    Extasy isn't a morning wake-up call, but it’s worth the 90-minute boat ride from Noumea. It’s got that remote feel, not many boats out here, which we always appreciate. The main event is a proper wall, a real vertical drop that goes down to at least 32 metres, possibly more, and it’s usually humming with activity. You’ll want to drift along, letting the current do some of the work, keeping an eye on the blue for bigger pelagics. We’ve seen grey sharks cruise by here, often just shadows at the edge of visibility, and the occasional eagle ray makes a graceful pass. Closer to the wall, huge gorgonians fan out, sometimes with long-nosed parrotfish nibbling around their bases, and plenty of giant morays peek from crevices. Visibility averages 21m, so you get a good sense of the scale. This spot is best for experienced divers comfortable with a bit of current and ready to explore a less-trodden path. It’s a site for those who appreciate dramatic topography and the chance of a bigger animal encounter.

    Safety Notes

    Overhead environment - never enter without proper cave/cavern training, redundant equipment, and a guideline.
