Comino Island Guide: Blue Lagoon, Crystal Lagoon & Caves

Comino is the smallest of Malta's three main islands — just 3.5 km², with no permanent population, no cars and only a handful of buildings. What it lacks in size it makes up for in some of the clearest water in the Mediterranean. Here's everything on the island worth seeing, and how to plan a visit by boat.

Where it is

Where Is Comino?

Comino sits between Malta and Gozo, roughly a 20–25 minute boat ride from either. It's part of Malta but functions almost entirely as a nature reserve and day-trip destination — there are no residential towns, just a couple of seasonal facilities near the main swimming spots.

Because there's no bridge and no car ferry, the island stays quiet and undeveloped. Almost everyone arrives on a boat tour or the passenger ferry, spends the day swimming and snorkelling at the lagoons and caves, and heads back the same day.

Other Experiences You Might Enjoy

The trips most visitors pair with a day on Comino.

Want to see both lagoons in one trip? The most popular options pair Comino’s Blue Lagoon and Crystal Lagoon with the Santa Maria sea caves, add a day on Gozo for the Citadel and Dwejra, or swap the crowds for a golden-hour sunset cruise from Sliema, Bugibba or St Paul’s Bay. The live options below update automatically for these Comino, Blue Lagoon and Gozo experiences.

Reachable only by boat

Getting to Comino

No bridge and no car ferry — here are the three ways onto the island.

  1. Boat tours (most common)

    Departing from Sliema, St Julian's, Bugibba and St Paul's Bay in Malta — the most common way to visit, often combined with Gozo and the sea caves. Tours usually stop at several spots around the island rather than just the ferry drop-off point. Based in the north? See our St Paul's Bay & Bugibba boat trips guide.

  2. Passenger ferry

    From Ċirkewwa in Malta or Mġarr on Gozo — cheaper, but with fixed schedules and no vehicle access. It drops you at the Blue Lagoon only, missing the caves and Crystal Lagoon that cruises reach.

  3. Private boat charter

    For a more flexible, less crowded visit — a private charter sets its own timing and route, and can anchor away from the busiest landing points.

On the island

Top Things to See on Comino

Two lagoons, a cluster of sea caves, a Knights-era watchtower and a quieter beach.

The headline

The Blue Lagoon

A shallow bay between Comino and the islet of Cominotto, known for turquoise water over a white sand-and-rock seabed — the most-visited single spot in the whole Maltese archipelago.

The quieter twin

The Crystal Lagoon

On the opposite side of the island — smaller, deeper and framed by cliffs. Quieter than the Blue Lagoon, and popular for cliff jumping and a more peaceful swim.

Boat-only

Santa Maria Caves

A cluster of sea caves near Santa Maria Bay, reachable by boat or on a snorkelling detour. Clear water and dramatic rock formations make this a favourite add-on stop.

Knights-era

Comino Tower (St Mary's)

A 17th-century watchtower built by the Knights of St John, overlooking the Blue Lagoon from the hill above — a short, worthwhile walk if your trip allows time ashore.

Beach alternative

Santa Maria Bay

A quieter beach than the Blue Lagoon, with a more relaxed atmosphere and fewer crowds — useful if the Blue Lagoon feels too busy.

Clear water

Snorkelling spots

Both the Blue Lagoon and the water around the Santa Maria Caves are shallow and clear, with visibility often over 20 metres — some of the best easy snorkelling in Malta.

Blue Lagoon vs Crystal Lagoon: Which to Choose?

Many full-day tours include both — but if you have to pick, here's the split.

CrowdsBusier — the postcard spotQuieter, more peaceful
Good forFamilies and casual swimmersCliff-jumping and a calmer swim
ViewsClassic Malta postcardDramatic cliffs and coves

Short version: choose the Blue Lagoon for the shallow, sandy, family-friendly swim; the Crystal Lagoon for a quieter, deeper cove. Many full-day boat tours include both, so you don't have to choose. Read the full comparison →

When to go

Best Time to Visit Comino

Both lagoons get busy by late morning in summer — timing is everything.

Season

Boat tours typically run from around April/May to October; many pause over winter when the sea is rougher.

Time of day

Arrive early (before 10am) for the calmest water and smallest crowds — both lagoons fill up by late morning in summer.

Peak months

July and August are warmest but busiest, so book boat trips ahead, especially full-day tours combining Gozo.

Shoulder season

May, June and September offer warm water with noticeably fewer visitors — arguably the sweet spot.

The free pass

Since 1 May 2025, stepping onto land at the Blue Lagoon needs a free QR pass; swim from the boat and you won't need one.

Sea conditions

Cave visits and swim stops depend on the weather — captains adjust the route on rough days, so treat the caves as a bonus.

Common questions, answered

Comino Island: Frequently Asked Questions

Does anyone live on Comino?

No — Comino has no permanent residents. It functions as a nature reserve with only a couple of seasonal facilities near the main swimming areas, and no cars or residential towns.

Can you stay overnight on Comino?

There is very limited accommodation on the island, so the vast majority of visitors come as day-trippers by boat from Malta or Gozo and leave the same afternoon or evening.

How do you get between the Blue Lagoon and Crystal Lagoon?

By boat, or on foot via a walking trail across the island. Most boat tours simply reposition the boat between the two, so you rarely need to walk unless you want to.

Is Comino good for snorkelling?

Yes — both the Blue Lagoon and the area around the Santa Maria Caves offer clear, shallow water well-suited to snorkelling, often with visibility over 20 metres away from the busiest boat traffic.

Do I need to book a boat tour to Comino in advance?

In peak summer months, yes — popular departure times to Comino can sell out, especially for full-day tours combining Gozo. In May, June and September you have more flexibility, but booking ahead still secures your preferred time and port.

Is there an entrance fee to visit Comino?

There is no entrance fee for the island itself — you pay only for your boat trip or ferry. Since 1 May 2025, however, stepping onto land at the Blue Lagoon requires a free pre-booked QR pass; swim from the boat and you do not need one.
