But with 348,700 square kilometres of this natural wonder to explore, it can be hard to know exactly where to start. Wondering where the best place to snorkel is? What about the best time of year? And what exotic marine wonders should you keeping an eye out for? This Cairns Snorkelling Guide will ensure that you experience the very best that the Great Barrier Reef has to offer.
Due to the exotic tropical climate, Cairns is great for snorkelling all year round! With water temperatures varying from 29 to 23 degrees Celsius, Cairns snorkelling is a comfortable, enjoyable experience no matter what month of the year you decide to dive in!
Unlike southern cities in Australia, Cairns does not have four specific seasons. The climate in Cairns is generally separated into two seasons; wet season, which runs from November to March, and dry season, which runs from April to November. Advantages of snorkelling in the wet season include warmer water temperatures. On the other hand, advantages of snorkelling off Cairns in the dry season include the chance of spotting Minke and Humpback whales.
Guests regularly spot Green Sea Turtles on our Moore Reef full day tour, however, the Great Barrier Reef turtle mating season allows snorkellers to see turtles interact with each other on a whole different level.
Turtle nesting season typically begins in November and is in full swing by December. Turtle hatching season takes place in February and March. Breeding season runs over this whole period and snorkellers can catch a glipse of Green Sea Turtles' unique courting techniques. Look out for males nuzzling female's heads or nibbling on their flippers.
Snorkelling with whales should be on every marine life lover's bucketlist! The Great Barrier Reef off Cairns is annually visited by Minke and Humpback whales who are making their annual migration from the Antarctic to the tropical waters of the Great Barrier Reef.
The Minke whale season runs from late May to September, with Humpback whales following in tow from July to August.
The Outer Great Barrier Reef is undoubtedly the best place to snorkel off Cairns. As a matter of fact, the Outer Barrier Reef off Cairns is home to some of the most pristine coral on the entire reef.
These vibrant coral gardens are located close to the Continental shelf of Australia and are known for their colourful hard corals, incredible visibility and abundance of fish and marine life. Due to it's position on the Continental shelf, the Outer Barrier Reef is home to staggering coral drop offs that can drop hundreds of metres below sea level.
Sunlover Reef Cruises's Moore Reef Marine Base is surrounded by some of the best quality coral in Far North Queensland. Best of all, the coral is located just a few metres off our easily accessible snorkel Marine Base, making it perfect for swimmers of all abilities.
Our designated snorkelling area is 300 square metres in size and is home to hundreds of marine life species. This includes a variety of colourful soft corals, as well as hard corals including staghorn coral, brain coral and boulder coral.
With a shallow depth of 1-4 metres and unbeatable visibility, there's no need to worry if you don't want to dive! There's a kaleidoscope of coral and hundreds of fish to be spotted just by snorkelling. Tick an abundance of iconic Aussie marine species off your must-see list including "Nemo", sea turtles, giant clams and more! You can even befriend, "Wally", our friendly and goofy resident Maori Wrasse!
If you are after a soft coral ecosystem, our Arlington Reef Marine Base is just what you've been looking for! This unique, horse-shoe shaped reef is only accessible via Sunlover and is a stunning rainbow of soft corals and anenomes. Home to an array of giant clams, anenomefish and colourful molluscs, this unique ecosystem also offers regular manta ray sightings.
There's a rainbow of fish to look out for on your Cairns snorkelling adventure! We recommend keeping an eye out for these adorable Aussie icons...
If there's one celebrity on the Great Barrier Reef, it's the Clownfish! After soaring to international fame in Disney's "Finding Nemo" this small and colourful fish is sure to give you literal heart eyes. These little guys live in anemones and have a symbiotic relationship with their homes. The Clownfish uses the anemone's venomous tentacles to protect itself from predators, whilst the anemone benefits by the increased circulation of water. The Clownfish also removes the anemone's dead tentacles.
Maori Wrasse may be some of the larger fish on the Great Barrier Reef, however they are nothing to be feared!
As a matter of fact, our resident Maori Wrasse, "Wally", is perhaps the friendliest fish on the Great Barrier Reef. This gentle giant loves being the centre of attention and befriends Sunlover's snorkellers, divers and seawalkers on a daily basis.
The giant clam is the largest bivalve mollusc and can grow to a whopping 500lbs in weight! Clams survive by their symbiotic relationship with the algae that live in their tissues, which provide nutritious sugars and protein for consumption.
There's nothing more relaxing than hearing Parrotfish crunching on coral underwater! These colourful critters use their 'beaks' to break down dead coral, which they then consume and convert into sand.
There are 30 different types of Parrotfish on the Great Barrier Reef and you can spot a rainbow of them on our hard coral at Moore Reef.
From small spotted sting rays, to large majestic manta rays, a ray flying gracefully over the Great Barrier Reef is always a wonderful sight to behold.
With hundreds of marine species to spot, your Cairns snorkelling experience is sure to leave you with memories to last a life time...
