    StandoutExceptional marine biodiversity

    Corsair Reef sits just a short boat ride from Beau Vallon, a really easy skip out for a relaxed afternoon dive. We love that it’s reliably shallow, topping out around 15 metres, which means plenty of bottom time and lots of light penetration for those corals. You drop onto a mix of sand and reef, and immediately we’re looking for the big schools of fusiliers that seem to constantly patrol the place – they’re thick enough sometimes to feel like a wall of silver. Keep an eye out for the smaller stuff too; we often spot Pale-spotted Combtooth-Blenny peeking out from the coral heads, and there are always Bennett's Pufferfish wobbling around. The table and staghorn corals here are healthy, providing homes for Checkerboard wrasse and juvenile Blue Surgeonfish. While the currents are usually light, we’ve hit it when there's a gentle drift, making it an effortless cruise past the colourful reef. It’s a site that suits anyone looking for a chilled dive with consistent reef activity, without the need for deep or challenging conditions.
