Poindimié is the largest town on Grande Terre's east coast, roughly halfway between Nouméa and Hienghène on the long, slow RT3 coastal road. It is essentially a one-street settlement strung along the lagoon, with the central marché communal doubling as the social heart of the surrounding tribal communities.
This is not a destination in its own right so much as a base. The reason to stop is the lagoon — protected by an outer reef, the water here is clear and full of fish, and the Plage de Tiéti just north of town is the most accessible beach on the whole east coast. The reef pass off Tiéti is one of New Caledonia's better-known dive sites, with regular sightings of reef sharks and turtles. Behind the coast, the Tchamba and Amoa valleys run inland into Kanak tribal land and rainforest.
Poindimié has the only proper hotel between Bourail and Hienghène, a modest petrol station strip, and a small airport with sporadic Air Calédonie flights from Magenta. Most travellers arrive by car, having driven up over the central range from the west coast. Allow a night here if you are doing the east coast loop properly — it breaks up the long drive, and the snorkelling makes it worthwhile.
