The largest coral reef system on the planet is Australia’s top tourism treasure, the World Heritage-listed Great Barrier Reef. The reef stretches over 2,300 kilometers from Queensland’s northern tip to Bundaberg’s coastal town, and it is one of the world’s most diverse ecosystems. It is the only living structure visible from space, so vast is this complex of reefs, islands, coral cays, seagrass beds, and mangroves.

A top Australian outdoor adventure is to experience the Great Barrier Reef. Some of the most popular things to do include SCUBA diving and snorkeling along the shimmering coral reefs, sailing around idyllic tropical islands, fishing in designated zones, peering from a glass-bottomed boat at the abundant marine life, and soaring on a scenic flight over this magnificent natural wonder.

You can access the Great Barrier Reef from various points along the Queensland coast, thanks to its vast size. The thriving tourist town of Cairns in Far North Queensland is one of the most popular launching points for reef adventures. Port Douglas, about an hour’s drive north of Cairns, is a smaller and more tranquil base for reef trips. It’s also the shortest distance from the Great Barrier Reef to the mainland.

Warming ocean temperatures are causing the large-scale coral die-off, especially along the reef’s far northern stretches, so try to see this magnificent spectacle as soon as possible. With the hope of preserving this important resource for future generations, the Australian Government has recently introduced a long-term sustainability plan to help combat the effects of climate change and pollution.

1. Great Barrier Reef Marine Park

The Great Barrier Reef Marine Park, which covers more than 344,000 square kilometers (half the size of Texas), was established in 1975 to protect the reef’s fragile ecosystems. There are over 2,900 coral reefs, 600 continental islands, 300 coral cays, seagrass beds, and numerous mangrove islands within its borders. An astonishing range of marine life is also protected by the park. More than 600 species of hard and soft corals range from brain coral bulbous spheres to craggy staghorn and graceful sea fans of gorgonians. Mollusks such as giant clams and more than 1,625 species of fish live in these thriving underwater jungles. You can spot sharks, rays, sea snakes, dugongs, turtles, dolphins, and whales in the surrounding waters.

The park is a protected area of mixed-use which allows sustainable fishing in designated areas, unlike some others in marine reserves. In consultation with the Aboriginal and Torres Strait Islanders, whose heritage is closely linked with the region, the Great Barrier Reef Marine Authority administers the park. They work together to safeguard this diverse patchwork of fragile ecosystems and incredible biodiversity.

2. Whitsunday Islands

The Whitsunday Group’s 74 tropical islands, which are strung along the Great Barrier Reef, make excellent bases for discovering the reef’s wonders. Six national parks protect their fragile ecosystems, and eco retreats, campsites, and luxury resorts are home to several. You can sign up for a snorkeling or SCUBA diving trip, enjoy a cruise, or hop on board a sailboat to explore the reef from these sun-splashed shores.

Sight-seeing cruises frequently visit some of the top beaches in the world, like the sublime Whitehaven Beach on Whitsunday Island, as well as the fish-rich snorkeling reefs. Heron Island has some of the best diving of all the Whitsunday Islands, while Hamilton Island has a wide range of accommodations, from mid-range Whitsunday Apartments to the opulent Qualia Resort, and is the only Whitsunday Island with a large jet airport. Luxury travelers flock to Hayman Island, which is home to One&Only, a five-star nature resort, while families flock to Daydream Island and Long Island. On the Whitsunday and Hook Islands, national park campsites are available if you plan on camping. The principal gateways for Whitsunday sightseeing are Airlie Beach and Shute Harbour. Ferries, luxury yachts, helicopters, and seaplanes can take you to your dream island from here.

3. Whitehaven Beach

Whitehaven Beach on Whitsunday Island is often classified as one of the world’s top ten beaches and has a splendid seven-km stretch of white silica sand and vibrant blue sea. On day trips on a luxury yacht, ferries, motorboats, or sailboats you can visit the beach, and Tongue Bay is a favorite bareboat anchorage. Through the island, walking paths lead. A 10- to 15-minute walk from the beach to Hill Inlet is a popular destination for spectacular views over the white hills and turquoise waters. You can book a scenic flight and soar over the marbled seascape on an airplane if you don’t have time to walk on the soft sands. South of the beach camping is allowed.

4. SCUBA Diving & Snorkeling

One of the most desirable diving destinations in the world is the Great Barrier Reef. More than 2,900 reefs with kaleidoscopic walls, spectacular coral channels, swimming pinnacles are located in this wonderful underwater land. Gliding across 90-meter drop-offs off the edge of the continental shelf can feel like flying over an underwater jungle.

Other wildlife attractions include the North Horn Shark Food Frenzy; Cod Hole with its gigantic Potato Cod near Lizard Island; Osprey reef Drift Dives; Lighthouse Bommie Migrating Minke Wales; Agincourt Ribbon reefs, easily accessible from Cairns; and Flynn Reef Coral Gardens.

Heron Island provides some of the best dive experiences on all of its islands in the Whitsunday Islands, including a manta-ray cleaning station on the Heron Island.

Along the reef, wreck diving is also possible. The SS Yongala, a steel and timber steamship that sank in 1911 during a cyclone and killed 121 people, can be visited from Townsville or Magnetic Island.

Day tours are an excellent way to taste the reef while diving in water diving offers maximum time and opportunities to visit some of the most remote and less-visited reefs.

If you’re staying in Cairns, the Great Barrier Reef Diving and Snorkeling Cruise from Cairns is a great way to see the spectacular underwater scenery. This full-day trip involves comfortable boat transportation, barbecue lunch, snorkeling stops, and optional SCUBA diving and helicopter flight upgrades.

5. Reef Cruises and Sailing Adventures
