It is named after the Kabak Bay in the region. Only suitable for experienced divers. In fact, this place is not a cave, but a tunnel rather with 60 meters in length, 5-20 meters in width, and 5-8 meters in height. In the tunnel there are extremely fragile corals (byrzooa pyrzooa), which are a kind of moss which should not be touched. The inhabitants of the cave are a few rocklings and cave shrimps. After leaving the tunnel, at 11-12 meters depth, there is an aircraft engine with no record and information about it.
