Scuba diving in Bikini Atoll, Marshall Islands

Bikini Atoll is the world’s most storied wreck fleet: the nuclear test ships of Operation Crossroads, headlined by the aircraft carrier USS Saratoga and the Japanese battleship HIJMS Nagato, resting in the lagoon of a remote Marshall Islands atoll. It is an expedition-grade, deep, decompression-oriented destination reached by liveaboard or the atoll’s small land-based dive operation, and sharks patrol the passes.

How condition context works

Common questions about diving in Bikini Atoll, Marshall Islands

How do you dive Bikini Atoll?

By expedition: liveaboard itineraries and a small land-based operation run seasonal trips to the atoll, which is remote even by Pacific standards. Space is limited and books out far ahead — plan around the operators’ published seasons and confirm logistics directly with them.

How deep are the Bikini Atoll wrecks?

Deep. The Crossroads fleet rests at depths that make this a decompression-oriented, technical-leaning destination, and operators typically expect advanced or technical certification with substantial logged experience. Confirm each operator’s exact requirements — they publish them clearly.

Is Bikini Atoll safe to visit given the nuclear history?

Dive operators have run trips there for years under Marshall Islands oversight, with visits structured around the current guidance for the atoll. For radiological specifics, rely on the operators and official Marshall Islands information rather than a dive-planning site — and note that PickADive never certifies safety of any kind.

Can PickADive tell me if conditions are safe today at Bikini Atoll?

No. PickADive helps with destination research and trip planning context for Bikini Atoll, but it does not certify that a dive is safe today. Follow your operator’s briefings, training limits, and the expedition’s rules.
