The site features a sharp drop from the shore, with depths ranging from 3 to 50 metres.

Divers should be prepared for cold water temperatures and variable visibility between 3 and 20 metres. Entry is via the shore. Hazards include cold water, low visibility, and potential entanglement from discarded fishing line. A dive knife or line cutter is essential equipment for all divers at this location.
