The Diahot

The Diahot is one of the emblematic natural sites of northern Grande Terre. Located in Ouégoa, this river is often described as New Caledonia’s only river. It flows through preserved landscapes before reaching the sea via a vast estuary, making it a striking landmark of the region and a memorable discovery for visitors drawn to nature. Its estuary is especially remarkable for its extensive mangroves, considered among the most beautiful and expansive in the country. This natural setting adds to the site’s scenic appeal and ecological richness, where freshwater, marine environments and coastal vegetation meet. The area is also part of the lagoon zones recognised by UNESCO, further highlighting the Diahot’s environmental and heritage value. The Diahot is also an important local resource and closely tied to everyday life in the area. Lined with mangroves, it is valued for fishing crabs, prawns and fish. For visitors, it is best discovered from the water, offering a deeper appreciation of its landscapes, the peaceful atmosphere of its estuary, and the diversity of its fauna and flora.
