Caroline atoll was the absolute highlight and the main destination of my 2019 catamaran expedition in the Pacific Ocean.


This atoll lies around 837 km to the North of Tahiti, but it's 24 hours ahead in time. So if it is Monday on Tahiti, it is already Tuesday on Caroline - and technically, those who are on this atoll are in front of everyone else on Earth in time. This cruise had only two participants: my talented Polynesian captain, Teahui, and myself, the crazy man who in 2018 came up with the idea of contacting a Tahitian catamaran charter company, Poe Charters, to go to this remote atoll. Among the captains of this company nobody has ever been to Caroline atoll, so when this project emerged, all the captains were competing to get the job. No wonder the job was given to the best, the craziest, most daring captain. Teahui said this was a once in a lifetime opportunity for him!


Our trip started in Tahiti. We haven't even justify the outer limit of Papeete's harbour - and we already got visit from playful dolphins at the bow of the catamaran (the boat's name was Poe Reva). After a few hours of sailing in good wind we reached Tetiaroa, Marlon Brando's private island. You might have already seen my tour about this beautiful royal island here on Airpano. I spent a few hours flying over the lagoon of Tetiaroa, then we headed directly in the direction of Caroline atoll. As we passed in front of the Brando resort, to the West of the island, the horizon was ablaze with orange colours of the setting sun, and the ocean was relatively calm. Night came abruptly as it always does in the tropics, within minutes you are in pitch dark if there is no moon. During the night we quickly realised that the wind will not be sufficient for us to give enough force to reach Caroline atoll solely by sailing. Our speed dropped drastically. So we decided the next morning to modify the route, and we headed for Rangiroa atoll's Avatoru pass. Teahui navigated the catamaran skilfully in the crazy waters of the pass (which is subject to tremendous waves, vortexes and turbulences of water during high and low tides). In Avatoru we parked the catamaran and I went by taxi to buy up all the canisters available on the island. It was nice to see this island again, since two years before I stayed here a week. I spent more than 600 euros just on the plastic canisters for the extra fuel we needed. We replenished the tanks and the "bidons" too (as they are called in French). I made a few panoramas of Avatoru Pass, and then we continued forward to Caroline atoll.


During the long crossing of the open ocean, we had to stay on guard duty during night-time - each of us did 3 hours, and then we switched. Imagine to be woken up at one o'clock in the morning, go to the decks, and check the horizon every 20 minutes for possible presence of other boats or for upcoming weather events. I also had to check the navigational parameters of the autopilot, to make sure our heading is still correct. We never encountered any other ship. Not a single one in our 18-day, 2400 km long expedition. A ghost part of the Pacific Ocean! During night, you had to be extremely vigilant on the deck: if you fall into the sea, your life is over. Teahui would never hear my screams because of the noise of the engine, and in the dark, it would be very hard to locate me among the waves. It would be game over! Therefore we had a strict rule of not drinking alcohol at all. We also had to check for weather. Rain clouds usually mean two things: either the total stopping of wind, or extreme harsh wind suddenly, so in such a case we had to lower the sails to avoid the possibility of damage.


One evening, at around 10, we were sitting on the top of catamaran talking, when almost in the same moment we both realised that something is fooling our senses: I have been looking at the horizon, to the East. It was a clean night, a few clouds only, the moon already well above the horizon, hovering between clouds as if framed like an old painting. Then it seemed to me that the moon - as if being a solid piece of ball - was jumping up and down, and also jittering sideways. This could not have been atmospheric shimmer, since the image of the moon was crisp, clear, its perimeter neat, razor-sharp. It moved as a whole, as one single block. Then I tried to fix with my eyes one of the close lying clouds as a reference: it was obvious to me that the moon's apparent distance to the cloud is frenetically changing. While I was thinking about this, we both asked the same question at almost the same time, after a long silence of observing the scene: What the heck is wrong with the moon??? My assumption is that this is a new type of optic illusion, generated by our brains. Since we were sitting on the top of a shaking vessel, our brain tried to stabilise the image in our heads, and this might have caused this strange phenomenon (I have only found one mention of this in the internet).


At a cruising speed of around 6 knots (roughly 12 km/h), it took us around 50 hours to arrive at Caroline atoll. How excited we were among the rolling waves when we first caught glimpse of the slim slice of land of South island! The presence of an island was already announced by the numerous seabirds who were out on their daily food hunting mission. They were very curious and already in a distance of 40 km from the atoll they approached us very closely. They were especially mesmerised by our fishing bait which was trailing 30 meters behind us in the water (we never caught any fish during our trip!).


The timing of our arrival was really great: it was still before noon, so we had the sun behind our back. This is crucial if you want to attempt entering the Blind Channel of Caroline atoll. It is called "blind" for a reason. It actually does not lead into the lagoon, but to a sand-shoal of South island. As no-one ever from Poe Charter came here, I did some research myself prior to the trip. I have read the book of Ron Falconer: Together alone, describing the years he spent here together with his wife and two kids. He also gave hints as to how to enter the Blind channel. I also managed to find him on facebook, so we had lots of conversation prior to the trip. When we arrived at the Blind channel, our GPS showed that it lies right in front of us, yet it was very difficult to see it with waves rolling and breaking everywhere. We were really surprised to see how narrow it is. Is this really the Blind channel? That's all?! The usable part was maybe 16 meters wide! The first thing you see is some shipwreck at the entrance - this is the welcome sign of Caroline! :) We also knew that this channel had some rusting iron bars protruding from under the water. These are remains from some leftover fishing cages from around 20 years ago. I only dared to show the report about this to Teahui two days before our arrival. I told him: "I think you should read this." I was nervous to see him read it, for I knew it made him uneasy. The plan was that I stay standby with the catamaran out in the ocean while Teahui goes with the dingy (we also called it zodiac) to check the passage and see the iron bars. However, the pressure and the stress on us was such that upon arrival he just immediately went for the entry. I prepared all my essential stuff ready for evacuation in case something hits the hull and we start to sink. Teahui made a fantastic entry manoeuvre. He called it a kind of suicide: no seasoned captain would ever risk getting inside with a catamaran this size. It is just too much risk! Right after reaching the gorge of the channel the catamaran had to be turned to stay clear of the coral walls of this passage. When we stopped and dropped three (!) anchors, the welcome committee has arrived. Loads of sharks! Not the very kind natured ones, since this place is so remote that even the black-tips are very aggressive, they are simply not used to see humans. When checking one of the anchors, Teahui had to kick away one grey shark with his fins. He is a native Polynesian from Tahiti, grew up with sharks and riding up to 5-meter high waves, and yet these sharks here were unsettling for him too. Better not to risk injuries so far from civilisation! Being this remote gives one a special feeling: it is amazing to see a place of great beauty largely untouched, but the further away you are from mankind, the more nervous you get. You realise even more how small we are, especially right in the middle of the vastest ocean on Earth, the Pacific! Actually, our planet should be called Water and not Earth, since more than two thirds of it are covered with water.


Once safely anchored (at least this was what we assumed), we had lunch, and then immediately started the aerial photography work. If you look at these panoramas you will see that the lagoon looks like a labyrinth. At some points the water is so shallow that even with our rubber dingy (which has close to zero draft in the water) it was not possible to pass. At some place we had to get out and push the boat and walk - watching out for sharks, for when you are wading in shallow water they think the splashes of your feet are made by fish in trouble, and that means lunchtime for them. Sometimes we had to jump on the boat if they came too close. Normally we are not afraid of these types of sharks, I regularly swim and dive with them elsewhere in Polynesia or in West-Papua's Raja Ampat archipelago: with black-tip sharks, lemon sharks (which are quite huge), reef sharks, white tips (but of course not with the oceanic whitetip, which is one of the most aggressive shark breeds). But Caroline is a crazy, wild place regarding sharks. Your only chance of snorkelling here is by being immersed in water with full body, so the sharks can see you actually and measure your size. And then you just kick them if they get too close. In the media sharks are still demonized and people are very scared of them. For me, sharks are like dogs: most of the shark breeds pose no danger to humans, but there are a few breeds which have a natural tendency to be overly aggressive, and with those you have to be careful.


In the evening we went to Motu Ana-Ana (motu means small islet in Polynesian), I wanted to see the remnants of the small settlement that the Falconers built. I could still see the oven with the built in bottles. I wanted to make a land-based panorama there, but then I was attacked by an army of ants. So I gave up on that plan!


Back on the catamaran, I gave a call to my parents in Hungary with our onboard satellite phone, waking them at 5h30 in the morning. Later in the evening Teahui and me were discussing the next day. We would get up very early. Teahui recommended to go to the very North of the atoll first, and start panoramas there, and then gradually descend back to the South. I had a very detailed flight plan for my two drones for the 6 days we planned to stay here on Caroline. I was suggesting instead that we spend the first full day around the middle section of the atoll, since this is the most exquisite, most beautiful part of the island, and I wanted to make sure that I do the most beautiful panoramas as soon as possible. After all, you do not know what will happen, maybe bad weather or other problems. Who knows?


After an early rise, we had our breakfast and already at 6h20 the sun was pounding on us with an extreme force. We clothed in full white, long-sleeves only. We also used colourful sunblock on the cheek and under the eyes, this product is physically covering the skin and thereby shielding it from the burning sunshine. We started our slalom in the lagoon, for Teahui had to learn the twists and turns and discover the secret inner ways of this lagoon. We enjoyed very much the manoeuvres - we burnt also a lot of fuel for it is very difficult to go around. Let us not forget that our dingy is made of rubber, and the atoll is made of razor sharp corals. I leave it up to you to make the connection! :) This is an incredible place: though the vegetation can be rather lush, often times it is composed of shrubs  which provide little shade! So I had to crouch like a rat under some bushes which gave not much relief from the sun and it was very difficult to see what is going on the screen while flying the drone. At least I experienced how life is for birds on these motus. The atoll is home to at least one and a half million birds. Some chicken are just waiting in the blazing sun all day while their parents are out in the ocean fishing. They are also very tame, you can get very close. By the end of the day I made 36 panoramas, including those I shot the day before so I was really satisfied. When we were heading back to the catamaran we really hoped the catamaran would still be there and not washed out into the open ocean. We were relieved to find it there neatly tucked into the Blind channel. A fish caught by Teahui from the lagoon at the Blind channel (sharks were slow and we managed to keep it for us!) was cooking in our onboard oven. We were looking forward to a delicious meal, but then we saw that the fish started to foam. Well, not a really good omen, so we decided we would not eat it. It could have had ciguatera. Ciguatera fish poisoning (CFP) is a food-borne illness caused by eating reef fish whose flesh is contaminated with certain toxins. So after all the sharks still ended up with our fish.


We were having a relaxed evening talk and each of us went to do some reading, before sleeping. It was pleasant to be able sleep in a more or less steady boat, since now we were quite well protected, not out in the open ocean. Well, our peace was not long lasting.


Around 2 in the night I was woken up by some terrifying noises: metal scratching on metal, scraping sounds. This sounded really-really menacing. Of course I knew immediately what it means: our anchoring was drifting, our position became unstable. The leftovers from the fishing cages, the iron bars in the water were helpful for us in the beginning, since one of the anchors got stuck in them, but after one and a half days they could not bear our weight, not even together with the other two anchors. I went up, but could not see anything, there was no moon and it was totally dark. I could not see Teahui. Later it turned out that we went up to the deck to check the situation at different times. But since in pitch dark it is impossible to do anything, we just had to wait this out. At one point I could also hear a frightening sound consistent with plastic scratching on rock - which means that our catamaran was also touching the sides of the channel, where the water is barely half a meter deep at low tide. At first light we evaluated the situation and Teahui tried to stabilise the boats anchorage. Unfortunately the currents did not allow this, and while trying, we also lost one of the anchors along with the rope. So finally we decided that instead of sinking our catamaran we would now decamp. After just 2 nights! But I was not too frustrated - I already had the most beautiful set of panoramas I ever did, and I covered the key locations of the atoll. And safety lies above all! But I am not someone who easily gives up: we immediately decided that we shall return to Caroline (or Carolina as Teahui cheerfully called the island). Anyway, we need to recover the lost anchor, we know exactly where it lies, it is just at 4-5 meter depth. But for the next trip we will be three on board: there will be one more crew, so somebody will always stay on the catamaran to keep full control and supervise our floating home. If the swell won't permit an entry to the Blind Channel, the catamaran can still stay out in the ocean at standby, sailing up and down without stopping. You have to understand that it is impossible to anchor the vessel outside the atoll: the reef falls too abruptly to huge depths (during most of our odyssey the ocean's depth was 4.5 km!). If you approach the relatively shallow side of the atoll and drop the anchor, then you will be too close to the shoreline where the waves break. You do not want to lose your anchor and end up rolling and breaking on the coral reef – just as Marlon Brando did with his fisherman when he first crash-landed on his beloved Tetiaroa atoll. Our next trip will take place in April/May 2021, dates are already set, we shall visit of course Caroline, but also many other atolls in the Tuamotu archipelago!


Leaving the Blind channel was just as challenging as entering it. It was heavily turbulent, the amplitude of the waves was very high, and at the trough of one of them we almost hit one of the coral heads at the side of the channel, we were roughly 40 cm short of it. Good that we wore our brown trousers (just kidding)!


After Caroline we suddenly found ourselves with loads of extra time, so this permitted some spontaneous island visits. I decided that we first head to Tikehau. One of the funniest moments out on the motues was when our Zodiac was washed away by the waves and we only noticed it late, and we were justify stranded on a little islet with no boat and the catamaran anchoring quite far from us inside the lagoon. That is when I saw Teahui run and swim the fastest, at olympic speeds. But we got back our boat, otherwise we would have asked a fisherman to help. After Tikehau we cruised back to Rangiroa, and we went to the Blue Lagoon where I made a quite extensive aerial and land based panorama survey of this magnificent garden of Eden. I, Adam, first of his name, absolutely approve this paradise. Inside the giant lagoon of Rangiroa (74kms long!!!) we had some massive swell (rhythmic waves), so leaving the catamaran with the Zodiac, boarding and disembarking was an extra challenge, but Teahui at least could enjoy wave surfing with our rubber Zodiac boat. So much fun it was! After Rangiora we went to Mataiva atoll. We set the engine speed such that it matched the rhythm of the swell coming from the East, so this was the best cradle-like experience we had on the catamaran. One of the best nights! Next day I had a visit of Mataviva atoll where the locals treated me with outstanding hospitality and I received a sumptuous set of necklaces made of seashells. (Mataiva impressed me so much that it will be the first stop of my expedition in 2021.) By the afternoon trouble was already looming on the horizon, massive black clouds were emerging from the East. When I went back to the catamaran the swell was already 2-3 meter high. Putting the drone (and myself) back to the catamaran among the waves and in the rain was already a nice challenge. At this point we were still on the Western side of Mataiva, so relatively shielded from the Armageddon that was lurking around the corner. The swell soon became enormous, 4-5 meter waves, but with a nice wavelength, the period of the waves was quite long.  We were heading to Makatea now, but the moment we justify Mataiva's protecting landmass and darkness came down on us, all hell broke lose. Extremely short wave periods, 4-5 meter waves coming right from South-East, head on, 70 km/h winds, rain and darkness. It took us 9 hours to reach Makatea, but the forces to which we were exposed were astounding. According to Teahui grown-up man cry in such situations. Well at least I found out about myself that I do not, and under this stress I remained stoic and calm (I was already on land in Tahiti when the stress came out of me and I realised what we went through). We were of course afraid, one has to be really stupid not to be afraid. The period of the 5 meter waves was just a few seconds. Since the catamaran was only around 12 meter long, when we reached the top of the 5 meter waves, the hull of the boat turned over the peak like a seesaw, the propellers, normally submerged in water, were out of the water and you could hear them choking. And then you sharply turn downwards and fall in a free fall and you hit with full force the trough of the waves, only to be lifted up again to the crest, and then restart the cycle. For 9 hours non-stop! We found out later that in French Polynesia all boats stayed safely sheltered in protected lagoons and basically few were out in the open ocean. Only the crazy ones. Like us. These were the very same weather conditions that on Tahiti's Teahupo generated one of the greatest swells of the last decade. But let's stop my tale of the journey right here and turn our attention back to Caroline.


After my own words I would like to introduce you Caroline atoll in a more formal manner. For this, I will cite passages from a study of Caroline atoll prepared by Angela K. Kepler and Cameron B. Kepler. It was published in the Atoll Research Bulletin No. 397 under the title "The natural history of the Caroline Atoll, Southern Line Islands". I am grateful for this study as it provided me lots of valuable information for preparing my trip.


Caroline atoll, also known as Millennium Island and Beccisa Island is the south-easternmost of the Southern Line Islands, a group of 3 islands which also includes Vostok and Flint. Although archaeologically and geographically within Polynesia, Caroline is owned by the Republic of Kiribati (correct pronunciation: kɪrɪˈbæs) formerly Gilbert islands. Caroline atoll is neither physically, geographically, nor politically associated with the Caroline islands, now part of the Federated States of Micronesia, more than 6000 km to the northwest. According to the path of the International Date Line, Caroline Island is the easternmost point of land on Earth.


Caroline Island is believed to have originated from a volcanic hotspot which eroded and then became home to a coral reef which grew above the ocean surface. Although these geological processes are poorly understood, the orientation of the Line Islands (roughly north–south) suggests that they were formed more than 40 million years ago, before the Pacific Plate changed its direction of travel. The same hotspot more recently gave rise to the Tuamotu Archipelago. Caroline's islets are particularly ephemeral— over the course of a century of observation, several of the smallest islets have been documented to appear or disappear entirely following major storms, while the shapes of larger ones have significantly changed.


Caroline, 9.7 km long, 2.3 km wide at its widest point, and 26.9 km in circumference, is a crescentic coral ring with 39 islets (motus) centred on a continuous reef enclosing a relatively shallow lagoon. The closed lagoon, rich in marine life, contains a maze of patch reefs and impeccably clear water. The atoll, uninhabited, was "discovered" by de Quiros in 1606. Although traces of an ancient Tuamotuan culture still exist, the atoll apparently never supported  a long-term population and has been less affected by man than most Pacific islands. Its European history includes guano export, a multinational expedition to observe a solar eclipse, and copra production. It has been uninhabited since the early 1930s (a factor contributing to its relatively undisturbed ecology), except for the presence of Ron Falconer's family from 1987 to 1991. In the past decade, a lone French sailor called Lyderic set up camp on the shores of Motu Ana-Ana, but he was expelled and imprisoned by the government of Kiribati for staying there several years illegally. The primary factors responsible for the atoll's lack of permanent settlement are remoteness, apparent absence of usable ground water, repeated failure of its coconut plantations (diseases, destruction by coconut crabs, rats and seabirds, smothering by vines), absence of a passage into the lagoon, and a paucity of safe boat anchorages.


Most of the islets of Millennium Atoll are flat and densely vegetated with forests of Pisonia grandisCordia subcordata and Heliotrope (Tournefortia argentea)— representing some of the most intact and largest forests of these species remaining in the Pacific. Other areas of the atoll have scrub-type vegetation. The islets are internationally important as major seabird breeding sites, and Millennium, together with Flint, have some of the world's largest populations of the terrestrial Coconut Crab (Birgus latro).


Centuries before Europeans encountered Caroline, the atoll was inhabited by Polynesians. No oral traditions of this occupation are known, but evidence of former habitation was evident when the Portuguese explorer Pedro Fernandez de Quiros found the atoll in 1606, naming it San Bernardo. He noted "an old canoe, lying on her side". In the 1870s 50 ancient Polynesian sites were unearthed which were later identified as Tuamotuan marae. Marae, according to ancient belief, "bound the ancestral spirits and gods of the kindred to the land, putting it under their eternal guardianship". Despite its remoteness, Caroline was encountered early in Pacific history, long before Tahiti, Rarotonga and Hawaii.


As Caroline Island only extends six meters above sea level, it would be in danger if sea levels rise. The Kiribati government estimates that the island may be reclaimed by the sea as soon as 2025, and the United Nations has rated Caroline Island as among those most in danger from sea level rise.


Caroline Island is among the most remote islands on earth – 230 km from the closest land at Flint Island, 1,500 km (930 mi) from Kiritimati, 4,200 km from the Kiribati capital of Tarawa, and 5,100 km from the nearest continental land in North America.


Caroline Island is heavily vegetated, and most islets possess three ringed zones of vegetation: an outermost herb mat; an inward zone of shrub; and a central forested region, typically dominated by groves of Pisonia grandis trees. Coconut palms have also been introduced and exist in substantial quantities on the larger islets. Caroline Island is an important breeding site for a number of species of seabirds, most notably the sooty tern, numbering around 500,000 – a colony of sooty terns dominates the eastern islets – and the great frigatebird, numbering over 10,000. Caroline Island and its neighbour, Flint Island, also host some of the world's largest populations of the coconut crab. Other native animals include the Tridacna clam, which is abundant in the central lagoon, hermit crabs, and multiple species of lizards.
