The summit, at 25 meters, is reached through free water down a line. It provides a home and a hunting ground for a plethora of marine life. Shoals of mackerel and tuna hang around in the blue, with visits from grey sharks and reef sharks. Turtles appear on occasions, but there is always a frog fish or two sitting around on a coral. Remarkably large lionfish glide along the path ways in the coral adding an Elizabethan touch to the scene with their extravagant fins.

Sunken Island for experienced divers only. Due to the tides, a strong current is often present.
