Stonehenge, at the northern most tip of Island number four is a relatively deep site. Gigantic underwater rock formations, towering upwards have created underwater valleys and ravines, drizzled with huge Gorgonian Fans and sponges. Currents can sometimes be quite strong here bringing in larger pelagics. Schooling Jacks, Trevally and Barracuda are a common site. The rock formations are what give this dive site it's name and in good visibility, it's truly awesome.
