How to get there

Situated close to the hamlet of Dwejra on Gozo’s west coast, the Blue Hole can be reached by following the signs that will lead you to the now collapsed Azure Window and Inland Sea. If you are heading towards the dive site with your own transport, you may park in the parking lot. Alternatively, we may provide you with transport to and from the diving location. A rocky path carved in the cliffs leads down to the sea from where you can enter the water.

Explore the Blue Hole

Also known as the Blue Cave, Gozo’s Blue Hole is one of the most famous diving spots in the Maltese Islands and a must for any freediver. Known for its circular formation carved after centuries of wind and waves have been crashing on to it and its iridescent waters, at first glance, the site seems as if it’s carved into the surrounding rocks. Although a sinkhole in the limestone of about 10 metres wide and five metres across, the hole is indeed a sheltered pool since it is protected by a fringe of rock, however, an underwater arch located 10 metres below the surface leads to the open sea. At the very bottom of the hole you’ll find a large cave worth exploring.

What to look out for

One popular attraction you mustn’t miss is the Coral Gardens. Situated near the Blue Hole, these consist of small rocky protrusions, a few dozens meters wide. The seabed itself can be quite rough with plateaus, breaks and even small canyons and depending on the underwater rock level, water depth can range anywhere between one to 10 metres. Expect to spot a number of fish like morays, small groupers, Mediterranean parrotfish, damselfish and thick lip grey mullets. Other extraordinary sea life you’re bound to come across include starfish, fireworms, sea urchins and jellyfish.

The walls of the archway itself are covered with colourful coral tubeworms, sponges and other small marine life. On the surface, you’ll find quite a few large boulders dotting the area.

How to dive this site

Once you have walked through the ancient coralline limestone rocks from the shore, a shallow water shelf leads out to a sudden drop that is the Blue Hole. This offers a sheltered entry which takes you through a large archway starting off at 6 metres which eventually stretches right down to the bottom at 15 metres.

Once you have passed the arch, you may swim through the tunnel and explore the superb marine life. Then, you may head towards the reef and swim through the large vertical crack which is the so-called Chimney, starting at 18 metres and swim along all the way to the Coral Garden. From then onwards, you may either swim out to the open sea or turn back and visit the cave situated at the far end of the Blue Hole.

About San Lawrenz

Built on a plain surrounded by the hills Ghammar, Gelmus and Ta’ Dbiegi, San Lawrenz is one of the least populated villages on the island of Gozo and has managed to retain much of its traditional and rural lifestyle. The village has taken its name from Lawrence of Rome, who is also the village’s patron saint.

Mainly known for the bay of Dwejra, located in the limits of San Lawrenz, the Dwejra Inland Sea and Tunnel is another excellent diving site found nearby the Blue Hole. On the hand, if you would like to explore this part of the island on land, walk along the coast and visit the prominent Fungus Rock and the site where the Azure Window was once the area’s main landmark.

Frequently Asked Questions

  • Which wind direction is best to freedive this site?

    Because of the closed nature of the Blue Hole, light to moderate winds from North-west to South-west are fine but becomes difficult when the wind picks up. Generally, any other wind direction and strength is fine to dive the Blue Hole. This is another favourite location of Deep Med for our beginner courses.

  • What are the best times do dive this site?

    During the summer months it is usually packed with tourists and SCUBA divers. Early morning hours or sunset time is recommended. If you’d like to enjoy the dive site all by yourself, visit during low season and book in a coaching session.

  • How accessible is the dive site?

    Whilst the dive is accessible by foot, there are small boulders and finishes off with sharp rocks where you have to balance. Take it slowly and preferably take some kind of water proof shoe with you.

  • Is there any boat traffic?

    There is no boat traffic both during the high and low season months.
