Dive Spot Guide•
Skimin’s Reef
Skimin's Reef is a long Oahu ledge dive with arches and reef fish.
Drift-style south Oahu reef dive with a ledge, arches, and strong fish life; best handled through an operator rather than as a casual shore dive.
About Skimin’s Reef
Skimin's Reef is a long south Oahu ledge off Diamond Head with arches, a shallow top, and a deeper outer wall. Dense coral and schooling reef fish cover the reef top, while pufferfish hide in shaded cuts and larger animals may pass in the blue. It is best treated as a drift-style boat dive, so current, swell, and timing matter more than a casual shore plan.
