The first, smaller archway starts at 27 m and directly beneath it is the larger of the two, stretching to the seabed at 36 m. There is prolific fish life here especially around the outer leg of the reef, with groupers and spectacular shoals of barracuda dominating.
Double Arch Reef
This extended underwater rocky headland lies approximately 200 m offshore. Two large archways have been naturally carved through it, creating one of the strangest and most impressive formations to be found in Maltese waters.
