Planning a trip to the Great Barrier Reef? Whether you’re dreaming of snorkelling with sea turtles, diving among coral gardens, or simply taking in the reef’s beauty from a boat, this world-famous natural wonder is a must-see. Here's everything you need to know before you go.
Where is the Great Barrier Reef Located?
The Great Barrier Reef stretches over 2,300 kilometres along the Queensland coast in northeastern Australia. It’s made up of over 3,000 individual reef systems and hundreds of islands, making it the largest coral reef system in the world. The most popular access points are Cairns, Port Douglas, and Airlie Beach, all of which offer a range of tours and reef experiences for every type of traveller.
Cairns: A lively, tropical city that serves as the gateway to the northern reef, Cairns is the go-to destination for first-time visitors. You’ll find the widest variety of reef tours here—from half-day snorkelling trips to multi-day diving adventures. It also has a buzzing backpacker scene, a scenic esplanade with a public lagoon, and easy access to other natural attractions like the Atherton Tablelands and Kuranda.
Port Douglas: Just an hour north of Cairns via a stunning coastal drive, Port Douglas is quieter and more upscale, with a laid-back vibe perfect for couples and families. It offers quick access to pristine sections of the outer reef, as well as the ancient Daintree Rainforest, one of the oldest rainforests on Earth. It’s also known for its boutique resorts, local markets, and Four Mile Beach.
Airlie Beach: Situated further south, Airlie Beach is the main launchpad for exploring the breathtaking Whitsunday Islands. This vibrant coastal town is popular with sailing enthusiasts, offering overnight yacht trips, scenic seaplane flights, and snorkelling excursions to remote coral reefs. Don’t miss a visit to Whitehaven Beach, famous for its pure white silica sand and crystal-clear turquoise waters.
Top Things to Do on the Great Barrier Reef
Snorkelling: Ideal for beginners and families; you’ll float above shallow coral gardens filled with colourful fish, anemones, and sometimes green sea turtles or reef sharks.
Scuba Diving: Dive deeper into the reef’s magic with guided tours that explore underwater caves, bommies, and drop-offs teeming with marine life.
Glass-Bottom Boat Tours: A fantastic, accessible option for non-swimmers who still want to witness the reef’s vibrant biodiversity without getting wet.
Helicopter & Seaplane Flights: Take to the skies for a once-in-a-lifetime aerial view of the reef, including the iconic Heart Reef, which is only visible from above.
Sleep on the Reef: Book an overnight stay on a pontoon or liveaboard boat—watch the sunset over the Coral Sea and wake up to sunrise snorkelling in one of the world’s most beautiful locations.
Sailing the Whitsundays: Cruise through a chain of 74 tropical islands, stopping to snorkel secluded bays and lounge on untouched beaches
Best Time to Visit the Great Barrier Reef
The ideal time to visit is between June and October, during the dry season. You’ll enjoy clear visibility for snorkelling and diving, calm waters, and pleasant temperatures. Avoid November to May if you want to skip stinger season (though stinger suits are provided year-round).
Souvenirs & Memories
Bring home reef-inspired keepsakes like locally made jewellery, artwork, or eco-conscious products that support marine protection. Just be sure to avoid buying anything made from coral or shells taken from the reef.
The Great Barrier Reef isn’t just a place — it’s a once-in-a-lifetime experience that connects you with the ocean in the most magical way. Whether you’re exploring vibrant coral gardens or cruising above the waves, this natural wonder deserves a spot on every traveller’s bucket list.
