Gozo’s Blue Hole is a unique geological formation, making it one of the island’s most sought-after diving spots. Learn everything about it here!

Malta is famous worldwide for being a divers’ paradise, and it is easy to understand why, with so many fantastic spots to explore an abundance of sea life. But, have you heard about Gozo’s famous Blue Hole? Or seen those unforgettable images of the iridescent waters shimmering under the warm sun?  If you love anything remotely subaquatic, it should definitely be on the top of your agenda during your holidays in Malta. Let us tell you a little more about this marine mecca!

What is the Blue Hole?

Blue Hole Gozo

Gozo’s iconic Blue Hole is a natural rock formation resembling an upright tube that has been carved out by thousands of years of wind and wave power. At first glance, this natural wonder may seem carved into the surrounding rocks. However, an underwater arch located 10 metres below the surface actually links it to the open sea, making it a unique geological formation.

To reach the Blue Hole, you need to walk over ancient coralline limestone rocks, consisting of rough surfaces and some sharp edges. From the shore, a shallow-water shelf leads out to a sudden drop that is the Blue Hole. It offers a sheltered entry for this dive which takes you through a large archway starting at 6m and stretching right down to the bottom at 15m. 

A large cave at the bottom of the hole is also worth exploring. Some spectacular scenery awaits you at the back of the cave, which is why this area is considered as one of the most sought-after dive sites in the Maltese islands.

How to get there?

The Blue Hole is situated close to the hamlet of Dwejra, on Gozo’s West coast. If you’re driving, simply follow the signs to the former Azure Window and Inland Sea and park where the road comes to a natural end. If not, fret not as a frequent bus also stops here. A rocky path carved in cliffs leads down to the sea where you will enter the water.

How about the Coral Gardens?

The Coral Gardens are a small rocky protrusion, a few dozens of meters wide, located very close to the Blue Hole. Once again, take extra care when getting in the water as the surrounding rocks are very sharp and sea urchins cover them. Water depth here ranges from 1 to 10 meters, depending on the underwater rock level you’re over. The seabed itself is very uneven: several plateaus, breaks and even small canyons compose it, make sure you wear sea shoes so that you won’t be worried about your feet!


Once you are safely in the Coral Gardens, you will get a real sense of just how incredible nature is. An abundance of extraordinary sea life will envelop you, including damselfish and thick lip grey mullets. What’s more, the rocky areas covered with seaweed attract wrasses in numbers- take a Go Pro, it’s easy to spot large groups of them to snap! They may be the most colourful species to spot here: look for ornate male wrasses with gorgeous blue and green scales. In addition to the above, look out for starfish, sea urchins and jellyfish!

Precautions to take

Gozo Scuba Diving

The Blue Hole and Coral Gardens are not sheltered from the open sea: don’t be tempted to enter the water when it swells, even a little as things can change quickly. During October and November, underwater visibility is at its clearest, though you will need a wetsuit to withstand the cold water. The gorgeous Blue Hole and its underwater arch are for scuba divers and free-divers only, not for snorkellers. If you’re a snorkeller, head to the Coral Gardens instead!
