The Cirkewwa Arch is actually a cavern which has long since collapsed, leaving this spectacular arch as a result. The arch stands just before the drop-off at a depth of 18 meters, rising up to 7 meters below the surface. Divers often start at the protective reef nearby, which is full of algae and posidonia. You can see pelagic species such as skipjacks, amberjacks and barracuda often at this site.
You can also combine the Arch with the dive on the Tugboat Rozi
