Sliema to the Blue Lagoon: the maximum-swim-time cruise

Every other full-day boat on our list departs from Malta's north, which is perfect if you stay there and a logistics exercise if you do not. The Sliema Blue Lagoon cruise leaves from the Sliema ferry dock in the heart of the tourist coast, so if your hotel is in Sliema, St Julian's or Valletta, this boat spares you a long bus ride to the northern jetties before your day even begins. The crossing to Comino is longer at 70 to 90 minutes, but it turns into a scenic cruise past Valletta's fortifications and the northern bays rather than dead time on a coach.

The operator's own promise is simple and worth taking at face value: the aim is the maximum amount of swimming and snorkelling time at the lagoon. Sightseeing happens on the way, with a photo stop at the Crystal Lagoon and views of Comino's sea caves, rather than eating into your anchor time. If your idea of a good day is hours in clear water rather than a checklist of stops, this is the design that delivers it.

Board at Sliema Ferries for the 10:30 departure. The cruise up the coast takes in Valletta from the water, then the open channel crossing to Comino. Once anchored at the Blue Lagoon, the day is yours: swim, snorkel, float, or claim a deck chair and do absolutely nothing. The shallow sand bank between Comino and the islet of Cominotto gives the water its swimming-pool clarity, and the channel on the Cominotto side offers quieter snorkelling than the main beach.

When you need a break from the sun there is an air-conditioned lounge below deck with a bar selling snacks, ice cream and drinks. The boat starts back in the late afternoon and ties up in Sliema at 18:30, which puts you back at your hotel in time for dinner. That full eight-hour window is the longest lagoon-focused day among the tours we track.

To step ashore on Comino at the Blue Lagoon, Malta now requires a free access pass: an online registration on the government portal blcomino.com that returns a QR code for your date. It is a registration system to manage crowds, not a paid ticket, with a daily cap of around 4,000 visitors. The pass applies to going ashore, not to swimming from the boat.

Because this cruise is built around swimming from the vessel, most passengers never need it. If you plan to walk on the beach, register a few days ahead in peak season, when the popular slots sell out. It is a small admin step that catches out visitors who leave it to the day, so sort it the night before if the beach is part of your plan.

The 25 euro base fare covers the day cruise itself with the full 10:30 to 18:30 sailing. On board you will find the air-conditioned lounge, upper sun deck and a bar. Not included: spirits, gratuities and the optional powerboat cave tour sold on the day. Drinks and food are pay-as-you-go at the bar.

Set against the rest of the market, this sits in the same 24 to 30 euro full-day band as the classic loop and the catamaran, but it buys a different thing: departure convenience for the Sliema side plus the longest anchor time, rather than Gozo or deck space. The base rate is what we verified on 2026-07-13; use the live calendar below for your exact date's price.

This boat earns its keep most in July and August, when the air-conditioned lounge stops the day from becoming an endurance event. For lighter crowds at the lagoon, June and September remain the smart months; the eight-hour day feels even better when the anchorage is not packed. In peak summer the lagoon is busiest between roughly 11am and 4pm, so the long anchor here means you are still there as the day boats begin to thin in the later afternoon.

If avoiding crowds is your priority above all, weigh a sunset sail instead: our sunset cruise guide covers the evening option, and our best-time-to-visit guide breaks the whole season down month by month.

Departure is from the Sliema ferry dock, the same waterfront strip served by buses from every direction and a short walk from most Sliema and St Julian's hotels. That accessibility is the entire argument for this boat: no transfer north, no early coach. Arrive fifteen minutes early in peak season; your booking confirmation restates the exact berth.

For context on the area and its connections, see Sliema on Wikipedia and the official Visit Malta transport pages.

This boat suits three kinds of visitor especially well. Anyone staying on the Sliema, St Julian's or Valletta coast, for whom the departure point removes a long transfer north before the day even starts. Dedicated swimmers who found the multi-stop itineraries too rushed and want to spend real hours in the water rather than ticking off caves. And anyone travelling in the peak of summer who values the air-conditioned lounge as a genuine refuge from the midday heat, which few other boats offer.

It is a weaker fit for a few groups. If you want to set foot on Gozo, this route does not cross the channel to it, so a combined cruise or the classic loop serves you better. If restlessness at sea is a problem, the 70 to 90 minute crossing each way is longer than the northern boats and worth factoring in. And if your priority is a party atmosphere or a waterslide rather than quiet swimming time, the sunset and catamaran boats lean more that way. Matched to the right traveller, though, the single-minded focus on lagoon time is exactly what makes this cruise stand out.

Pack your snorkel: this itinerary gives you more in-water hours than any other boat on the list, and rental gear on Comino costs more than bringing your own. The air-conditioned lounge fills up in the afternoon heat, so stake your spot before the crowd thinks of it. Bring a towel and reef-safe sunscreen, and buy water on board or carry your own.

Manage expectations on the crossing: it is longer than the northern boats, so if you or your children get restless at sea, factor that in. And if you want to combine the lagoon with Gozo, this is not the boat for it, since it focuses entirely on Comino; our Gozo and Comino day trip guide covers the two-island options instead.

One more note on the long day: the eight hours from 10:30 to 18:30 include the 70 to 90 minute crossing each way, so your actual time anchored at the lagoon is what matters, and this boat maximises exactly that. Bring something for the crossing, keep topping up sunscreen through the long exposure, and pace the bar so it lasts the whole day rather than the first hour.
