    Arche aux Gorgonnes, off the Loyalty Islands, is a site we keep coming back to. The arch itself sits at 17 metres, a natural frame for the deeper drop-off, which tumbles past 60 metres. We love to drift along the wall, eyes peeled for grey reef sharks patrolling the blue. The name, ‘Arch of Gorgonians’, is no joke. These soft corals are everywhere, swaying gently in the current, creating a textured backdrop for the schooling fusiliers and triggerfish. Look closely, and you’ll spot parrotfish, particularly the vibrant Schlegel's and the chunky Humpnose unicornfish, munching on the reef. Our favourite moment here is always the swim-through the arch itself – it’s a tight squeeze in places, but worth it for the light play. Visibility here is usually excellent, around 30 metres, making it a dream for wide-angle photography. The site suits divers comfortable with wall dives and a bit of current, though it’s generally manageable. We suggest heading out in the morning; the light is best, and the chances of spotting an eagle ray or even a dugong grazing in the shallower sections feel a little higher.
