What is the best reef to visit from Cairns?

The Great Barrier Reef consists of 2,900 individual reefs in total and is home to 900 islands. The Cairns region hosts both Outer Reef and Fringing Reefs, the latter of which is a reef situated around an island or off a shoreline, with the Outer Reef being an isolated reef out in the middle of the big blue. During tours leaving from Cairns, you’ll likely head to the Outer Reef, where your tour will take you to ideal snorkelling and diving reefs depending on the day's tides and wind.

Several reefs that are often targeted during the day and overnight trips from Cairns are Michaelmas Reef, Oyster Reef, Upolu Reef and Arlington Reef, to name a few. Each of these reefs is made up of unique coral formations, which are bordered by sand,  seagrass and open ocean. Different sites have a wide variety of marine life, full of soft and hard corals, thousands of species of fish, turtles, reef sharks and other amazing and unique sea creatures. Some sites are ideal for snorkellers, with shallow reefs, while others are ideal for scuba divers with deeper reefs and coral formations. Many tours target reefs that are a good combination of both, allowing them to accommodate both types of ocean explorers.
