Things To Do in The Great Barrier Reef

When you cruise to the Great Barrier Reef with Carnival, the destination isn’t the only highlight of the journey. Here are all the not-to-miss highlights.Without doubt, the Great Barrier Reef is one of the world’s most spectacular natural attractions.

Here are seven unmissable highlights of our cruises to one of the Seven Natural Wonders of the world, the Great Barrier Reef. Please note, ports of call and their order vary – below is indicative only.

We can’t think of a better way of getting to the reef than on a cruise. It might be the ultimate destination on our six- to 10-day cruises from Sydney and Brisbane, but there’s so much to see and do before you even get there.

Choosing to explore with Carnival means the excitement begins the moment you step on deck. You might spend your morning lounging by the pool or preparing for a day of snorkelling among the colourful marine life that calls these reefs home. These itineraries create a seamless holiday where you can easily enjoy all your favourite things to do in the Great Barrier Reef while relaxing in total comfort.

Water activities for guests

Bay watch at Tangalooma, Moreton Island

Most of our Great Barrier Reef cruises call at Tangalooma on Moreton Island. Nothing will quite prepare you for how beautiful this little-known treasure of Brisbane’s Moreton Bay actually is. Beyond the ultra-white sand and impossibly crystalline waters, the island is also a marine sanctuary and home to the Tangalooma Wrecks, a haven for snorkellers.

The famous Tangalooma Wrecks sit close to shore, with shallow depths and excellent visibility. Colourful fish weave through sunken ships, offering an underwater playground that suits all confidence levels. Evening dolphin feeding adds a magical wildlife moment that sets the tone for the journey ahead.

Beginner-friendly snorkelling on the Great Barrier Reef

Snorkelling ranks high on the list of things to do in the Great Barrier Reef and Carnival shore excursions make the experience easy and stress-free. Guided tours include safety briefings, flotation aids, and quality snorkel gear, helping first timers feel comfortable straight away.

Outer reef locations usually deliver clearer water and vibrant coral gardens. Marine life often includes clownfish, parrotfish, turtles, and reef sharks cruising calmly nearby. Semi-submersible boats and glass-bottom tours ensure non-swimmers still enjoy the reef action without getting wet.

Outer reef experiences from Port Douglas

Port Douglas is the only place in the world where two World Heritage sites, the reef and the Daintree rainforest, meet. For a close-up look at the big blue sea, book a shore excursion* and take a fast catamaran to Agincourt Pontoon in the Outer Reef, where you can swim, snorkel and hop aboard a semi-submersible vessel for a view you won’t forget in a hurry.

The well-organised reef platform features structured facilities that suit families, older travellers, and anyone keen to enjoy reef life with minimal effort. Snorkelling, swimming, underwater observatories, and semi-submersible tours all operate from one central base, while many guests also pair reef time with a Daintree Rainforest visit for a contrasting nature experience that showcases the area’s incredible biodiversity.

High-adrenaline water adventures in Cairns

For adrenaline junkies, Cairns also offers endless opportunities to get the pulse racing, while giving you access to some of the region’s most spectacular sights. Book a shore excursion* and explore the Goldsborough Valley’s Mulgrave River on our Wild River Tube Ride; take a Bad Fishy Jet Boat ride on the Trinity Inlet; or jump on a bike and explore Cairns on two wheels.

River tubing through lush rainforest scenery combines gentle rapids with refreshing fun for active travellers, while jet boat rides deliver high-speed spins and splash-filled thrills through mangrove-lined waterways. These water-based adventures cater to thrill seekers yet remain accessible for mixed-age groups, blending excitement with the natural beauty of the region.

Above-water experiences

Scenic flights over Cairns and the reef

Once you’re in Cairns, the wonders of the Great Barrier Reef are on your doorstep. And one of the best ways to take in the reef’s magnitude is from the air. On a 40-minute scenic flight, you’ll take in the incredible colours and shapes of the reef before flying back towards the mainland, passing over Green Island, Arlington Reef and Palm Cove.

The experience reveals the vast mosaic of blues and greens stretching across the horizon, adding wonderful context to any snorkelling or reef tours and helping travellers appreciate the sheer scale and beauty of this natural wonder. It suits all ages and provides breathtaking aerial views that make the reef’s majesty even more memorable.

Island escapes in the Whitsundays

Airlie Beach, on the central Queensland coast, is a beautiful port town and a gateway to the state’s sublime Whitsunday Islands, including one of the largest: the uninhabited Whitehaven. On our Exhilarating Whitehaven Expedition, take a wild ride on an inflatable boat to the isle, home to Whitehaven Beach, which has some of the whitest sand in the world. Swim, walk and enjoy lunch before returning to your cruise ship for an evening of entertainment galore.

Fast boat rides across turquoise water led to time spent swimming or strolling along the shoreline, with shallow waters that suit families and a postcard-perfect setting that couples love to soak up. The silica sand, so bright it almost glows, invites barefoot wandering, creating relaxed moments amid stunning island scenery.

Dining delights onboard a Carnival cruise ship

While the natural world shows off all of its beauty outside, inside our chefs are creating great food to tempt you. Indulge your tastebuds at fabulous eateries like Masala Tiger^, the Pizzeria, Guy’s Burger Joint^ and Swirls. Or elevate your culinary experiences by visiting one of our specialty restaurants*. Try melt-in-the-mouth steak at Fahrenheit 555, Japanese deliciousness at Bonsai Sushi Express~ or book a seat at the very special Chef’s Table

Between ports, onboard dining becomes a highlight with casual venues serving crowd favourites like burgers, pizza, and soft serve, while specialty options give every night a different flavour. Shared meals spark laughter and storytelling, adding to the relaxed cruise vibe and turning evenings into celebrations of the day’s adventures.

Entertainment and activities at sea

In between marvelling at Australia’s incredible coastline, you might also find yourself marvelling at some of the incredible offerings on board the ship. That might include enjoying one of our dazzling, original musical productions or stage shows; laughing till your sides hurt at The Punchliner Comedy Club; or showing the world what you’re made of at karaoke.

Live theatre shows, musical productions, and comedy nights light up evenings onboard, while karaoke sessions, games, and family-friendly activities create a social buzz across the ship. Sea days feel just as memorable as port days, keeping energy high from start to finish.
