|Calypso Tunnel, otherwise known as Triple Arch Reef, is found approximately 100m offshore northeast of Xwejni Bay, due north of Marsalforn tower on Gozo’s north coast.|
|This dive starts along the edge of a reef which is an underwater extension of the headland above. Following the drop-off, divers will notice two narrow horizontal cracks at 21m and another one below it at 32m, through which divers can easily pass finding themselves in a large cave.
The roof of this spectacular cavern has collapsed in two places, forming two enormous holes, the largest of which is 30m long. The narrow bridge between these 2 holes gives the illusion of a natural, massive, spectacular archway. Thus the name Triple Arch Reef.
Therefore, contrary to its given names, this unique underwater feature is neither a tunnel nor a natural archway.
Turning back to look towards the north facing wall of Calypso Tunnel, divers will see the two narrow horizontal cracks at 21m and the other large archway below them at 32m. We call this wall The Face because of the striking resemblance with its two ‘eyes’ and big ‘mouth’.
|The best spot to see this ‘Face’ would be at a depth of 19 metres, right under the ‘archway’.
Divers can easily dive through the left eye and obviously through the north arch and the two holes at roof level. The depth of the plateau above this cavern is 16m while the deepest part is 34m at the mouth.
Towards the west, along the drop-off and not far away from Calypso Tunnel, there is a large cave (approximately 15 minutes diving distance). This cave is known as Submarine Cave. The cave entrance starts at 21 metres and the silty bottom is 34 metres deep. Actually, this cave is closer to Double Arch Reef, which is located further west along the same wall.
