Three Sisters
Depth is the range from the top of the site to its usual maximum; "recommended cert" is the mainstream-agency level operators usually ask for, not a legal rule. Currents and visibility change daily, so treat everything here as planning ranges.
Three rocky outcrops stand close enough together to dive as a single wandering circuit, and the gaps between them do the interesting work: sand gullies where stingrays and zebra sharks settle, coral saddles where morays share holes in twos and threes, and current-brushed corners that gather snapper into loose silver weather. Soft coral colors the shaded faces of each sister, turtles commute between them, and the layout rewards navigation-minded divers who like a dive with chapters. Operators report the reserve's occasional oddities here - a passing mola has entered local legend - but the dependable pleasure is simpler: three small reefs' worth of life in one unhurried hour, with depth options for everyone in the boat.
The moment you come for: Ray-and-shark sand gullies between the outcrops; a naturally structured circuit; soft-coral faces in the shade.
Topography: Three adjacent rock outcrops linked by coral gardens and sand gullies
Entry: A cluster of rocky outcrops within the reserve dived as one circuit; conditions decide which of the three gets the attention.
Know before you splash
Hazards: Mild current in the saddles; keeping the circuit's geography straight is the main challenge.
Permits & rules: Environment Authority entry permit required, arranged by licensed operators.

"Charted here" species were listed by our editors from the sources on this page. Counts are GBIF occurrence records: observations logged within about 5 km of the charted position since 1990, matched only against the species in our catalogue. They show what has been seen there, not a promise of what you will see.
