Bikini Atoll Diving — Marshall Islands
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.

Safety & Emergency
Dive Insurance
Dive insurance is essential. Standard travel insurance often excludes scuba diving. We recommend DAN (Divers Alert Network) for comprehensive dive accident coverage.

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.
Below this we'd send you somewhere easier first.
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.
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.
Recommended kit
- →Dedicated video light for dark wreck interiors; don't rely on strobes alone
What this site will teach you
The dives that made you a better diver are the ones that made you uncomfortable for the right reasons. Here's what this site will quietly train you for.
Wreck penetration fundamentals
advancedLine laying, gas planning for the way back, and silt-out response. Learn it on a site with clear-water wrecks before you try it in darker water.
Deep profile discipline
technicalMax depth 55 m puts you at the edge of recreational limits. You'll build NDL tracking instincts, gas reserve management, and safety-stop discipline you can't get on 18 m reef dives.
