The world‘s finest diving

Truk & Bikini Atoll

The wreck diving in Truk Lagoon & at Bikini Atoll is nothing less than stirring.. It took only 2 days, in 1944, for the U.S. to launch more than 500 strikes against the Japanese fleet harbored in Truk Lagoon and to virtually demolish it. Between 1946 and 1958, 23 nuclear devices were detonated by the United States at Bikini Atoll, sinking a variety of vessels brought there for testing purposes … and today we can safely dive on all of the wrecks which are at recreational depths.

Truk Lagoon has excellent choices in terms of liveaboards and the Truk Master will now be making an annual trek over to the neighboring Marshall Islands during the period of May through August to visit Bikini Atoll, adding new and stirring wreck dives to her repertoire. If you’re a wreck aficionado I can’t recommend this option highly enough! You can read more about them here.

Truk Lagoon: Stirring Experiences, Indelible Memories

The fascinating Truk Lagoon is famous in large part due to its prominent place in WWII history, as the American attacks here on the Japanese forces were a virtual Pearl Harbor in reverse. The wreck diving here is amongst the most stirring experiences a diver can have and the calm, tropical situation of the lagoon offers easy access to the wrecks.

Many of the wrecks are “Maru”, Japanese merchant vessels that were at anchor in the lagoon when the Americans attacked. Some had been fortified with anti-aircraft weapons and many carried important army supplies including Zero Fighter aircraft parts, tanks, torpedo shells, trucks and road supplies. Bottles, cooking utensils, items from everyday life and personal artifacts can be found in several of the wrecks, serving as a reminder to the visiting divers of those who lost their lives during the battle.

For your diving support you have 3 excellent options to choose from: the Truk Odyssey liveaboard is still regarded as one of the best anywhere in the world & has recently undergone some major work; the always popular Thorfinn is a long-popular option in the Lagoon; and the sturdy Pacific Master (which also takes divers to Bikini Atoll mid-year every year) has just moved from the Solomon Islands.

Go For A Combo Trip With Palau Or Yap

You can certainly dive Truk (Chuuk) Lagoon as a single destination but we recommend, if possible, doing it in conjunction with either land-based or liveaboard diving in stunning Palau. Once you’ve travelled all that distance, it’s a shame to miss half the fun ! And …. if you have time, you can add in an unforgettable trip to Yap to dive with the magnificent manta rays who hang out there.

If you choose a combo trip, you may be lucky enough to get from Palau to Truk (Chuuk) to board your 2nd liveaboard on a boat the same day you leave Palau …. for an unforgettable wreck diving experience. Other times, you’ll have a day or two between liveaboard trips … with great places to stay and dive.

Bikini Atoll, Marshall Islands, The History

Bikini Atoll is part of the Republic of the Marshall Islands, which covers nearly 1 million square miles of idyllic emerald-green coral atolls, surrounded by the crystal-blue waters of the Pacific. It lies north of Papua New Guinea and the Solomon Islands … south of Micronesia. It was declared a UNESCO World Heritage site in 2010.

The US conducted nuclear bomb testing here after WWII, destroying an entire “fleet” of “war machines” ready to be retired from active duty. The tests necesssitated that residents to be relocated and very few have been able to return to their home atoll.

Scuba Diving Unlike Anywhere Else

This is a one of a kind diving experience, as it features not only beautiful reefs, corals and wonderful marine life, but above all, it is the final resting place for some of the most significant warships in history. It is often ranked first on a serious wreck diver’s list. You will be able to dive a unique collection of historic battleships, cruisers, as well as the world famous USS Saratoga aircraft carrier with its 270m (888ft.) flight deck. The Saratoga was sunk by an atomic bomb detonation just 400 yards from the ship. She now rests in the sand at 165 feet, along with three airplanes that were blown off the deck.

You can expect to explore up to 10 ships and submarines on your expedition. As mentioned, the huge carrier, USS Saratoga is often the top venue, but you can also dive the USS Lamson and USS Anderson, American destroyers which are largely intact and the USS Apogon, a submarine which hosts corals & sponges, fish & critters … and attracts resident sharks. The Japanese battleship, Nagato, is also very popular. Lying upside down, it’s also still mostly intact, allowing divers to swim through parts of the vessel to explore its inner structure.

Most wrecks in Bikini Atoll are located beyond recreational diving maximum depths; therefore technical diving skills and wreck experience are required. Regular trips on the Truk Master started in May 2018 with a choice of 10 and 11 night trips and a maximum of 11 guests per cruise. Technical diving is, of course, supported.

Due to the success of this program, Master Liveaboards is adding a second vessel to the Bikini itinerary as of 2022.

In fact, they are switching the boats for logistical reasons (the current Solomons boat is larger & can carry more divers to popular Truk & Bikini).

Truk Master is now the Solomons Master … and will do Solomons & Bikini Atoll itineraries
Solomons PNG Master is now the Pacific Master … and will do Truk Lagoon & Bikini Atoll
