Snorkelling on the Great Barrier Reef is one of the most incredible experiences a person can enjoy. With much of the reef's colour and marine life visible within a couple of metres of the water's surface, snorkelling offers all swimmers, regardless of their skill level, the opportunity to see this diverse eco-system up close. Float effortlessly over rich, colourful coral gardens teeming with life from the cute and playful clownfish to the graceful beauty of the green turtle. Giant clams, stingrays, maori wrasse, cods and colourful parrotfish, are just some of the hundreds of species you will encounter during your visit to Opal Reef with Calypso. Proudly locally owned and operated, Calypso Reef Cruises has dedicated snorkel vessels to visit the outer Great Barrier Reef and with three fantastic sites to explore, you will be busy for hours.
