Boat-dive wall site in the Poor Knights with steep rock and rich marine life.
Serpent Rock is a boat-dive standout in the Poor Knights Marine Reserve, with steep rock faces, a shallower shelf on one side, and outer edges that fall quickly into blue water. The site is known for dense fish life, corals, and dramatic structure that rewards confident buoyancy. Expect a dive that works best when the sea is settled and the crew can place you on the side of the rock that suits the day's conditions.

Key Hazards
Safety Notes
Watch your depth on the outer faces and treat the west-end caves and shafts as overhead features if you venture into them.
Access Restrictions
No landing on the islands or rocks, no tying to the shoreline, and no fishing or taking marine life inside the reserve.
Legal Notes
The Poor Knights are a marine reserve: no fishing, no take, no disturbing marine life, and follow the reserve's boating and anchoring rules.
Community notes to help plan your visit.
Scuba Diving
Best as a confident boat scuba dive with good buoyancy control. Spend time along the wall, then keep an eye on depth as the rock falls away quickly.
Freediving
Not a primary freedive target; the site's main features sit on steep walls and deeper faces.
Snorkeling
Not a primary snorkel target; the better Poor Knights snorkel picks are gentler bays and arches.
