The Tahiti to Mo‘orea Ultra Marathon Ocean Swim is an unforgettable experience across one of the most beautiful stretches of ocean in the world. This guided 21.2 km (13.17 mile) open-water crossing between Tahiti and Mo‘orea in French Polynesia combines challenge, adventure, and breathtaking tropical scenery in one iconic swim. Imagine gliding through the warm, turquoise waters of the South Pacific, with the lush green peaks of Mo‘orea on the horizon ahead of you. You’ll be swimming in waters known for their clarity, colour, and marine life — including the occasional dolphin or manta ray sighting. It’s not just a test of endurance, but a journey through a living postcard. Tahiti and Mo‘orea are two of the most treasured islands in Moana-nui (Oceania). Tahiti is the cultural and political heart of French Polynesia — a vibrant island with mountains, waterfalls, and black sand beaches. Just 21 kilometres away across the channel, Mo‘orea is Tahiti’s laid-back sister — famous for its jagged mountain peaks, emerald rainforests, and crystal-clear lagoons. We first organised this crossing in 2018 and have since helped guide many successful swims. Each swim is closely monitored and supported by an experienced team, with every attempt officially recorded for official ratification with the international Marathon Swim Federation (MSF) or World Open Water Swimming Association (WOWSA). Whether you're an experienced open-water swimmer chasing your next big goal or simply dreaming of an epic swim in paradise — the Tahiti to Mo‘orea crossing is a rare and unforgettable adventure. We can help you achieve your goal.
