The largest coral reef in the world lies just off the coast of Cairns and offers thousands of kilometres of coral, marine life and untouched white sand beaches.

The Great Barrier Reef is one of the Seven Natural Wonders of the World. It stretches for 1,240 miles (2,000 kilometers) in the warm waters off the coast of North Queensland. The reef is known for its pristine white-sand beaches, secluded islands and crystal-clear waters brimming with coral and marine life. The World Heritage listed site is best visited by day trip from Cairns. Snorkel, dive or cruise the reef on a glass-bottomed boat.

This is the world’s largest coral reef. It encompasses close to 3,000 individual reefs and 900 islands that stretch over almost 133,000 square miles (350,000 square kilometers). It’s estimated to be about 600,000 years old, and is renowned for its stunning biodiversity. See tropical fish, sea turtles, whales, dolphins, porpoises, molluscs and giant clams that are more than 120 years old. Living organisms like sponges and starfish feed off the coral.

The best way to enjoy the reef is to get on a boat and head out to sea. You can organize tours from the central tourism office in Cairns. There are a range of different tour companies and packages to choose from, whether you want to snorkel or dive, charter a yacht or stay overnight on an island. If you prefer to stay dry, sign up for a cruise on a glass-bottomed boat and explore the reef in an underwater observatory.

Many islands make up the Great Barrier Reef, and some are easily reached by day trip from Cairns. The islands range from low-lying sand cays surrounded by crystal-clear water, to popular holiday islands dotted with resorts. Island hop as part of a tour or book a seat on a sea plane and spend a couple of nights in a luxury resort.

June to October is considered peak season when there is the best water conditions and the most number of visitors. Come outside this season for reduced rates on accommodation and tours. The average seawater temperature is 79 F (26 C), and the air temperature is warm in winter and hot in summer.

It takes anywhere between 90 minutes and two hours to reach the reef from Cairns.

"This property is spacious and nicely located along the 4 Mile Beach, but it is not easily walkable to the town nor any restaurants nearby. The facilities/pools seemed like they could use a deep cleaning although our room seemed to be updated and clean. The restaurants on site are quite good."
