North Horn
Why dive here
With 154+ marine species recorded in the area - including hammerhead sharks, sea turtles, tiger sharks and napoleon wrasse - North Horn offers some of Great Barrier Reef's richest reef diving. Water ranges 24-30°C, warmest January, February, March.
North Horn is where the Cod Hole plateaus into deeper water. Here, we often find a gathering of pelagics: grey reef sharks, the occasional silvertip, and schools of barracuda or trevally. It’s a drift often, so we'd recommend it for divers comfortable with current, looking for bigger fish action. Best dived as a second or third dive to give the sharks some space.
