Île des Pins spent eight years as a prison for the losers of a revolution. From 1872 France shipped roughly 3,000 deportees from the crushed Paris Commune to this island of white sand and columnar pine; about 300 never left; their graves still lie in the cemetery at Ouro, beside a water tower the prisoners built in the 1870s, still in use today. The Kunié, the Kanak people who own the island, call it Kunyié. Its European name comes from the tree that fringes every shore and ridge: Araucaria columnaris, endemic to New Caledonia, which grows in a narrow dark column up to 60 metres. James Cook saw them from the Resolution in 1774, named the place the Isle of Pines, and never landed. The limestone underfoot is riddled with caves, and offshore lie the reefs of the Grand Lagon Sud — one of six clusters UNESCO inscribed in 2008, part of one of the three largest reef systems on Earth.
The island's centrepiece is the Piscine Naturelle d'Oro, a shallow basin where the tide pushes lagoon water through a break in the coral; you float there under the pines while reef fish stream past beneath you. At Baie d'Upi, boatmen still sail carved outrigger pirogues between limestone needles rising straight from the water, landing you on a forest path to the pool. Kuto and Kanumera lie back to back — one a broad white strand, the other curled around a coral islet the Kunié hold sacred. From mid-July to mid-September, humpback whales that have crossed from Antarctica to calve in the lagoon pass close enough to be watched from the shore. Today the island is quiet: after the unrest that shook New Caledonia in 2024, flights and cruise calls resumed through 2025, but visitors have been slow to return.
