    Mirlo. If you're going to dive in the Loyalty Islands, make this one a priority. We love a good channel dive, and Mirlo delivers with serious style. Forty-five minutes out into Bayes Pass, and you're dropping into a world of big fish and even bigger gorgonian fans. We’re talking about faults in the reef so wide you could drive a truck through them, lined with these ancient, purple-red giants. Keep your eyes peeled, because Mirlo is all about the pelagics. Schools of fusiliers are usually so thick they shimmer like liquid silver, parting only for the grey sharks that cruise through. We often see huge jacks and barracudas, sometimes even a tiger shark if you hit it right. The current can be brisk, which keeps the water moving and the visibility hovering around 30 metres, so it’s a site best suited for confident divers comfortable with a drift. You'll spend most of your time mesmerised by the sheer scale of the reef and the density of the schooling fish.
