The Boulders is a compact, accessible wall dive just northwest of Norah Head's well-known Bull Rocks bombora, close enough to the boat ramp to make it an easy first or second dive of the day. The wall runs north-west to south-east with its top at about 17 m and its base just over 21 m, and true to its name the site is scattered with hundreds of boulders ranging from table-sized to as large as a small room, creating a broken, textured profile rather than a smooth rock face. A mooring exists at the site, though it has been reported non-functional at times, so a shot line or careful anchoring is a sensible backup.Marine life here leans toward schooling species and characterful residents rather than big pelagics: one-spot pullers school in large numbers, joined by silver sweep, yellowtail, bream and luderick, while eastern blue devilfish and giant cuttlefish are notable, photogenic finds among the boulders.

Gorgonias, sea squirts and sponges dress the rock surfaces throughout. Being only about two hours from Sydney by road and a short boat run from the ramp, The Boulders is often worked into an easy day-trip itinerary alongside its neighbour The Bull, giving visiting divers two contrasting boulder-field dives — one on a defined wall, one on a rising bombora — within a few minutes' boat ride of each other. It's a good option for divers stepping up from shallow reef work into slightly deeper, more current-affected diving without committing to the area's genuinely deep wrecks and canyons.

Launch from the Norah Head beach boat ramp and run a little over a kilometre offshore to the northwest of The Bull/Bull Rocks bombora; a short, easy run suited to most conditions that allow launching in the first place.

Boats launch straight across the beach into open ocean from Norah Head's rough boat ramp, so any meaningful swell or onshore wind makes launching and retrieving the boat difficult or impossible — this restricts trips to smaller, lighter craft and calm-to-moderate conditions. Once at sea, the offshore reefs are exposed to swell from the north-east through south-east; look for a period of light winds and under 1.5 m swell. Visibility is best after several settled days and noticeably improves when the East Australian Current pushes warmer, clearer water down the coast; a cold-water upwelling or recent blow brings green, sediment-laden water instead.

Anchor or shot onto the wall around 17-19 m, follow the boulder-strewn wall along its north-west to south-east line, working among the table- and room-sized boulders for eastern blue devilfish and giant cuttlefish, before ascending for a safety stop.

Norah Head Divers Depot runs boat charters to the offshore reefs from the Norah Head boat ramp; Terrigal Underwater Group club members also dive these sites regularly from private boats.
