A true vertical wall, full of overhangs and fissures, with lots of swimthroughs and cavelets. Towards the Blue Hole, in the south, the reef profile softens to a steep slope. 

The dive begins in a small slot in the reef table, around 100m (328ft) north of the Blue Hole lagoon; after reaching your maximum depth on the sheer wall section just south of the entry, ascend slowly and follow the reef south to the lip of the Blue Hole lagoon, in about 6m (20ft) at the top of the reef. This is your exit point. 

Coral cover on the wall section is not abundant, but there is quite good growth of plate and cabbage coral as well as black coral bushes and white soft corals. 

Although the fish life here is reasonable, there are many sites with greater diversity and larger populations. 

Like all wall sites, this one should be treated with caution; it is easy to be seduced by the sheer profile and far exceed your planned maximum depth. You should also remember that the exit point is only a few hundred meters from the entry, and is easily missed.
