Why dive here
With 79+ marine species recorded in the area - including blue sharks, dolphins, hammerhead sharks, humpback whales and orcas - Canyon offers some of Poor Knights Islands's richest reef diving. Water ranges 15-22°C, warmest January, February, March.
Canyon, for us, is one of those Poor Knights dives where you genuinely feel like you're exploring. You drop down onto a sheer wall, thick with kelp fronds swaying in the surge, and then it just… keeps going. The canyon itself, a narrow cut in the rock, drops deeper than the 18m advertised max, so if you're comfortable watching your depth, you can duck into the shadows where the wall overhangs really start to feel like a roof. We’ve spent ages here, finning slowly, letting our eyes adjust to the dimmer light. It’s where you often spot the bigger, shyer fish, like giant boarfish hovering in the gloom or perhaps a southern eagle ray gliding past. Pink maomao often school here, a flash of colour against the dark rock. Keep an eye on the smaller stuff too; the walls are a mosaic of encrusting sponges and nudibranchs, and we've even seen brown dogfish tucked away. It's a dive that rewards patience and a good torch, making it a solid pick for divers who enjoy a bit of atmospheric exploration rather than just big schools in the open.
