    StandoutExceptional marine biodiversity

    River of Sands is one of those sites we always recommend, especially if you’re looking for something a bit different than the usual wall dive. It’s got this incredible sandy slope that funnels down, carving what really does look like a river in the seabed, all the way to a main drop-off. We love swimming through those narrow channels, following the sand, often spotting razor fish darting back into their burrows as you pass. The topography here is the real star – a fascinating mix of sunlit sections and these darker, hidden gaps along the wall, full of overhangs and ledges. We've found everything from tiny Blackfin Blennies perched on coral to robust Boulder Brain Corals on the shallower bits. The deeper sections often hold some interesting Angelfish and Yellowtail Parrotfish. It’s a sheltered spot too, so currents are usually mellow, making it a great place to really take your time and explore those nooks and crannies. If you enjoy intricate reef architecture and hunting for smaller, more camouflaged critters, this site is a standout.
