The boat rounds the western point of Comino, the engine drops to a low rumble, and the colour of the sea changes. One minute you’re looking at proper Mediterranean blue, the deep open-water kind. The next, the seabed jumps up into focus, white sand a few metres below the hull, and the water turns a turquoise so improbable it looks like someone tipped pool dye in by mistake. That is the payoff. Everything before it (the marina pickup, the safety briefing, the 45-minute sail across the channel) was queueing for this single moment.
If you only have time for one Malta excursion, this is it. The Blue Lagoon between Comino and Cominotto is the country’s flagship water experience, and the day boats that run there from Sliema, Bugibba, and Mgarr are how almost everyone arrives.
Best from Sliema: Sliema to Comino, Crystal Lagoon and Blue Lagoon Cruise, $41. Picks up right on the Sliema waterfront, hits both lagoons plus the caves.
Best catamaran: Blue Lagoon, Beaches and Bays by Catamaran, $60ish. From Bugibba, on a newer cat with food and drinks included. Less bumpy than the powerboats.

What the Blue Lagoon actually is
Comino sits between Malta’s main island and Gozo. It’s tiny (3.5 square kilometres), almost uninhabited, and the only reason most people visit is the water. The Blue Lagoon (Bejn il-Kmiemen in Maltese, “between the two Cominos”) is a shallow channel between Comino and a smaller rock called Cominotto. The seabed is white sand. The cliffs on either side are limestone. Sun hits the sand, bounces back through clear water, and you get that postcard turquoise.
It’s not large. You can swim from one side to the other in about eight minutes. The water is shallow enough in the middle that small kids can stand in some sections. Visibility is comically good, often 30 to 50 metres on a calm day, which makes snorkelling dead easy without much skill.
The catch is no one has it to themselves. By 11am in July or August, you might be one of fifty boats moored within sight of each other. Malta capped daily visitors after 2023 because the cumulative numbers had gotten silly (around 12,000 a day at the 2018-19 peak). That helps but doesn’t solve it. If you want photos that look like the marketing brochure, you need to either get there early or shift your trip outside July and August. More on timing below.
The three boat options that actually matter
Hundreds of operators run trips. They sound similar in the descriptions and they’re not. The differences come down to four things: where you depart from, how long you’re out, whether you stop inside the sea caves, and what kind of boat it is. Pick the one that fits your day.
1. Gozo, Comino and Blue Lagoon Day Cruise: $28
This is the workhorse. A full-day cruise that does Gozo, Comino, the Blue Lagoon, the Crystal Lagoon, and the sea caves on a larger boat for not much money at all. Pickup is from Sliema or Bugibba depending on which slot you book, and our full review walks through which departure suits each base. The short version: this is the trip to book if you only have one day to spend on the water and you want to see Gozo as well as the lagoon.

2. Sliema to Comino, Crystal Lagoon and Blue Lagoon Cruise: $41
The Crystal Lagoon stop is the difference here. Most cheaper trips skip it because it’s tucked under cliffs on the Comino side facing Malta, and you have to know where to slow down. Crystal is smaller, deeper, less crowded, and weirdly photogenic. The crew runs out of Sliema’s main waterfront, so you avoid the bus or taxi up to the north of the island. Worth the extra few quid if you’re based on the eastern coast, and our review goes deeper on what the Sliema pickup actually saves you in time.

3. Blue Lagoon, Beaches and Bays by Catamaran: $60ish
This is the upgrade pick. It’s a newer catamaran out of Bugibba (so booking from the north is much easier than from Sliema), with food and drinks included, and a measurably more comfortable ride than the old wooden boats. The route hits the Blue Lagoon, the Crystal Lagoon, the Comino caves, and a stop near Popeye Village in Mellieha Bay on the way back. If the budget allows, do this one. Our review breaks down why the boat itself becomes the experience as much as the destination.

The cheaper option no one writes about: the Cirkewwa ferry
Quick honest aside before the main article continues. If you’re on a tight budget and you only want to swim at the Blue Lagoon (no caves, no Crystal Lagoon, no lunch), skip the cruises entirely. The Comino Ferries shuttle from Cirkewwa on the north of Malta is roughly 14 euro round-trip for adults, runs every 30 to 60 minutes in season, and gets you from car park to lagoon in about 25 minutes. You sit on the rocks, swim, eat the food-truck pastizzi, and ferry back when you’ve had enough. No frills. Tons of locals do this on weekends.
Why book a cruise instead? Because the ferry won’t take you into the sea caves, and it won’t stop at the Crystal Lagoon. You also won’t get the swimming-from-the-deck experience or any kind of guided narration. If those things matter, book a cruise. If they don’t, take the ferry and pocket the difference. Both options are genuinely fine.
Sea caves: why the smaller boats win
Comino’s coast is studded with sea caves cut into the limestone. The Santa Marija caves are the headline ones, but there are also smaller arches near the western point and a couple of short tunnels you can boat through. The catch: only smaller boats actually go inside. The big day cruisers slow down outside and let you take photos from the deck. The catamarans, the powerboats, and the schooners (the 38-metre two-masted Hera that runs out of Valletta) actually nose in.
If sea caves are a priority, ask before you book. Look for “enters caves” or “stops inside caves” in the listing description. Otherwise you’ll be the person standing at the rail wondering why the boat won’t move closer.
Best time to go
The honest answer: May to June and September to October. The water is warm enough (22 to 25C in May rising to 26C in June; still 24 to 25C through September), the lagoon doesn’t get crowded the way it does in July and August, and the heat is bearable on the boat deck. We’d actively avoid mid-July through late August. The water itself is fine, but the Blue Lagoon turns into a parking lot of moored boats by 10am, the shore is shoulder-to-shoulder sunbathers, and the photos look like an event.
July and August are not unworkable. They’re just less rewarding than the shoulder months for the same money. If you’re locked into a summer holiday window, book the earliest morning departure you can find (around 9am pickup) so you arrive at the lagoon before the bigger boats.
Winter (December to February): a small but loyal contingent does this trip year-round. Water sits in the high teens, which is too cold for most people. The lagoon is empty, the sky is bluer than summer, and the cliffs look more dramatic in the lower light. If you’ve got a wetsuit and like that particular kind of off-season satisfaction, go for it. Cruise schedules thin out, so check before you fly.

Where you’ll get picked up
Three main ports. Each suits a different base.
Sliema is the most common. Almost every cruise picks up somewhere along The Strand. If you’re staying in Sliema, St. Julian’s, or Valletta, this is the easy choice (you can walk or take a five-minute Bolt). The downside is the boat then has to cross most of Malta’s coast to reach Comino, which adds 45 minutes to an hour each way.
Bugibba sits at St. Paul’s Bay on the north side, much closer to Comino. Cruises from Bugibba reach the lagoon faster, which means more swimming time and less sailing. If you’re based at one of the resort hotels in Bugibba, Qawra, or St. Paul’s Bay, book from here. The Malta National Aquarium is right there too if you want to combine a half-day at the aquarium with an afternoon cruise.
Mgarr (Gozo) is the option if you’re already on Gozo for a few nights. The crossing is shorter than from Malta, prices are sometimes a bit lower, and several cruises do a Gozo-Comino loop that lets you sleep on the bigger island. Our Gozo guide has the full breakdown if you’re considering basing there for a couple of nights instead of doing it as a day trip.
What to bring (the things you’ll regret forgetting)
The list is shorter than the average travel blog makes it. The non-obvious stuff:
- Reef-safe sunscreen. Maltese sun in June is no joke, the water reflects, and you’ll burn the tops of your feet on a 7-hour deck day. Bring more than you think.
- A dry bag for your phone, wallet, and a change of clothes. The boat lockers are usually shared and not always dry. 10 euro dry bag, total game-changer.
- Snorkel and mask. Some cruises hand them out, plenty don’t. Visibility in the lagoon is so good that snorkelling in your own kit beats any guided activity. Decathlon in Sliema sells a basic set for under 15 euro.
- Cash for the food trucks at the lagoon. The boat lunch (if your cruise includes one) is usually fine, not amazing. The pastizzi from the food trucks on the Comino shore are better. Bring small euros.
- Long-sleeved layer. The wind on the open channel can be cold even in July, especially on the catamarans where you’re sat at sea level. A thin layer earns its keep.
- Water shoes if you’re sensitive-footed. The seabed is mostly sand, but the entry points are limestone and the rocks have urchins.
What you don’t need: cameras with massive lenses (your phone is fine, the colour does the work), bulky beach umbrellas (the boat shades you, the lagoon shore has rentals), or anything resembling formal wear. This is a wet, salty, sandy day.
Crystal Lagoon: the one most boats skip
If you’ve got a choice between two cruises with similar pricing, take the one that includes Crystal Lagoon. It’s a small inlet on the Malta-facing side of Comino, ringed by 30-metre limestone cliffs that block the sun until late morning. The water is darker and deeper than the Blue Lagoon, the kind of saturated cobalt that doesn’t photograph well but feels even bluer in person. There’s no beach. You swim straight off the boat.
Why most operators skip it: it requires a manoeuvre into a narrower bay, and the larger ferries can’t get in. So the Crystal Lagoon stop is a marker of a smaller, better-handled boat. If your cruise listing doesn’t mention it, your captain probably won’t go in.
The history bit (skip if you’re just here for the swimming)
Comino has a population of two. Officially. There’s a small chapel, a hotel that opens seasonally, an isolation hospital that hasn’t been used in a century, and St Mary’s Tower, a 1618 Knights of St John watchtower built to keep an eye on Ottoman ships moving through the channel. The Knights also farmed cumin on the island (where the name Comino probably comes from) and used the rocky interior as a punishment station for misbehaving knights.
Your cruise won’t take you up to the tower (it’s a 20-minute walk uphill from the lagoon and you’d have to organise your own time) but you can see it on the cliffs above the Blue Lagoon if you look up while swimming. If you’re the type who likes adding a short hike, the day-cruise schedules typically give you 2 to 3 hours at the lagoon, which is enough time to walk up, take a photo, and walk back down with time to spare.
Things people get wrong
Three rookie mistakes I see almost every trip.
First: treating it like a beach day at home. The lagoon shore is rocky limestone, not sand. The little sand beach is maybe 25 metres long and gets territorialised by 9am. Plan to swim, snorkel, and use the boat as your base, not the shore.
Second: showing up at noon expecting empty water. Most cruises pick up between 9am and 10am, which means everyone arrives at the lagoon between 10:30 and 11:30. If you want even a slightly less mobbed experience, the trick is the late-afternoon shuttle ferries from Cirkewwa. After 3pm the day boats start packing up and the lagoon empties out. The water and light are also better in late afternoon than at midday.
Third: not checking the wind forecast. Malta’s Maestral wind picks up in summer afternoons, and the channel between Malta and Comino can get choppy. If you’re prone to seasickness, book a morning departure (calmer water) and a catamaran rather than a powerboat. Single-hull boats roll noticeably more in any kind of swell.
Combining with other Malta trips
The Blue Lagoon eats a full day. You won’t have energy for anything else after a 7-hour boat day, you’ll be salty, sun-tired, and probably a little dehydrated even if you drink plenty. So plan it as a standalone day. The natural pairings, on either side of it:
Day before or after, pair with a Valletta walking tour (the capital is small, two hours covers it, and you can fit it around an early dinner). Or do the Mdina and Malta highlights day on a different day, that one is full-on inland and historical and stays inside the bus, no overlap with the Blue Lagoon at all.
If you’re travelling with kids who’ll have hit their boat-day limit, the Malta National Aquarium at Qawra is a good rest day. You see the same Mediterranean species you snorkelled past at Comino but at proper scale and with labels, which is weirdly satisfying. Popeye Village in Mellieha works for younger kids too, and several Comino cruises actually pass it on the way back.
For deeper exploration of the third Maltese island, our Gozo guide covers the multi-day option, where you stay on Gozo a couple of nights and treat the Blue Lagoon as a half-day boat from Mgarr instead of a full-day cruise from Malta. That’s the sleeper itinerary if you’ve got 7+ days in the country.
Booking notes
A few specifics worth knowing before you click book:
Weather cancellations are real. Cruises run on the Med, the Med has bad days, and operators will cancel if the captain isn’t comfortable with the swell. Book the version with free cancellation up to 24 hours before, and if there’s any doubt about the weather, watch the forecast the day before. You usually get a refund, but rebooking on the same trip in peak season can be tight.
Lunch isn’t always lunch. Many cruises advertise “lunch included” and what arrives is a packed bread roll and a piece of fruit. The catamaran at $60 actually has a hot meal. The cheaper cruises don’t. If food matters to you, read the inclusions list carefully or just plan to eat on the Comino shore.
Pickup from your hotel is occasionally offered as an upgrade and almost never worth it. Maltese taxis are cheap, the Bolt app works fluidly across the island, and the cruise pier is usually 10 minutes from any beach hotel. Skip the upgrade.
Last-minute bookings are usually fine outside July and August. Same-day departures are even possible in May and September. Don’t panic-book the trip months ahead unless you’re locked into a specific date and a specific operator.
Other Malta booking guides worth a look
If you’ve got more than just a day, the obvious next layer is a Mdina and Malta highlights day for the inland history (the Silent City is a five-minute walk from medieval to Game of Thrones-shooting-location), and a Valletta walking tour for the capital itself. Popeye Village is the wildcard pick if you have kids or a soft spot for 1980s film sets, and the Malta National Aquarium is the easy half-day if a beach day didn’t pan out.
For travellers who like a Mediterranean island-hop angle, the Capri boat trips from Naples follow a similar half-day cruise pattern, and the Amalfi Coast boat options are the closest thing to the Blue Lagoon experience over in Italy. Different water, similar feel.
