Bikini Atoll is the ultimate wreck dive destination — a fleet of warships sunk by nuclear weapons testing in 1946, now resting in crystal-clear lagoon water. The USS Saratoga (aircraft carrier) and HIJMS Nagato (Japanese battleship) are the highlights. Access is extremely limited and expensive, but the historical significance and diving conditions are unmatched.

Honest reality check

What your dive shop won't tell you

The minimum certification printed on a brochure is the legal floor, not the honest recommendation. Here's what we actually think you should bring to this site.

Recommended logged dives

60+

Below this we'd send you somewhere easier first.

Recommended certification

Advanced Open Water

“Most historically significant wreck diving on earth. Aircraft carriers sunk by nuclear bombs. Tec diving's Holy Grail.”

What will challenge you

→Moderate currents. Expect to drift — this is not a skill-builder site for a first trip after certification.
→Recreational limit of 40 m is reachable here (max depth 55 m). Gas planning and NDL tracking matter.
→Wreck penetration requires Wreck specialty training at minimum, and often decompression planning. Don't improvise inside.
→Nearest hyperbaric chamber is ~500 km away. Evacuation is slow. Dive conservative profiles and get DAN insurance before you fly.
→Technical only — 50-60m, trimix, mandatory deco. Remote atoll, zero medical infrastructure.

Photography brief

Subjects are only half the shot. A perfect macro site is useless in a three-knot drift, and a wide-angle dream is useless at 35 m with a murky ceiling. These are the conditions, not the hype.
