Sherwood Forest
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 — treat everything here as planning ranges.
Sherwood Forest takes its name literally: stands of green tree coral rise off the deep ledge like a plantation, sheltering sweepers and juvenile fish in their branches. It is a quieter, moodier dive than the manta circuit — the pleasure is the habitat itself, worked slowly with a torch: leaf fish and scorpionfish in the coral trees, nudibranchs on the rubble, morays and lobster under the shelf. The deep sand alongside stays worth watching; smalleye and marbled rays commute past, and mantas appear often enough to keep heads on swivels. Depth caps the visit at half an hour of concentration.
The moment you come for: Green tree coral groves; slow-lane macro at depth with big-ray flybys
Topography: Deep reef named for its stands of green tree coral rising from the ledge
Current: Deep offshore ledge; conditions swing with swell and the along-coast flow.
Know before you splash
Hazards: Depth and short no-deco windows; occasional strong surface chop for the launch home.
Conservation: Tree corals snap under careless fins — keep clearance generous.
Nitrox: Worth it here — profiles sit in the range where enriched air meaningfully extends no-stop time (with the training to use it).
