    StandoutExceptional marine biodiversity

    Conception Rocks is our kind of drift dive. You’re dropped in, usually into a decent current, and the boat waits for you downstream. We love that feeling of just letting go and flying past the granite boulders, watching the reef unfold. It's a real playground for bigger pelagics, with plenty of Indian scad and even a chance for whale sharks during the right season. The site maxes out around 22 metres, but you'll spend most of your time shallower, perhaps 15-18m, riding the surge and peeking into crevices. Keep an eye out for the blue-spotted stingrays resting in the sand patches between the rocks, or a sleepy goby trying its best to blend in. We’ve also spotted ghost pipefish here, clinging to the gorgonians, so it’s not all about the big stuff. The currents here can be robust, so it’s best for confident divers who enjoy a bit of a ride. Expect a dynamic dive, full of movement, with white tip and black tip sharks often cruising the edges of visibility.
