes

The most popular format — the Mediterranean lunch version — runs approximately 8–9 hours:

09:00: Depart Split (Riva waterfront or nearby pier).
10:00: Blue Lagoon arrival. Swimming, snorkeling, optional kayak or paddleboard (some tours include). Morning light here is exceptional — arrive before the second wave of boats.
11:30: Depart for first island stop (often Čiovo or a smaller islet).
12:30–13:00: Arrive Trogir. Guided walk of old town (30–45 minutes) or free exploration.
14:00: Lunch on board or at a Trogir restaurant. Mediterranean menu: grilled fish, salad, local wine or soft drink.
15:30–16:00: Return to Split via scenic coastal route.
17:00: Arrive Split.

Why Trogir deserves more than a 45-minute stop

Trogir gets undersold as a “quick stop” on boat tours from Split, but it deserves better. The old town is a medieval Venetian island city — literally on a small island connected to the mainland and Čiovo island by bridges — with a density of Romanesque and Gothic monuments that surprises most visitors who come expecting another pleasant Croatian town.

The Cathedral of Saint Lawrence has a west portal carved by Master Radovan in 1240 that art historians rank among the finest examples of Romanesque sculpture in the Adriatic. The Kamerlengo Fortress has views over the waterfront. The loggia and town hall square have the proportions of Venice with a quarter of the crowds.

If Trogir genuinely interests you, consider a dedicated half-day trip rather than a 45-minute speedboat stop. Our Trogir half-day trip guide and Trogir old town guide have the full detail.

Comparing the main tour formats

A smaller vessel (8–12 passengers vs 20–30 on the larger catamaran-style boats). The smaller speedboat gets you closer to the lagoon entrance and into the cove more efficiently. Best for those who value a less crowded experience.

The straight half-day format — 4.5 hours, lagoon swimming and a quick Trogir stop. Ideal if your afternoon is committed (other tours, long lunch in Split, evening ferry). Lower price point than the full-day version.

Adds the island of Čiovo (connected to Trogir by bridge) with a swimming stop at one of Čiovo’s coves. Good if you want an additional swim stop beyond the lagoon within a half-day format.

Price breakdown

Half-day tour (4–5 hours): €35–55 per adult
Full-day with lunch (8–9 hours): €65–90 per adult
Private speedboat (4–6 people): €200–400 depending on duration and itinerary

The full-day with lunch version represents good value if you compare it to: speedboat charter individually (~€150–200/hour), Trogir bus trip (€6 each way but no water time), and a separate beach afternoon. The combined boat tour + Trogir + lunch in a single day for €65–90 is efficient.

Crowds and the best time to go

The Blue Lagoon’s main challenge in July–August is crowds. Multiple operators run concurrent tours; by 11:00–12:00 the cove can have 20–40 speedboats anchored within a small area, with swimmers everywhere. It is still beautiful — the water quality is not diminished by boats — but the atmosphere shifts.

Best months: May and September. The water temperature is 20–22°C (still comfortable for swimming), the lagoon has a fraction of the summer crowds, and the surrounding islands are at their most photogenic with clear air.

Best departure time: 09:00 departures consistently report arriving at the lagoon before the main rush. 10:00–11:00 departures encounter significantly more company.

Who should book the Blue Lagoon tour

Strong match: Families with children (the shallow, calm water is ideal for young swimmers), couples wanting a relaxed half-day boat experience, visitors who want swimming without a 10-hour all-day commitment, anyone who has not visited Trogir yet.

Consider alternatives instead: Travellers who have already been to Trogir and want a different island; active travellers wanting kayaking or snorkeling with more depth (the Pakleni Islands are better for that); visitors prioritising the Blue Cave and Hvar islands (the five-islands speedboat tour is a better fit).
