Blue Hole

written in collaboration with quatorze (1 spots)

Gozo’s Blue Hole is one of the most famous diving spots in Malta Islands. This round blue hole about 15 meters wide seems carved into the surrounding rocks, but an underwater arch located 10 meters below the surface actually connects it to the open sea. This geological formation is unique and freedivers love to dive here, but it is not a place for snorkeling. Instead, head to the nearby rocky point called “coral gardens” and you will swim amongst many fish, over a multi-leveled rocky seabed. Over the water, the gorgeous Azure Window (natural sea arch) is standing at a distance. Altogether, this spot is a must-do on your Malta snorkeling list.
How to get there?

Blue Hole is located close to the hamlet of Dwejra, on Gozo Island’s west coast (Gozo being the second largest island in Malta archipelago). Follow Azure Window and Inland Sea signs, park on the lot when the road dead-ends. If you’re not driving, a bus line also spots here. A rough path carved into stone leads down to the sea where you will enter the water.

Water entrance

This site has a water entrance area leading straight to the Coral Gardens. Be cautious when getting in the water: rocks are sharp and sea urchins cover them.

Aerial view


The Coral Gardens are a small rocky protrusion a few dozens of meters wide located close to the Blue Hole. Water Depth ranges from 1 to 10 meters, depending on the underwater rock level you’re over. The seabed itself if very rough: several plateaus, breaks and even small canyons compose it.

Sea life is abundant here. You will find yourself in the company of damselfish and thicklip grey mulets from the start. The rocky areas covered with seaweed attract wrasses in numbers: you will spot groups of several dozens. They might be the most colorful species to spot here: look for male ornate wrasses with gorgeous blue and green scales. In addition to all of the above, you will most probably spot starfishes, sea urchins and jellyfishes. Only freedivers will be able to spot species living on greater depth like morays, small groupers or Mediterranean parrotfish.

This spot is not sheltered from the open sea: don’t enter the water when it swells, even lightly. During October and November underwater visibility is at its best, but you will need a wetsuit to stand cold water.

The gorgeous Blue Hole and its underwater arch are for scuba divers and freedivers only. You might be tempted to freedive here: don’t practice apnea without a specific formation and training.

Restaurants and accommodation

Gozo Island is calmer and wilder than Malta, and you can enjoy a peaceful stay here. There are numerous rental options on the island, suiting all budgets. You will have no trouble eating on site: several restaurants have settled around the parking lot.
