Watch as many Blue Planet episodes on iPlayer as you like, but there’s nothing like seeing the Great Barrier Reef with your own eyes.
Slipping into the Coral Sea, all you need is a snorkel and mask to gaze at one of the world’s greatest natural wonders, a living structure so huge it can, famously, be seen from space. No PADI required: simply dunk your head in to watch fish brushing past your snorkel, starfish flexing in the sun’s rays, and bright coral rippling in the current like wildflowers in a meadow. If you’re lucky, you might spot a giant clam, a turtle or a reef shark.
