The short verdict
Worth going out of your way for, but only if your boat actually stops. The Crystal Lagoon is the better swim of the two Comino lagoons on almost any day in summer, and most visitors to Comino never see it. The catch is entirely logistical: you cannot reach it on the ferry ticket that gets everyone else to the island, and plenty of trips advertised with a photograph of it only slow down as they pass. If you cannot swim confidently in deep water with nowhere to stand, this is not your stop.
What it actually is
A narrow inlet on the far side of Comino from the Blue Lagoon, cut into the rock and walled on both sides by pale cliffs that go straight down into the water. There is no beach. There is no shallow end. The floor drops away immediately, which is exactly why the water looks the way it does.
That is the difference worth understanding before you choose between the two. The Blue Lagoon is turquoise because it is shallow over pale sand and the light bounces back up at you. The Crystal Lagoon is a deep, clear, dark blue for the opposite reason: there is nothing underneath to reflect. People arrive expecting a second turquoise bay and get something closer to swimming in a flooded quarry, in the best possible sense.
Why you cannot just walk there
This is the single most useful thing on this page. The overwhelming majority of people who go to Comino take the passenger ferry from Ċirkewwa, which lands at the Blue Lagoon and goes nowhere else. From there, the Crystal Lagoon is on the other side of the island, behind cliffs with no usable path down to the water.
So it is a boat stop or it is nothing. Either book a trip that circles Comino and calls there, or hire something small enough to take you. The ferry crossing and a Comino boat trip are two different purchases, and confusing them is how people end up on the island all day without ever seeing the thing they came for.
What the swim is like
Cold at first, noticeably colder than the Blue Lagoon shallows, because depth does that. Very clear, with good visibility straight down, and quiet in a way the Blue Lagoon never manages in July. Sound behaves oddly between the rock walls.
You get in from the boat and you get out onto the boat. There is nowhere to leave a towel, nowhere to stand and rest, and nowhere to retreat to if the swell picks up, so it suits confident swimmers and it does not suit small children. Most operators put a ladder down and some hand out floats; neither is guaranteed.
What to check before you book
Three things, in order of how often they catch people out.
Does the itinerary say you stop, or only that you visit? A pass-through counts as a visit in marketing language. If swimming here is the point, look for a stated swim stop.
How long is the stop? Short calls are normal on a circuit, and twenty to thirty minutes is a realistic expectation rather than a complaint. Plan to be in the water within a minute of the engine cutting.
Is it bundled with the caves? Most Comino circuits pair this with Santa Marija Caves, which is the right pairing and better value than either alone. If a trip includes only one, it is usually the caves.

Common questions
Can you walk to the Crystal Lagoon from the Blue Lagoon?
Not in any practical sense. It is on the other side of Comino, behind cliffs, with no usable path down to the water. The passenger ferry that lands everyone at the Blue Lagoon does not go there, so a boat trip is the only way in.
How is it different from the Blue Lagoon?
Shallow sand versus deep rock. The Blue Lagoon is turquoise because you can nearly stand in it. This one is dark, clear blue because the bottom drops away at once. Different colour, different swim, and usually a fraction of the people.
How long will the boat stop for?
Often twenty to thirty minutes, as one call on a circuit. That is normal rather than stingy. Some trips pass through without stopping at all, which is the thing to check before you pay.
Is it good for snorkelling?
Better than the Blue Lagoon on a busy day. Deeper, clearer, and far fewer people stirring it up. Bring your own mask, because a short stop is no time to be sorting out borrowed gear.
Is it suitable for children?
Not really. There is no shallow water, no beach and nowhere to stand. Confident swimmers only, and the Blue Lagoon is the better choice with a family.
