On the western side of Reqqa Point, Bottleneck Cave drops down through the reef from 37m to 58m. The entrance hole at 37m, just large enough for a diver to swim through, soon takes the shape of a vertical cylinder about 5m in diameter. Along the walls of this cave are numerous cracks inhabited by various types of shrimp. At the deep end of the slightly sloping, sandy floor there is a narrow tunnel spectacularly leading out of the chimney to the bottom of the cliff. Looking up from this depth towards Reqqa Point is breathtaking. Because of the depth and condition of this chimney, this dive should be attempted by very experienced divers only.
