Key Dive Site Facts
Dive Site Overview
Descending into the Blue Hole offers an unforgettable start to exploring Gozo’s underwater geology. Divers begin from a shallow shelf inside the circular rock formation, a protected pool about 10 meters (33 ft) wide.
An iconic rectangular archway, richly covered in golden cup coral, leads from the hole into the open sea, typically found between 8 to 14 meters (26 to 46 ft) deep. Beyond this arch, the dive continues towards the large boulders that were once part of the majestic Azure Window, with depths in this area ranging between 5 and 16 meters (16 and 52 ft). Recreational divers can comfortably navigate these shallower sections, while more advanced routes can take you deeper.
The maximum reported depth for diving here reaches around 25 to 45 meters (82 to 148 ft), extending into surrounding cave and wall features.
