Located in Prony, South Province, New Caledonia, Sources Chaudes de Prony is a unique natural phenomenon in the Pacific.

The site features a lagoon-like setting, adding to its natural beauty and tranquility. Visitors can enjoy a range of spa treatments and activities amidst this breathtaking environment.
Insider tip — The Prony hot springs are accessible only by boat or a long forest hike through New Caledonia's protected southern wilderness, making them one of the most isolated thermal sites in the Pacific. Seawater mixing with hydrothermal fluids creates a warm, mildly salty pool in a sheltered bay fringed with mangroves and towering araucaria pines. The site sits within the Grand Sud UNESCO Natural World Heritage zone, where endemic nickel-rich soils colour the landscape in rust and ochre. Arrive via a sailing day-trip from Port-Oueme for the most memorable approach.
