Dolphin Point is Hayman Island's big-fish site. 100 Magic Miles describes rugged terrain of coral outcrops and huge boulders – rock slabs the size of houses – on a sloping seabed from 5 to 18 m, with trevally, mackerel, barracuda and occasional sharks. Texas T Charters adds white-tip reef sharks, hammerheads and tuna to the list, and notes large coral bommies among the boulders, with abundant big marine life year-round. The point's position at the north-western corner of Hayman exposes it to tidal streams running through the channels between Hayman, Hook and the outer islands, and that water movement brings the pelagics.

The boulders create a landscape of gaps, overhangs and passages where fish shelter from the current, and coral grows on their upper surfaces. It is not a snorkelling site – too deep – and it is not a beginner dive when the current runs. 100 Magic Miles notes it is relatively deep with potential currents, so divers should be comfortable drifting and ascending with an SMB if needed. On a slack tide with good visibility, though, it is one of the most exciting fringing-reef dives in the Whitsundays.

Dolphin Point is visited less often than nearby Blue Pearl Bay, and mainly by dive boats with certified divers. The effect of Cyclone Debbie on its coral is not specifically documented, but the boulder topography is unaffected. It is in the Great Barrier Reef Marine Park; confirm zoning before fishing.

A dive here pairs naturally with an easy second dive in sheltered Blue Pearl Bay a short distance south, giving a day that combines current-fed pelagic action with relaxed coral-garden diving.

Boat only. Hayman Island's north-west coast is about 20–24 nautical miles from Airlie Beach – roughly 45–70 minutes by fast day boat from Coral Sea Marina or Port of Airlie, or about 1 hour from Hamilton Island marina. Day tours that stop here include Ocean Rafting, Red Cat Adventures (Thundercat), Whitsunday Dive Adventures and Explore Group (from Airlie and Hamilton Island); overnight sailing and bareboat charters also visit.

Private and bareboat skippers must use the public moorings (time-limited, first come first served) and observe no-anchoring areas marked by reef protection markers; bareboat operators restrict where hirers may go. Parking at Airlie is available near Coral Sea Marina and the Port of Airlie.

The northern Hook Island bays face north and are sheltered from the dominant south-east trades (15–25 knots April–September), but they are open to northerly winds and swell (common October–March) and to very strong south-easterlies that wrap around the headlands. Tidal currents through the islands are strong on spring tides (tidal range up to about 4 m) and can make points and bay entrances difficult – plan dives at slack water and neap tides where possible. Visibility is usually 5–15 m, dropping after strong winds, big tides and wet-season rain.

Manta rays visit May–September. Marine stinger season (box jellyfish and Irukandji) runs roughly November to May – wear a full-length stinger suit or wetsuit with hood and gloves, carry vinegar. Cyclone season November–April; tropical lows and cyclones can close sites and damage coral (TC Yasi 2011, TC Debbie 2017).

Severe Tropical Cyclone Debbie (March 2017) badly damaged the fringing reefs of northern Hook and Hayman islands; recovery is ongoing. The point is relatively deep and prone to current.

Descend among the boulders at 12–18 m, work along the point with the current exploring gaps between the slabs, watch the blue for pelagics, then ascend over the coral outcrops to 5 m.
