Great Barrier Reef Cruises

This classic 8-day Australia small ship cruise uncovers the secrets of the Great Barrier Reef—an incredible underwater world hidden just beneath the water’s surface. Whether you experience the reef by glass-bottom boat, snorkeling or diving, it is a mystical world filled with coral, marine life and vibrant tropical fish. The informative crew will always be on hand to provide assistance and information about the fascinating reef life and habitat. An experienced dive instructor will also be there to support the exhilarating experience of scuba diving around the Great Barrier Reef.  

Discover a paradise of remote and uninhabited islands. Become a relaxed beachcomber or an inquisitive adventurer. The starkness of the remote and unique coral cays will fascinate you. Go snorkeling and coral viewing among teeming fish life on pristine outer reefs and exclusive mooring destinations, offering a unique and unmatched experience of the Reef, all abundant with marine life and dancing corals.

In Cairns, take time to independently explore the city. Discover Cooktown’s fascinating historical museum, offering artifacts including the original anchor and cannon that was jettisoned overboard after Captain James Cook’s ship Endeavour struck a reef and began taking on water. Or visit the Botanic Gardens, where you may catch a glimpse of native Australian wildlife including kangaroos and wallabies. Top off the adventure with a stop on a private island for special sunset drinks.

Special Citizen Science on The Great Barrier Reef themed departures offer a conservation focus with opportunities to meet with researchers, learn about conservation work and participate in citizen science projects. These departures feature their own unique routes; contact an Adventure Specialist for details.

Board the 72-guest Coral Discoverer for your 8-day Great Barrier Reef small ship cruise and enjoy one of the most comprehensive reef tours in Australia. This expedition ship offers an onboard atmosphere of Australian hospitality, with stylish furnishings, generous public spaces and updated technology. Appreciate opportunities to kayak; snorkel; and cruise in a Zodiac, glass-bottom boat or the ship’s special Xplorer tender.

Days 2 - 7
Great Barrier Reef Exploration

No two Great Barrier Reef cruises are the same. Each expedition is crafted by experienced captains and expedition leaders around weather and sea conditions. Below is a selection of the key destinations visited.

Fitzroy Island

At Fitzroy Island, enjoy a walk through the Secret Garden rainforest or for the more adventurous, a walk to the de-commissioned lighthouse rewards hikers with panoramic views of Coral Sea, islands and mainland mountain ranges. Snorkel over the fringing reef, relax on the beach and lend a hand to the volunteers while learning about the turtles at the Cairns Turtle Rehabilitation Center, where sick and injured turtles are cared for before being returned to the wild.

Sudbury Cay

Arrive at Sudbury Cay, a tiny sand cay that barely rises above the Coral Sea. Far removed from the bustle of civilization, slip off your shoes and feel the sand between your toes as the tropical waters of the Coral Sea lap gently against the shoreline. Surrounded by glistening sea and bathed in the glow of twilight, enjoy sundowner drinks and the company of like-minded explorers while relaxing and watching the sun gently sink below the horizon.

Mackay Reef & Cay

Enjoy more spectacular diving and snorkelling opportunities at Mackay Reef, where we look for green sea turtles and explore the vibrant coral gardens.

Cooktown

In historic Cooktown, learn the history of the Guugu Yimithirr, the first people of this ancient country. Discover recent European history with a visit to the site where Lt. James Cook beached HMB Endeavour to effect repairs in 1770. Wander through the rare flora collection at the Botanic Gardens and visit James Cook Museum, where the story of Cook’s landing is told from an Aboriginal perspective and where artifacts are on display. Later, cruise towards Lizard Island, arriving in time for sunset.

Lizard Island

Hike to the summit of Cook’s Look and enjoy the same view Lt. James Cook did when searching for safe passage through the maze of coral reefs. Snorkel over giant clam gardens from the beach at Watson’s Bay, relax on the white-sand beach beneath shady oak trees and learn about the tragic story surrounding Mary Watson. There may be an opportunity to visit Lizard Island Research Station, operated by the Australian Museum to facilitate coral reef research and education on the Great Barrier Reef.

Osprey Reef

Remote Osprey Reef is the summit of a 6,560-foot undersea mountain located beyond the continental shelf. Enjoy amazing underwater visibility and observe magnificent corals, plummeting drop-offs and many fish in the crystalline waters. Osprey Reef is a highly prized tropical dive location amongst scuba divers, called an ‘oasis for living creatures of all kinds’ by Sir David Attenborough. Osprey Reef is a true expedition-style destination and this visit is subject to appropriate weather conditions.

Ribbon Reefs

The Ribbon Reefs are a line of outer coral reefs on the edge of the continental shelf and are renowned for their prolific marine life and extensive coral species. Enjoy the rare opportunity to snorkel and dive over these excellent reefs, a favorite for its wide variety of marine life and pinnacles cloaked in coral. Join a guided snorkel tour led by the expedition team and witness this extraordinary ecosystem up close. These northern reefs are renowned for spotting iconic marine species such as potato cod, wrasse, sharks and turtles.
