Most people fly into Cairns, spend a day on the Outer Great Barrier Reef, and fly out feeling like they’ve done it. And honestly, the reef alone is worth the trip. But here’s the thing about Cairns: it sits at the doorstep of not one, but two UNESCO World Heritage sites, the Great Barrier Reef and the Wet Tropics rainforest, and most visitors only tick off one of them.
In this guide, we’re breaking down how to pair your Outer Great Barrier Reef tours with some of the other iconic experiences in Cairns, from a scenic helicopter flight over the coral to a gondola ride through ancient rainforest canopy to a full day out in the Daintree Rainforest. Whether you have one day or three, there’s a combination here that fits. Consider this your cheat sheet for getting the most out of one of Australia’s most experience-rich destinations.
The Outer Great Barrier Reef: Where Every Cairns Trip Begins
There’s a reason the Great Barrier Reef sits on almost every Australian itinerary. Stretching over 2,300 km along the Queensland coast, it’s the largest coral reef system on the planet and one of the most biodiverse marine environments in the world. From Cairns, you’re perfectly positioned to access it.
The Outer Reef is where you want to be. Clearer water, more vibrant coral, and a greater variety of marine life than the inner reef closer to shore. Think reef sharks, sea turtles, rays and coral gardens in colours that don’t look entirely real until you’re floating above them. Most of the typical Outer Great Barrier Reef tours in Cairns depart in the morning and return by late afternoon, with snorkelling included as standard and scuba diving available as an add-on. This is your Cairns anchor. Everything else builds around it.
1 Day In Cairns: Reef + Scenic Helicopter Flight
If you’ve only got a day in Cairns, this is the combination to go for. Snorkelling the reef gives you one perspective. Seeing it from a helicopter gives you an entirely different perspective and the two together make for a pretty unbeatable day.
From the water, you’re focused on what’s right in front of you: the coral, the fish, the strange and wonderful world a few metres below the surface. From the air, its scale hits differently. The patchwork of reef, the shifting blues and greens of the water, the sheer size of what you’ve just been swimming through. It’s the kind of view that reframes the whole experience.
Why it works: You’ve seen the reef from below. Now see it from above. Same reef, completely different experience. Most operators offer combo packages that bundle the cruise and helicopter flight together, so you’re not juggling two separate bookings. Some even do it in a half day, with lunch and wine on the way back. Either way, you get two bucket list moments sorted in one go.
2 Days In Cairns: Reef + Skyrail & Kuranda Scenic Rail
If you’ve got two days, you’re in a great position. Spend day one on the outer reef, and save day two for the Skyrail Rainforest Cableway and the village of Kuranda. The Great Barrier Reef and the Wet Tropics rainforest are both UNESCO World Heritage-listed, and you can experience both without leaving the region.
It starts at Smithfield terminal, where you board the gondola and glide above one of the oldest rainforests on Earth. The views over the Wet Tropics canopy are the kind that make you put your phone down and just look.
At the top is Kuranda, a laid-back village with markets, wildlife attractions, and cafes where you can spend up to three and a half hours exploring at your own pace. The journey back to Cairns is on the historic Kuranda Scenic Railway, winding through Barron Gorge National Park past hand-carved tunnels, waterfalls, and timber bridges. The return trip is very much part of the experience, not just a way to get back.
Why it works: Perfect as a two-day combo with your reef cruise. Spend day one underwater, day two in the canopy. Some operators package both together, so you can lock it all in one go and spend less time planning and more time actually being there.
3 Days In Cairns: Reef + Skyrail + Kuranda + Daintree Rainforest
If you’ve got three days, don’t leave Cairns without doing the Daintree. It’s a UNESCO World Heritage-listed rainforest that’s older than the Amazon and it deserves its own dedicated day rather than being squeezed into an already packed itinerary.
The day starts with a hotel pickup from Cairns CBD and a scenic drive north into one of the world’s oldest living ecosystems. From there, you’re cruising the Daintree River looking for estuarine crocodiles and native birdlife, walking an elevated boardwalk through ancient rainforest with an eco-accredited guide, and if the mood strikes, cooling off with a freshwater swim before lunch at a local cafe. The afternoon takes you to Cape Tribulation Beach, one of those genuinely rare spots where the rainforest meets the reef in the same frame.
Why it works: The Daintree is ancient, remote, and completely different in feel from anything else on this list. Do the reef on day one, Skyrail and Kuranda on day two, and save the Daintree for day three. Some operators offer combo packages covering all three, so you can book them together and sort the logistics in one go.
That’s A Wrap!
Cairns has a habit of surprising people. Most visitors arrive expecting a reef trip and leave wondering why they didn’t stay longer. The outer Great Barrier Reef is world-class, period. But pair it with a helicopter flight above the coral, a gondola ride over ancient rainforest canopy and a full day in the Daintree, and you’ve built a trip that covers two UNESCO World Heritage sites, three iconic experiences and enough memories to last well beyond the flight home.
So next time someone asks what to do in Cairns, you already know the answer. Do the reef and do everything else.
