Boat-access Apra Harbor drift with blue coral
Boat-only harbor drift; use a local skipper and stay alert for transiting boats.
Ron’s Reef is a boat-access Apra Harbor drift dive that starts near the harbor and runs west into clearer water. It’s known for blue coral in the shallows, a wide mix of fish and occasional pelagics, and it rewards divers who are comfortable managing current and boat traffic overhead. Go with a local boat operator and treat it as a drift, not a casual shore hop.
