How to get to Green Island from Cairns

Green Island sits just 27 kilometres off the Cairns coastline – close enough that you can see the mainland from the beach, yet far enough out that the water shifts to that clear reef blue during the crossing. Getting there is one of the easiest parts of any Cairns holiday, […]

Your complete introduction to diving at the Great Barrier Reef: everything you need to know

Snorkelling the Great Barrier Reef is one thing. Dropping below the surface on scuba, leaving the world above behind and breathing through a regulator while coral formations rise around you, is something else entirely. An introductory dive, sometimes called a resort dive or discover scuba dive, lets you do exactly […]

Colorful coral reef ecosystem at the Great Barrier Reef with diverse marine life

Great Barrier Reef conservation and protection: how to visit responsibly

The Great Barrier Reef is the world’s largest coral reef system, a World Heritage-listed ecosystem, and one of the most closely studied marine environments on the planet. It’s also under real pressure – from warming oceans, bleaching events, and a range of threats that don’t pause between tourist seasons. Anyone […]

How to take great photos underwater at the Great Barrier Reef

You’ve planned the trip, booked the tour, and found yourself floating above a coral formation with a turtle drifting past two metres below – and the photo you take looks grey, blurry, and nothing like what your eyes just saw. The Great Barrier Reef is visually extraordinary, but underwater photography […]

Great Barrier Reef marine life guide: meet the world below the surface

Put your face in the water at the right outer reef site on a clear Cairns morning, and the first thing that hits you is the scale of it. The Great Barrier Reef is home to more than 1,600 species of fish, 600 types of coral, six of the world’s […]

What to expect on a Great Barrier Reef tour from Cairns

Most people spend weeks or months looking forward to their reef day. Then the morning arrives, and somewhere between packing the bag and finding the dock, the questions start. How long is the boat ride? What do they actually do when they get there? Is lunch included? What if the […]

Great Barrier Reef safety tips  

Most people spend months looking forward to their reef day – and then spend the actual morning in a mild panic, wondering whether they’ve forgotten something important. The good news is that reef tours from Cairns are genuinely well-run, the crew are experienced, and the Great Barrier Reef is far […]

First-time Great Barrier Reef visitor guide

There’s a moment – usually about thirty seconds after you put your face in the water – when it hits you. The coral is right there. Not in a documentary, not behind glass. Just there, in every colour, with fish weaving through it like they have no idea you’re watching. […]

Great Barrier Reef snorkelling vs diving 

You’re on the boat, the water is that ridiculous shade of blue you only see in photos, and someone hands you a mask. Now comes the question most first-timers wrestle with: do you float along the surface and snorkel, or strap on a tank and drop below? It’s one of […]

Snorkelling gear including fins and mask for a Great Barrier Reef tour packing list

What to pack for a Great Barrier Reef tour

Packing for a Great Barrier Reef tour is one of those things that takes ten minutes to get right and costs you a whole day if you don’t. There’s a particular kind of regret that hits when you’re an hour offshore and realise you’ve left the reef-safe sunscreen at the […]

How much does a Great Barrier Reef tour cost?

Great Barrier Reef tour prices from Cairns can range from a relatively modest island day trip to a premium outer reef experience with diving and a scenic helicopter flight. That’s a wide range, and working out where your trip sits – and whether it’s worth spending more – is exactly […]

Best time to visit the Great Barrier Reef

The Great Barrier Reef is one of those destinations that looks spectacular in photos taken in every month of the year, and the reality lives up to it. But the experience you’ll have in July is genuinely different from the one you’d have in January, and understanding those differences is […]

We had such a fun time on a half day tour of Fitzroy island with Cairns Discovery Tours! We managed to do an everything we wanted (Nudey beach, long snorkel and lunch) within the time period we had and we even got to swim with turtles 🐢 an unforgettable experience! This would not have been possible without the fantastic help of Maryanne who booked us in for the tour. She went above and beyond to help us find somewhere to leave our bags during our tour and we wouldn’t have been able to go without her help. We enjoyed the experience so much and we are very grateful to Maryanne for her help and her exceptional customer service! I would definitely recommend booking local for these kind of experiences because that kind of customer care just doesn’t come when you book through third party sites. 10/10 experience ⭐️⭐️⭐️⭐️⭐️

We went on a tour with Discovery Tours today, doing the Mossman Gorge, Daintree / Daintree River Cruise, finishing of visiting Cape Tribulation… Our driver was James, who was exceptional. Giving running commentary along the trip. Guiding his group of people through all the different areas. Thanks James, top job.

In June I came to Cairns on holiday from the UK. It was the biggest holiday I've ever taken and because my health limits what I can do took a lot of planning. Maryanne at Cairns Discovery Tours was brilliant. She helped me choose suitable trips, gave me additional information so I could be prepared, advised on the easiest way to get to the departure point for those trips that don't pick up from my accommodation, etc. I booked all my trips except one with Maryanne. Her knowledge of Cairns was invaluable to me. She spoke to me on Whatsapp to answer my questions (we had to arrange call in advance because of the time difference) and when it occurred to me quite close to departure date that I'd need a way of protecting my head and neck from the sun when snorkelling Maryanne got me a suitable headscarf and dropped it off at my accommodation ahead of my arrival. When a friend decided to join me on some of the trips Maryanne was really helpful to her as well. If I am able to come back to Cairns I'll book as much as I can with Maryanne and Cairns Discovery Tours. The service couldn't be bettered.

We have just done the 3 day/2 night Cooktown and Cape Tribulation Tour with 2 friends. An unbelievable experience due to our fantastic guide Steve, who had so much local knowledge on everywhere we visited, especially historical info on the Palmer River gold rush in the 1800s, and Daintree Rainforest botany. Steve was such a good raconteur with friendly personality, who went out of his way to make our trip so enjoyable. Accomodation at both Cooktown and Cape Tribulation was excellent, with amazing setting of the cabins at Cape Tribulation in the rainforest right by the beach. Everything advertised for the tour and more was an memorable experience. Thank you so much Steve!

I was delighted with the Kuranda tour arranged by this company. The timings worked excellently and it was an eminently well organised tour. The train trip up to Kuranda was great fun and fascinating. Personally, I was particularly interested in the engineering. We had an hour in Kuranda Village, which was enough for me, although I expect some people would have liked to have seen the village and visited the butterfly world, which I think would have been tight. Rainforestation was great, plenty of activity of a variety of natures. I could not throw a boomerang to save my life, but it was fun to try. Then the bus down to Cairns was efficient and friendly, with a superb guide.
