Two things which are impossibly green

The first is the entrance to a cave, if you happen to be unfortunate enough to be wandering above for us it was the cliffs as we entered the cave which is on the Isle of Pines in New Caledonia.

The second is a path we followed to get to said cave, I mean how can anything look this green, this other-worldly and yet be a couple of hundred metres from a car park?
