Why dive here
With 116+ marine species recorded in the area - including dugongs, eagle rays, great white sharks, manta rays and mobula rays (devil rays) - Carouso Mio offers some of Loyalty Islands's richest drift diving. Water ranges 24-28°C, warmest January, February, March.
Flat Rock, especially that Turtle Cave, is one of those Sydney sites we keep coming back to. Forget what you might hear about tricky shore entries elsewhere; this one is surprisingly manageable, though a boat dive means less huffing. We usually drop in and drift, letting the water carry us through the cave. It’s not a deep dive, around 10 metres inside, but it’s packed. Light filters in, making the resident schools of yellowtail kingfish and bullseye glitter. We've seen banjo sharks tucked into crevices, and a lazy Port Jackson or two often cruises past. The cave itself is more of a swim-through, wide enough you don't feel squeezed, and the rock formations are interesting enough on their own. Our advice? Go on a calm day; the visibility really pops then, often pushing 15 metres. It’s a site that suits pretty much everyone, even newer divers, as long as you respect the surge if it’s running.
