Snorkeling the Great Barrier Reef, Australia

Snorkeling the Great Barrier Reef.

The Great Barrier Reef & Queensland

The Great Barrier Reef is the largest living structure on earth, a 1,400-mile mosaic of coral that runs the length of the Queensland coast and the only living thing visible from space. It is one of the seven natural wonders of the world, and for most travelers it is the single image that draws them to Australia in the first place. Out on the water the scale is hard to take in: ribbon reefs, coral cays and turquoise lagoons stretch beyond the horizon in every direction, and beneath the surface lies a world of color and life unlike anywhere else on the planet.

The magic, of course, is below the waterline. Slip on a mask and you drop into a garden of coral in a hundred shapes and shades, alive with movement. Green sea turtles glide past at arm's length, reef sharks patrol the deeper channels, rays drift over the sand, and thousands of fish in every imaginable color school around the coral heads. You do not need to be a diver to see it; a good snorkel over a shallow reef puts the whole spectacle right beneath you, and certified divers can drop deeper into the canyons and swim-throughs of the outer reef.

We reach the reef in a few different ways, and we match the approach to the trip. From Cairns or the relaxed town of Port Douglas, fast boats run out to the outer reef for a day among the coral, or a few nights on an island in the Whitsundays puts you steps from the water and within reach of the famous swirl of white sand at Whitehaven Beach. For a view no boat can give you, a scenic flight lifts off over the reef and reveals the perfect natural shape of Heart Reef from above, a fitting finale to a day on one of the wonders of the world.

Whitehaven Beach & the Whitsundays

The Whitsunday islands sit right on the reef, fringed by coral and home to Whitehaven Beach, four miles of pure silica sand swirled into turquoise shallows.

Know before you go

The practical details.

When to go

Good to know

When to go

The dry season, June to October, brings the clearest water and the calmest seas, so visibility is excellent and it overlaps with the mild, sunny months on land. Box jellyfish season runs November to May, when stinger suits are provided for inshore swims.

How to visit

Good to know

How to visit

Day boats run out to the outer reef from Cairns and Port Douglas, while a stay on a Whitsunday island puts you closer to the coral for longer. Pontoons, glass-bottom boats and semi-submersibles mean non-swimmers can see the reef too.

Reef-friendly travel

Good to know

Reef-friendly travel

The reef is fragile and protected, so we choose eco-certified operators, ask travelers to use reef-safe sunscreen and never touch the coral. A marine biologist-guided tour is a wonderful way to understand what you are seeing.
