Mackerel Bay lies on the sheltered eastern side of Hook Island, the second-largest island in the Whitsundays. Its reef is shaped into two protected keyholes divided by a coral wall, where vibrant soft corals, hard corals, and fan corals carpet nearly every surface. The bay is famous for its teeming fish life — anemonefish (clownfish) dart among their host anemones, parrotfish crunch audibly on coral, and schools of butterflyfish, angelfish, and sergeant majors swirl overhead. Green sea turtles are a near-guaranteed sight, often napping on 'Turtle Sleeping Rock' at the southern keyhole entrance, while stingrays forage in the shallows and giant clams display brilliant mantle patterns. The reef wall drops steeply to 5–8 m, offering excellent snorkeling for all levels.

Low risk: Moderate currents
Moderate currents can occur in the bay even when surface conditions appear calm, particularly around the reef edges and keyhole entrances.
Low risk: Variable visibility
Underwater visibility is highly variable in the Whitsundays and can be poor due to wind, tide, or recent rain, sometimes spoiling the snorkeling experience.
Low risk: Sharp coral rubble
The reef is recovering from Cyclone Debbie (2017) — some areas remain dead coral with sharp, unstable substrate. Snorkelers should avoid touching the reef.
