Malta Caves: Discover Għar Dalam, Blue Grotto and Gozo

Malta has plenty to reveal below the surface.

Some caves take you back into prehistory, where excavations have uncovered traces of animals and people who inhabited the islands thousands of years ago. Others are best approached from the sea, where sunlight, clear Mediterranean water and limestone walls create an entirely different experience.

Then there is Gozo, where caves hide beneath private homes, stalactites and stalagmites have formed underground and viewpoints open over the red sands of Ramla Bay.

Exploring the Malta caves is therefore about much more than heading underground. Depending on where you go, a day of cave exploring can involve archaeology, a boat ride, snorkelling or a ferry crossing to Malta’s sister island.

No two caves offer quite the same experience. Għar Dalam takes you into Malta’s prehistoric past, while Blue Grotto and Għar Lapsi are shaped by the relationship between limestone and sea.

Għar Dalam translates as the ‘Cave of Darkness’, an appropriate name for one of Malta’s most important prehistoric sites.

Excavations inside the cave uncovered animal bones and human remains, including evidence of dwarf elephants and hippopotami. Walking into Għar Dalam is therefore not simply about seeing a natural cave. It is an opportunity to encounter evidence of a Malta that looked very different from the islands we know today.

For visitors interested in archaeology and history, it is one of the most significant underground caves in Malta to include in an itinerary.

The experience is quite different from Malta’s coastal caves. There is no turquoise sea or swimming here. The appeal lies in imagining the layers of history beneath your feet.

Blue Grotto is one of Malta’s most recognisable coastal sights, and approaching it from the water is part of the experience.

Located around Wied iż Żurrieq, the grotto is known for remarkably clear water and the marine vegetation visible along its walls. As you approach by sea, the scale of the limestone formations becomes more apparent and the colour of the water changes with the light.

If your idea of the best cave in Malta involves dramatic coastal scenery rather than archaeology, Blue Grotto is an obvious contender.

It also makes a natural addition to a day exploring southern Malta, where the landscape feels noticeably more rugged than the busier towns around the harbours.

Not every cave needs to be admired from a distance.

Close to Wied iż Żurrieq, Għar Lapsi is popular with swimmers and snorkellers who want to experience Malta’s clear water at closer range. The small cave and rocky surroundings give the area a more intimate feel than the grand scale of Blue Grotto.

For visitors interested in a sea cave in Malta, Għar Lapsi offers the chance to combine exploration with time in the water.

Summer weekends can be busy, so an early start is worthwhile if you would prefer a little more space. Pack swimming gear and sun protection and be prepared for a rocky rather than sandy coastal setting.

Crossing to Gozo changes the character of the experience again.

In Xagħra, Ninu’s Cave is reached through a private family home. That unusual entrance is part of its charm. Rather than arriving at a large visitor attraction, you descend into a cave known for its natural underground formations.

Nearby, Xerri’s Grotto is particularly noted for its stalactites and stalagmites, formed slowly over time as mineral rich water passed through the limestone.

These caves in Gozo offer a more intimate underground experience than Malta’s sea caves.

Then there is Calypso’s Cave, associated with views over Ramla Bay and its unmistakable red orange sand. Pairing the cave area with time at Ramla gives you a day that combines Gozo’s landscape with one of its best known beaches.

Comino adds a maritime dimension to cave exploring.

Unlike Għar Dalam or the caves around Xagħra, exploring a Comino cave is naturally connected with being out on the water. For visitors already planning a day around Comino, its caves can add another element to the familiar combination of swimming and clear Mediterranean sea.

The information supplied for this article does not identify individual caves in Comino or specify which are currently accessible to visitors. For that reason, anyone planning to explore them should confirm the route and access arrangements with their chosen boat operator.

Sea conditions matter too. A cave that is approachable in calm weather may not be suitable when the water is rough.

If history is what draws you underground, start with Għar Dalam. It gives the visit a clear archaeological dimension rather than being simply a scenic stop.
For sea views and dramatic limestone scenery, Blue Grotto is the stronger choice. Għar Lapsi suits visitors who would rather put on a mask and get into the water.

Gozo is worth the journey if stalactites, stalagmites and smaller underground spaces appeal to you, while Malta’s catacombs and Hypogeum suit travellers who are more interested in the islands’ cultural history.

There is no need to choose just one. The appeal of the Malta caves lies in how different they are from one another.

What you bring depends very much on the cave.

For Għar Lapsi, swimming gear and sun protection make sense. For underground sites, comfortable footwear is more useful. If your cave experience involves a boat, check the sea conditions and excursion arrangements beforehand.

Families should also consider the nature of each site rather than assuming every cave offers the same accessibility. Underground passages, steps and rocky coastal areas can feel very different with younger children.

Guests staying at Rosselli AX Privilege in Valletta or AX The Palace and AX The Victoria Hotel in Sliema can comfortably dedicate a day to exploring southern Malta, combining cave experiences with other attractions around that part of the island.

If Gozo is the priority, guests staying at AX ODYCY in Qawra are based in northern Malta, making it a practical starting point for a day heading towards Malta’s sister island.
