The Loyalty Island of Maré can be reached by a 40-minute flight from Nouméa-Magenta domestic airport. Once there, it’s a good idea to rent a car (book in advance) to get to the island’s sites of interest. Trou de Bone is located 10 km from La Roche, in the Ghama district on the RM4 road towards Tenane. It’s free to access and there is no need for a guide, so you can get there completely autonomously. From La Roche, take the RP3 first, then the RM4. Around 2,500 metres after the junction, a sign will point you in the right direction to reach the Trou de Bone. Keep your eyes peeled, as it’s quite discreet! The gouffre is on the right-hand side of the track. You’ll leave your vehicle there as it is generally unoccupied and unobstructed by multiple vehicles.
- Wait until the sun is at its zenith to enjoy pristine rays of sunshine bathing the bottom of the cave.
- Take advantage of your excursion to visit the sandalwood factory located on the same road.
- No fee and can be accessed freely (with/without a guide)
