The Most Remote Diving Expedition in Indonesia | The Banda Sea

A vast, deep blue, almost infinite, its horizon broken only by a few silhouettes. Volcanic islands, their cones ethereal in the distance. This forgotten sea, shadowed by two giants, Komodo and Rajampat, remind me that Indonesia still holds countless places yet to be discovered. Accessible only for a short window each year, it was long overlooked by Indonesian cruise vessels. To reach its islands and reefs, one must sail hundreds of nautical miles and accept the unpredictability of its wild nature. The Banda Sea. Tamed. What secrets does its islands and reefs hold? What does it offer beyond its neighbouring archipelagos? As if Banda itself was calling me. Every year, I return to its most remote reaches in search of a new discovery, keep their secrets. I always find the same feeling, the silence, the open water, the unknown. People often ask me, Alex, do you prefer diving in Komodo or Raja Ampat? I can't help but smile, amused, before drifting back into my own thoughts. I've always sought out wild, untouched spaces. It was while pursuing my master's in anthropology that I discovered La Réunion and Madagascar. But the call of uncharted adventure was stronger. For nearly 10 years, odd jobs funded my journey through South America and then Southeast Asia. Eventually, my wanderings led me to Northern Australia, where I worked as a bricklayer for nine months. By March 2012, the decision was made. Tired of that life, I left Australia and set out to become a dive guide in Indonesia. A diver since I was 15, I became an instructor in Bali and was soon hired as manager aboard a boat operating exclusively in Komodo. I learned the ropes and picked up Indonesian language while living alongside the crew. Fresh from the Eastern Indies, Captains and crew of the great pinnace ships would share story of their adventures of the edge of Indonesia over Ubin town. I knew only Komodo and yet I listened. Captivated blue whales, colony of sea snakes, school of hammerhead sharks and the unpredictable mysterious waters they called the Banda Sea. At that time most ships merely passed through. A simple repositioning journey between Komodo and Raja Ampat. In 2014, I bought a small daring 25 meter cruise boat, my loyal companion Lambo, which would become my home for the next five years. Aboard her, surrounded by an experienced crew, I first explored Raja Ampat, then the northern Moluccas. Yet the boat continued to travel empty between Komodo and Raja Ampat. I had to convince the owner. He considered the long crossing too risky and exhausting for the crew. But after persistent arguments, I finally won his blessing. I'll never forget his words. Okay, go ahead, do it right and figure out how to find the clients. That was all I needed. With a few GPS points gathered from other cruise directors, I chartered my own route. A handful of intrepid travelers trusted me, hoping to find exceptional dives. All that remained was to mobilize the boat for its very first crossing from Alor to Ambon. Without knowing it, this marked the birth of the first Kanjo expedition. What if I told you that Indonesia, a country more than 70% covered by water, was shaped by fire? It rests on one of the planet's scars. The Pacific Ring of Fire. At the crossroads of four tectonic plates, it's the most active volcanic arc in the world. Within the archipelago, over a hundred volcanoes are still alive today. Over millennia, this power has carved mountains and fertile islands. It is also the source of some of the most spectacular marine environment on the planet. A major oceanic current flows here from It steers cold, nutrient-rich waters, fertilizing the reefs in its path. It finally reaches the Sunda Strait before being pulled toward the Indian Ocean. In the Alor Strait, the beauty of the reefs is exceptional and marine life thrives. The hypnotic dance of damselfish and blue triggerfish turns every dive into wonder. Traditional bamboo fish traps Stand like silent sculptures, while the reefs come alive to the rhythm of encounters with the most unexpected inhabitants. But beyond Alor, everything changed. Suddenly, the archipelago fades. The horizon clears of land, plunging into the abyss of the Banda Sea. Islands become rare, scattered, like shards of rock set in emptiness. Only submerged reefs and isolated volcanic islets testify to its power. Around them, the ocean plunges over 5,000 meters deep. The deepest point of the Banda Sea dropped to 7,531 meters, the mysterious Weber's Trench. An almost unfathomable abyss, its vastness, shoals rise out of nowhere, becoming magnets for marine life. Their sheer walls are colonized by massive barrel sponges and centuries-old hard corals. In this suspended space, big-eyed trevally move in tight schools. Red and black snappers and surgeonfish swire endlessly. Bumphead parrotfish bite the reef with relentless determination. Napoleon wrasse glide along the drop-offs, accompanied by elegant stingrays drifting into the depths. Another emblem of the Bandasie. The Leopard Moray Eel, and in the shadow of the reef, the spotted soapfish. Today many of these reefs are known to cruise captains. Yet venture just off the main route and you descend once more into the unknown. Because there are others, still nameless, waiting to be revealed to the most curious divers. During my recent explorations of the Key Islands, a fisherman named Gino told me about a ghost reef, Karong Mas. the Golden Reef, invisible on nautical charts. Gino promised to take me there on my next visit. It is these conversations, on the edge of a canoe, on a forgotten beach, that give exploration its true meaning. But trust cannot be invented, it is built patiently. It is through this mutual trust that locals eventually share their secrets, their hidden reefs, their stories. Their knowledge, beside these underwater reefs bordered by the abyss, isolated and uninhabited volcanoes fracture the earth's crust. Blue-footed boobies and frigate birds have made them their home. Beneath the surface you can even see the volcano breathe. Every year National Geographic teams come to document this unusually high concentration of sea snakes here. These unique conditions stimulate the metabolism of our cold-blooded marine reptiles. These aren't the classic banded sea snakes, they belong to the genus Hydrophis. They are true ocean predators, born, hunting and mating entirely at sea, where their relatives must return to land to digest or reproduce. Graceful, unnerving, venomous yet harmless, It's mesmerizing to watch them hunt, followed by trevally who have developed an opportunistic hunting strategy. Lost in the middle of the ocean, reefs are never truly alone. Around them live some of Indonesia's most isolated island communities. They read their sea like an open book. They know every current, every shoal, every hidden contour. They are the silent guardians of these worlds outside of time. People of the Banda Sea live by two things, spices and the sea. Everything here depends on nature and what it is willing to offer. Fresh water is always a challenge for these communities living in near self-sufficiency. There are springs but many villages rely entirely on rain. This karst city grows toward the end of the dry season when the nutmeg harvest draws seasonal workers. Often they are descendants of exiles telling a forgotten chapter of this island's recent history. Under Suharto rule the government tried to relocate residents to the larger surrounding islands to make administration easier. Only a few families remain year-round. Children over five attend schools more than 150 nautical miles away. But some refuse to leave faithful to their land. To their ancestor, silent guardians of a forgotten island. And then there's me and us, the fleeting visitors. Some westerners see me as an intruder, a voyeur, here to disturb or corrupt the autonomy of these islands. Everyone has their own perspective. I'm here simply to listen, to share a kind, brief moment of exchange. But for me, these encounters, even fleeting, are worth more than any judgment from a western world still carrying the weight of its history. Seasonal thermoclines sparks an explosion of life. When the east winds push surface waters aside, cold nutrient-rich currents rise from the depths. The opportunity is so intense that dive operators arrive earlier each year, braving the winds as early as late August. It's the perfect moment to witness pelagics and the great marine mammals. Guided by these currents, creatures leave the darkness to reach the sparkling reefs, completing the final link in the food chain. Our species reveal themselves. The silver-tip shark is a curious visitor approaching divers without hesitation. Far more discreet, the majestic thresher shark can sometimes emerge from the depth. Of course, the schools of scalloped hammerhead sharks. Another great traveler seems to always follow our cruises, the awe-inspiring pygmy blue whale. On my last journey, Wendy Mitchell, an Australian conservationist, managed to film several with the help of her drone. She explained how essential Banda is for their migration. They come here to feed and perhaps to give birth. They travel from the coast of Australia to Timor and then here before returning to the southern seas. Large groups of dolphins regularly follow the boats, playing in the bow, as if to remind us that this ocean is alive. still and always Swan Gir Rock is only a night sail from Ambon, pristine reefs and the near daily appearance of hammerhead sharks still endure. With increasing visitor numbers, local authorities have acted. Coring is now prohibited and only three boats are allowed by day. This is a deliberate effort to manage tourism, giving these majestic predators a sustainable refuge away from the most vulnerable zones of the Banda Sea. Once, this archipelago around Neira was the center of the world. Nutmeg was more valuable than gold. Portuguese, Spanish, Dutch and English fought mercilessly to control the spice trade. Today, tourism is becoming an economic driver, visiting plantations, tasting nutmeg-based products, exploring Fort Belgica and small-scale accommodations. In 2016, joint initiatives by villagers and local and international NGOs led to the creation of a marine protected area. A fragile balance between essential fishing and preserving exceptional reefs. After the last eruption of Gunung Api in 1988, one of the Indonesian most beautiful hard coral gardens emerged along the lava flow. A spectacle of raw, unfiltered beauty. Like many regions of the world, the Banda Sea faces growing challenges. Climate change, Demographic pressure pushing fishing vessels even farther offshore. And shark finning threaten the sharks and marine mammals that still inhabit these waters. Species now at risk. Tourism can become a powerful tool for protecting endangered life. Only if local communities lead the way, supported by strong responsible international logistics. The most isolated reefs are often the most vulnerable. Because the immensity of the ocean, the last true frontier of freedom on our blue planet, will remain always, by nature, uncontrollable. But why take the risk of sailing hundreds of nautical miles, when we could settle for five-star dive sites and sheltered anchorages in Rajang Path? Like I do, venturing to the most remote corners of the Banda Sea, are looking for something else, beyond the chance of seeing a particular species. It's about diving into the unknown. Going where few are willing to go. Of surprising fish unaccustomed to human presence. It offers the chance to meet communities whose way of life stands at the far edge of our world offer the possibility of discovering new islands and reefs, creating dive expeditions that carry meaning. That was what led me to create Kanjo. With a single mission, a person may step through it, absorb it, be inspired by it,
