New Caledonia Turtle Sanctuary

Imagine swimming alongside ancient sea turtles in one of the world’s most pristine marine environments. The New Caledonia Turtle Sanctuary (Sanctuaire des Tortues Marines) is a vast protected area spanning over 1.3 million square kilometres of lagoon and ocean, dedicated to the conservation of five of the world’s seven sea turtle species. Here, the turquoise waters and vibrant coral reefs are a living museum of marine life. Whether you’re a snorkeller, diver, or nature enthusiast, this sanctuary offers an unforgettable encounter with these gentle giants in a setting that feels gloriously untouched.

Highlights & What to See

• Snorkel with turtles at Îlot Maître – This tiny islet in the lagoon is a favourite spot for green and hawksbill turtles, often seen grazing on seagrass just metres from the shore.
• Dive the world-class reefs of the Chesterfield Islands – For experienced divers, these remote coral atolls offer stunning drop-offs and an incredible density of turtles, manta rays, and sharks.
• Visit the Aquarium des Lagons in Nouméa – A great introduction to the sanctuary’s marine life, with touch pools and a turtle rehabilitation centre where you can learn about conservation efforts.
• Take a glass-bottom boat tour from Nouméa – An easy way to spot turtles without getting wet, especially around the nature reserve of Baie des Citrons.
• Explore the UNESCO-listed lagoons by kayak – Paddle through mangroves and seagrass beds in the southern lagoon, where turtles surface for air right beside your kayak.

Suggested Time to Spend

Most visitors base themselves in Nouméa and dedicate at least two to three days to the sanctuary. A full day allows for a morning snorkel trip to Îlot Maître and an afternoon at the aquarium. With two days, add a dive or a longer boat excursion to the outer reefs or the remote Île des Pins, where turtles are abundant year-round. If you’re a serious diver, plan for five to seven days to reach the Chesterfield Islands – a liveaboard trip is essential, and the journey itself is an adventure.
