Sunken ships, a WWII fighter plane, and turtle-covered reefs — all minutes from Waikiki. Oahu is Hawaii's wreck-diving capital. Here are the top-rated Oahu dive shops and the sites they'll take you to.
What's the best diving on Oahu, and who do I book with?
Oahu is Hawaii's wreck-diving capital. The signature site is the Sea Tiger, a 150-plus-foot ship and one of Hawaii's deepest popular recreational wrecks, with its deck around 60 to 90 feet. The YO-257 and neighboring San Pedro are paired artificial-reef wrecks full of turtles and reef sharks, and the Corsair is a WWII fighter plane resting deeper for advanced divers. Most Oahu dive shops launch from Kewalo Basin, just 10 to 15 minutes from Waikiki, run small groups, and offer reef dives, wreck dives, and full certification courses.
Oahu's diving has a personality all its own. While other islands lead with reefs and big animals, Oahu is about wrecks — a south-shore graveyard of ships and a sunken warplane, most of them placed as artificial reefs and now draped in coral and crowded with life. For wreck divers and history buffs, no Hawaiian island compares.
The convenience is unbeatable, too. Boats leave from Kewalo Basin just minutes from Waikiki, so you can dive a 150-foot ship in the morning and be back at the beach by lunch. The wrecks suit a range of levels, from accessible multi-level dives to deep advanced profiles, and the reefs between them brim with turtles and rays.
This guide covers the best Oahu dive sites and the operators who run them. For the island's full site list, see our Oahu dive sites guide, and compare operators statewide on our main Hawaii dive shops hub.
Most Oahu diving happens along the south shore, a short boat ride from Kewalo Basin with Diamond Head and the Honolulu skyline as your backdrop. Operators usually pair a deep wreck with a shallower reef on a two-tank trip.
The Sea Tiger is Oahu's flagship wreck and one of Hawaii's deepest popular recreational dives. A former Chinese trading vessel over 150 feet long, it was sunk in 1999 and now sits remarkably intact. The deck and superstructure run roughly 60 to 90 feet, with the sand bottom near 100 to 120 feet, so divers enjoy a good multi-level profile. Swim-throughs and penetration points abound, and the wreck teems with green sea turtles, whitetip reef sharks, eagle rays, moray eels, and schooling fish.
These two wrecks sit close together and are usually dived as a pair. The YO-257, a 175-foot navy oiler sunk in 1989 as part of the state's artificial-reef project, rests upright around 97 to 100 feet, with its deck near 70 to 90 feet and abundant swim-throughs. A short swim away, the San Pedro lies a touch shallower. Both are turtle magnets — the San Pedro's deck even serves as a turtle cleaning station — and whitetip reef sharks often shelter in the structure.
The Corsair is Oahu's only natural wreck: a WWII F4U fighter plane that ditched in the 1940s and now rests around 105 to 115 feet. Because it sits deep with no upper structure, bottom time is short, making it an advanced dive — but eagle rays, octopus, and nudibranchs reward those who go. Between wrecks, operators dive vibrant reefs like Fantasy Reef and the lava-formed Ewa Pinnacles, rich with reef fish and turtles.

Oahu's south shore dives well year-round, but a little planning makes your trip smoother.
The south shore, where the wrecks lie, is most protected in summer, when seas are calmest and visibility is best. Winter can bring south swells occasionally, but the lee of the island usually stays diveable. North Shore sites, by contrast, are a summer-only proposition because of big winter surf. For wreck diving off Waikiki, almost any month works.
Match the wreck to your training. The Sea Tiger's deck and the YO-257 offer multi-level profiles many certified divers can enjoy, while the Corsair and deeper penetration dives call for advanced or wreck certifications. If you want to go deeper or inside the wrecks, ask about specialty courses — several Oahu shops offer them. Honest about your experience, and your guide will place you right.
Book ahead in summer and around holidays. Most operators include tanks and weights; confirm whether full gear rental is extra. Arrive about 30 minutes before departure for check-in, gear fitting, and the briefing.
