Before Your Trip
The wrecks of Bikini Atoll all lie at depths beyond standard recreational dive limits, with most starting around 50 metres.
As most of the diving in Bikini Atoll will be extended range, there will be a maximum of two (2) technical dives offered on most days.
For safety, there is a mandatory 4-hour surface interval between dives and an afternoon off mid-trip (optional land tour and beach BBQ will be offered instead).
Each diver is responsible for planning their own dive profile with their dive buddy, with the assistance of the Cruise Director who is familiar with diving the wrecks of Bikini Atoll.
Due to the depths of the wrecks in Bikini Atoll the diving is only suitable for divers who have deep, technical diving certification (beyond 50 metres) and with wreck diving experience.
The minimum required certification is TDI Extended Range, PADI Tec 50, or equivalent, with at least 100 logged dives and previous experience with wreck penetration.
Bikini Atoll itineraries are NOT suitable for recreational divers, even those who are certified to 40metres.
Cylinders, Gases and Sofnolime supplies are limited and subject to availability. All requirements MUST be requested in well in advance by completing the Technical Equipment and Gases Requests Form and returning it to our reservations team as early as possible.
The remoteness of the destination means supplies have to be obtained for the whole Bikini season before the vessel leaves Truk Lagoon (or the Solomon Islands) making it difficult to accommodate any requests without at least 3 months notice.
Please inspect and test all your dive equipment before coming to Bikini as there are no dive centres or facilities for repairing equipment in Kwajalein, Bikini or on board. If you have just had your equipment serviced we still recommend you test it thoroughly before travelling.
• We advise all guests to ensure that their vaccinations are up to date. Please make sure you use insect repellent and cover exposed skin to prevent any insect-borne diseases. If you are travelling with medication, please bring your physicians prescription with you.
• Measles immunisation
• The Republic of the Marshall Islands requires travellers born in or after 1957 to show proof of up-to-date measles / MMR vaccination in the form of an official measles immunization card bearing the signature and stamp of a licensed health care provider. Documented laboratory confirmation of immunity or history of measles disease on an immunization card is also considered acceptable to meet the requirement.
• Visa Information
Transit via Guam and Hawai'i: You will need to apply for an ESTA under the Visa Waiver Program or acquire a USA visa prior to travelling.
IMPORTANT: All travellers wishing to enter the US or its territories under the VWP need to hold a passport with an integrated chip (an ePassport).
• A tourist/visitor visa valid for 30 days is issued on arrival for citizens of the EU, UK, Australia, New Zealand and Canada. Citizens of the United States do not require a visa. However, as entry requirements can change at any time, we recommend that guests check with their nearest Marshall Islands embassy or consulate at https://www.embassy-worldwide.com/country/marshall-islands/
• Passport Validity
Your passport should be valid for a minimum period of 6 months beyond the period you intend to stay in the Marshall Islands.
• Airport Taxes
All passengers travelling out of the Marshall Islands are charged a $20 USD departure tax to be paid in cash only.
We recommend that you book your international flight to and from Kwajalein Airport with United Airlines from and to Hawaii. Flights operate 3 times per week, from Honolulu departing early in the morning on Monday, Wednesday and Friday, and takes around 7 hours.
Generally you will need to leave from Los Angeles (LAX) or San Francisco (SFO) the day before (Sunday, Tuesday, Thursday) to make the early connection in Honolulu. Ideally, you should plan to arrive in Honolulu one day in advance of your flight to Kwajalein and book a hotel for the night.
Keep in mind you will be crossing the date line traveling to Kwajalein Atoll so you will arrive the day after departure from Hawaii.
Our Bikini Atoll itineraries are built around the United Airlines flight schedule from Honolulu, Hawaii which serves both Kwajalein and Majuro. Depending on your itinerary, we highly strongly recommend you use this flight to get to and from your embarkation and disembarkation point.
Passengers travelling from the Marshall Islands are required to pay an airport departure tax, for Kwajalein this is currently 20US$. This varies from airport to airport and must be paid in US$ cash.
Our itineraries are based on the United Airlines flight from Honolulu in Hawaii, which departs from Honolulu around 7am
We therefore strongly recommend guests spend an additional night before the start of their liveaboard itinerary to ensure they make the flight connection and are well rested for the diving ahead.
Please be aware that there are specific requirements for your arrival in Kwajalein for Bikini trips. For full details, please read the following documentation: Procedure for guests arrival in Kwajalein for Bikini.
The Marshall Islands official languages are English and Marshallese, and Christianity is the predominant religion.
The local currency for the Marshall Islands (Bikini Atoll) is the US Dollar (USD). Some of the hotels, resorts, shops and restaurants may accept credit and debit cards, however the great majority may only deal in cash.The Marshall Islands have limited ATMs. Only the ATM at the Bank of Guam accepts international cards and it sometimes does not work. It is recommended to bring sufficient USD in cash, preferably in smaller denominations for convenience.
There is no ATM in Ebeye, but there are three in Majuro.
Cellular cover and internet are available around Majuro and Kwajelein Atolls. Once you leave these islands, the cover will be non-existent and communciations are covered mostly by shortwave radio.
The climate of the Marshall Islands is a tropical climate, with temperatures averaging between 27 and 29C (80-84F) all year round, with some trade winds and a light cooling down in the evening. Generally, the northern islands tend not to receive as much rainfall as the southern islands.
In the Marshall Islands, medical care is very basic with the ‘best’ medical facility in Majuro. Any form of treatment other than basic requires evacuation. Normal precautions should be taken with food and it is advisable to drink bottled water only.
There is no recompression chamber available to civilians anywhere in the Marshall Islands. In the event of a diving emergency while in Bikini Atoll, the vessel will immediately return to Kwajalein to facilitate transfer by emergency air evacuation for treatment (either to Hawaii or Australia) or, if circumstances allow, standby for an emergency evacuation from the airfield at Bikini.
PLEASE NOTE: We do not support 'in-water' recompression.

- 2 Reels or spools – One with a minimum 15m of line and one with a minimum of 60m of line.
- Dive Slate or Wet Notes – Additional to the one used with the emergency SMB or a set of wet notes.
- Minimum of two dive torches (primary and back-up).
- Backplate, harness and wing – capable of carrying manifolded twin 11.1L (80cuft) aluminium cylinders AND one or two 40/80cuft aluminium stage cylinders. The wing should have a minimum of 20kg/45lb of positive lift.
- Two DIN regulator sets one with long hose configured for twin cylinder operation.

- Spare mask – to be carried on all dives.
Divers are advised to bring appropriate exposure protection for extended bottom times and prolonged deco-stops.
Generally, either 3mm or 5mm full-length exposure suits are suitable. A 3mm suit may be appropriate for those who do not feel the cold, although a 5mm suit may help wreck divers reduce the risk of injury from sharp objects and provide additional thermal insulation for extended dive times.
Our vessels operating in Bikini Atoll are equipped with booster pumps for supporting the rebreather diver and have additional stage / bail-out cylinders available on board to rent. We can also supply Oxygen and CO2 absorbent (Molecular Products 797 Sofnolime); The scrubber is charged per kilo and O2 is charged per fill.
Pre-booking of any rebreather supplies is essential to guarantee availability for you. Please complete the Technical Equipment & Gases Request form, and return it as early as possible to contact our reservations team to place your order.
- We DO NOT have M26 valves or adapters on board. Guests are advised to bring their own if they need them.
- We cannot supply pre-packed sofnolime cartridges for rebreather units such as Poseidon.
- Spare oxygen cells and specialist rebreather tools are not available so divers should bring their own.
Pacific Master is fitted with 220V-50 Hz, Australian style sockets. Although there are some universal adapters on board, we strongly advise bringing your own to ensure you have the type and quantity you need for all of your personal equipment.
Solomons Master (previously Truk Master) runs on 110V/220V-60Hz and is fitted with universal power outlets that can fit most European and US plugs.
However, as European, and the majority of other non-US electrical equipment generally requires 220V at 50 Hz we advise bringing power converters and plug adapters with you to avoid potential damage to your equipment and ensure it charges correctly.
Most of the areas visited are out of range from normal mobile phone cover, specifically once the vessel is outside of Kwajalein or Ebeye. There is no Wi-Fi or satellite internet access onboard although there is a satellite phone available to use in case of an emergency.
