Fakarava doesn’t mean a whole lot to the average traveler. However, to a scuba diver, Fakarava is overwhelmingly noteworthy for one thing: the Wall of Sharks. This tiny atoll has the world’s largest population of gray reef sharks, numbering around 700 individuals. The reason they congregate here? Their strict, long-term protection; the high-volume, year-round availability of prey; and strong tidal currents that allow them to rest and breathe efficiently.
Here is an interesting adventure story about these islands. In 1947 the Kon-Tiki, Thor Heyerdahl’s homemade balsa wood raft, sailed for 101 days and 4,300 miles from Peru. It braved rogue waves, severe storms, and dangerous sea life until it was caught in a rushing current near Fakarava, at Raroai Atoll. Unable to exercise enough control over its path, the craft was unable either to steer through one of the atoll’s passes or to miss the atoll altogether. As it approached the coral reef making up the atoll, it was hit with a series of massive breakers, some over 15 feet high. The Kon-Tiki finally crashed into the atoll, which is part of the Tuamotu Archipelago. The six-man crew saved themselves from drowning by lashing themselves onto the balsa logs making up the raft. They were able to avoid being sliced to pieces on the sharp, jagged coral reef, making it to a motu (small island) where they were rescued several days later by local villagers who noticed the floating debris of the smashed Kon-Tiki.
In and around the atolls of the South Pacific, life is controlled by the twice-per-day inflowing and outflowing tides. This was true of our 10 days on the Aqua Tiki II. Each phase of the tide lasts about six hours. The tides are also complicated by swells breaking over the reef rims, adding more water to the circular atolls, which then must flow out of the pass back into the open ocean. The Aqua Tiki II is a 59-foot catamaran specializing in scuba diving, and sails out of Fakarava. Our expedition was crewed by Captain Greg, formerly of France, now living in Papeete; our dive guide, Victor, from the island of Tahiti; and our cook/hostess Poe, who lives in Fakarava.
The boat accommodates up to eight passengers. On our trip there was a small and comfortable group of five: Louis from Quebec, Vanessa from Mexico City, Chris from Germany, Stephanie from various locations in the European Union (EU), and Mike, from the United States.
Fakarava is a little over an hour’s flight from Tahiti. The normal itinerary of the boat is to load up passengers in Fakarava and then spend eight days sailing around the Tuamotu Archipelago, with two days in each of four locations. The Tuamotu Archipelago is historically named The Dangerous Archipelago — not because of the many hundreds of sharks you will encounter there, but because most of the islands sit just a few feet above sea level, unlike the “High Islands” such as Tahiti and Moorea, which have volcanic peaks.
This is the rainy season in this part of the world and there was plenty of rain, along with the accompanying high swells, large waves, and strong currents. Pass entries through the atolls can be treacherous under normal circumstances, with currents reaching in excess of 10 knots, creating standing waves known as “mascarets.” The entries can be much harder under heavy weather.
The Aqua Tiki II is equipped with advanced navigation, safety, and communication equipment, which is especially important because assistance, if needed, would be a very long distance away. Captain Greg was always on alert so that there was no danger of being “Kon-Tiki’ed.”
Because of the heavy weather, the boat had to change its itinerary slightly, and we didn’t make all of the anchorages, but we still had eight great days of diving with two dives/day.
Mike went diving in Fakarava about three years ago, and considered it the best dive he had ever had. On this trip it was magical to be there for a full 10 days of diving and gawking at sharks, manta rays, octopus, dolphins, and many schools of thousands of colorful tropical fish.
Having dived there before, Mike knew it would be a relatively intense experience, with strong currents and fairly deep dives. Due to the topography of the seabed, the current flow was sometimes pretty complicated. If a diver got into the wrong depth or position, he or she could be swept away from the group. Fortunately, that never happened.
Unlike most dives Mike had done in the past, every diver had to have a dive computer. Decompression stops were a possibility on many of the dives, and several times people had to do short ones. Victor, our dive guide, was always on top of the plan, keeping everyone safe, but never being intrusive. We were lucky that all of the passengers had the experience and skills to keep themselves out of trouble and not hold up the group.
Some of the photos and videos below were kindly provided by the crew and passengers.
