Grande Terre and Camp grounds

Hi guys, 2 questions about my upcoming trip to New Caledonia

Is this a good itinerary for exploring Grande Terre:
Noumea to Parc de la Riviere Bleue
Parc de la Riviere Bleue
Parc de la Riviere Bleue to Bourail
Bourail to Poum
Poum to Hienghiene
Hienghiene
Hienghiene to Noumea airport

I will also be spending some time on the Isle of Pines. Can anyone recommend camping grounds on both the Isle of Pines and the places on Grande Terre mentioned above? I've heard good things about Roller Bay on the Isle of Pines.

Thanks!

There are several attractive campsites just outside Hienghiene, but camping is no longer allowed in the Riviere Bleue park itself.
Your itinerary looks great.
