Local operator required
Most trips depart from Honolulu Harbor, and a local boat team is the practical way to manage the deep wreck and channel timing.
Boat-only south-shore wreck dive with a deep upside-down hull, strong-tide windows, and the best visibility in calmer summer conditions.
About LCU
LCU is a deep south-shore Oahu wreck dive on an upside-down landing craft that now functions as an artificial reef. The dive is about reading the hull, the rubble plain, and the blocks that have turned into fish habitat rather than chasing big swim-through drama. It is a boat-only site for certified divers who are comfortable with depth and a conservative profile. Pick the day carefully, because tide changes and south swell can make the site feel much bigger than the wreck itself.

Not a freedive site; the depth and wreck profile make scuba the correct use case.
