The Grottes de Koumac site is public, with free and unrestricted access. Public transport doesn’t go that far, so you’ll have to get there with your own rental car, unless you’ve opted for a personalised guided tour. From the centre of the commune of Koumac in the north-west of Grande Terre, it’s about a 8 kilometre distance. If you’re coming from the south, take the first exit at the church traffic circle, then right again once you’re on Avenue Georges Baudoux. A sign will direct you to the site on your left, 400 metres away. Once over the little bridge, you’ll have to turn right again and walk for another kilometre to reach the caves. The Grottes site is open to the public every day, from 6.30am to 6pm.
- Equipment: bring two lamps (torch or headlamp), pants, closed shoes and drinking water.
- A minimum of 2 people is required to tour the Grande Grotte.
- Don’t forget to write down your names on the register available at the entrance before entering the cave.
- For safety reasons, the site is closed in wet weather or at night.
