Sliema: Powerboat to Comino Caves & Blue Lagoon with a Swim
Book on GetYourGuide →Operated by Supreme Power Boats · Bookable on GetYourGuide
Comino by powerboat feels like a theme-park sprint. You’ll blast out of Sliema with loud music and big sea energy, stop at Santa Maria Caves for quick photos, then land at the Blue Lagoon with time to swim. This is a fast, fun way to see the Comino highlights without spending hours on a slow ferry.
The trade-off is real: the ride can be bumpy, and the lagoon can be crowded with limited shade on rocky ground. If you’re sensitive to jostling, or you want a quiet beach day, you might find this style of tour less comfortable.

Meeting in Sliema: finding the boat and what to expect at check-in
You’ll meet at the Sliema Ferries area, right opposite McDonald’s. Since there’s no hotel pickup, plan to get there on your own and give yourself a few minutes buffer.
Before boarding, everyone must sign a waiver form. It’s a simple step, but it’s one more reason to show up early instead of last-minute rushing.
The Supreme Power Boats ride: speed, music, and how rough it feels
This tour’s main selling point is the boat itself: Supreme Power Boats is built for speed, and the trip is described as music-filled and thrilling. Think of it as an in-your-face crossing rather than a relaxed transfer.
Is it smooth? Not really. Multiple people call out a bumpy ride, and there’s a decent chance you’ll get wet depending on your seat and sea conditions. One practical tip I picked up: if the captain explains seating, the back of the boat tends to be less bumpy than the front.
Also, match your expectations to the vibe. This is not a quiet, “whisper-guided” cruise. If you like momentum, tunes, wind in your face, and a bit of chaos-in-a-good-way energy, you’ll probably love it. If you don’t, you may find it harder to enjoy the ride as a ride.
Santa Maria Caves photo stop: the quick hit before the big swim

Right after departure, you’ll make a stop for about 20 minutes at Santa Maria Caves. This is set up as a photo and sightseeing moment—scenic views from the water, and a chance to see coastline details before heading deeper into Comino territory.
What this stop does well is timing. You get a taste of the caves and the dramatic coastline without sacrificing the longer swim window at the Blue Lagoon. The downside is that it’s quick. If you were hoping for lots of time to linger and explore, you’ll need the main Comino portion for that.
Comino Blue Lagoon: 4 hours to swim, snorkel, and hunt for your spot
Your biggest block of time is at Blue Lagoon (about 4 hours). This is where the water reputation becomes real: clear, bright, and built for photos that actually look like the postcards.
You’ll have time to swim and snorkel, and you can also spend time just hanging out, taking in the cliffs, and walking around if you want views from the shore trails. Some people also point out that there are food and drink options plus toilets on Comino, which matters when you’re there for several hours.
Now the part to plan for: crowding. The Blue Lagoon can get packed, and shade can be hard to find because you’re often dealing with rocky ground. One smart workaround is to treat your plan like a water-based day, not a lounge-on-a-towel day—meaning you’ll likely spend more time in the water and hop between swim and short breaks on land.
If you care about comfort, consider this packing advice from people who’ve done it: wear sea boots if you have them. The rocks can be sharp, and it makes getting in and out of the water a lot less annoying. Also bring sunscreen, water, and sun protection like a hat and sunglasses—Comino sun is a serious factor.
Snorkel gear: bring it or plan to rent
Snorkeling is part of the experience, but snorkel gear is not clearly listed as included. One note you should know: snorkel gear may not be provided as part of the tour package, though rental can be available once you reach Comino. If snorkeling is your top priority, I’d assume you’ll either want to rent gear on-site or bring your own.
Crystal Lagoon caves and the cave tour: seeing Comino from the water

In addition to the Santa Maria stop, the tour includes Crystal Lagoon Caves and a cave tour. This is where the experience becomes more than just beach time. You’ll be shown the cave areas by boat, which can be better for photos and access than trying to reach everything from shore.
One caution: cave time can feel limited. Some people note that the cave portion may be shorter or less extensive than expected, especially if you compare it to other famous grotto experiences. If you’ve seen places like the Blue Grotto before, it helps to go in with a “watch from the water, enjoy the scenery” mindset instead of expecting an extended inside-cave adventure.
Why this tour is often better value than the regular ferry
The price is about $70 per person for roughly a 6-hour experience, and it includes things that matter for a boat day: a local expert captain, safety equipment, fuel, and the cave elements tied to Comino. Food and drinks are not included, so you’ll still want to budget for that once you’re there.
So is it worth it? For a lot of people, yes—because it changes the whole rhythm of the day. A powerboat gets you there quickly, and you spend more of your day doing the things you booked for: swimming time, cave viewing from the water, and the Comino coastal scenery.
It’s also a good option if you want to avoid the most crowded “sit and wait” feeling of slower transport. Even if you still end up with crowds at Blue Lagoon (you probably will), at least your travel time isn’t eating your holiday.
Who should book this powerboat day (and who should skip it)
This is an adventure-style outing. It’s best for people who enjoy speed and don’t mind a bit of bouncing on open water.
It’s not suitable for:
- children under 3 years
- pregnant women
- people with back problems
- people with heart problems
- wheelchair users
- people with recent surgeries
- people over 95 years
Also, if you get motion sick easily, you’ll want to think twice, since the ride is described as bumpy and thrilling. On the flip side, if your goal is a lively Comino day—sea caves up close, a big swim window, and the fastest route—this matches the intent.
Families: doable with the right expectations
Families do book it, including people with teenagers. The key is managing expectations: the tour isn’t a slow sightseeing cruise, and Comino’s beach time can be crowded and rocky. If your group includes kids who can handle wind, speed, and water time, it can work well.
What’s included in the ticket, and what you’ll need to pay for
Here’s how the $70 value breaks down:
Included:
- local expert captain
- full safety equipment
- liability insurance and local taxes
- fuel cost
- 4-hour stop at the Blue Lagoon for swimming
- Crystal Lagoon Caves
- cave tour
Not included:
- hotel pickup and drop-off
- food and drinks
One more practical note: since snorkeling is part of the plan, think about whether you’ll have gear. If you don’t bring it, plan to rent it once on Comino, if available.
Practical packing checklist for Comino sun and rocky entry
If you want the easiest day at Blue Lagoon, pack like you’re going to be in and out of water repeatedly. At minimum, bring beachwear. Beyond that, here’s what I strongly recommend based on what people actually say helps:
- sunscreen and sun protection (Comino sun is intense)
- water (you’ll be out for hours)
- a hat and sunglasses
- sea boots if you have them (rocks can be sharp)
- a plan for crowding: towel, quick-dry items, and something easy to manage on rocky ground
Also remember the waiver. It’s required before boarding, so keep your group ready to sign and move.
Weather, sea mood, and the crowd factor (so you don’t waste your time)
This tour’s comfort level depends on sea conditions. On calmer days, the ride may feel like thrilling speed. On rougher days, it can feel more like controlled chaos—still fun for many, but not for everyone.
For the lagoon, timing matters. You depart at 11:00, which can help you arrive before the peak rush, but the Blue Lagoon is still a magnet. The smartest mindset is: plan to swim a lot, don’t bank on finding a perfect shaded lounging setup, and be ready to improvise with where you land.
If you care about less crowd stress, also consider doing short walks for views while others are settled on towels. Those cliff views and coves are part of the payoff, and moving around can help the day feel less like waiting for your turn.
Should you book this Comino powerboat tour?
Book it if:
- you want a fast, lively way to reach Comino
- you like speed and don’t mind loud music and wind
- swimming in clear water is your main goal
- you’re excited about seeing sea caves from the water and getting a structured cave experience
Skip or reconsider if:
- you’re sensitive to bumpy rides or getting wet
- you want lots of quiet time and a lot of personal space at the beach
- you don’t want to deal with crowding and rocky entry points
If your group matches the “adrenaline + swim + caves” plan, this is one of the most fun ways to do Comino in a single day. The boat ride is the headline, and the lagoon time is the prize—just go in knowing the lagoon can be busy, and come prepared to make the most of your water time.
