There is something special about heading down to the Cairns marina in the morning knowing that you’re going to spend the day on a tropical island.
The city is waking up.
Reef boats are preparing to leave.
People are checking in with towels, hats and bags for the day.
Then you board your boat, Cairns slowly disappears behind you, and you head across the Coral Sea towards Green Island.
I’ve always thought Green Island is a wonderful introduction to the Great Barrier Reef because everything feels so accessible.
You can walk through rainforest.
Step onto a tropical beach.
Snorkel in the sea.
Look for fish and turtles.
Then wander back through the trees for lunch.
And you can do all of this on an island surrounded by the Great Barrier Reef.
For visitors staying in Cairns, Green Island is one of the easiest ways to combine an island and reef experience in a single day.

What is Green Island?
One of the most interesting things about Green Island is how it was formed.
Green Island is a coral cay on the Great Barrier Reef.
Over time, sand and coral material accumulated above the water. Vegetation established itself and eventually developed into the green tropical island visitors see today.
That’s what makes Green Island different from Fitzroy Island.
Fitzroy is a mountainous continental island.
Green Island is a low-lying coral cay.
They’re both accessible from Cairns, and they’re both beautiful, but they offer distinctly different island experiences.
The journey from Cairns to Green Island
For me, the journey is part of the day.
You leave Cairns from the marina and head out across the water.
Look back as you go.
The mountains behind Cairns create a beautiful backdrop to the city, and from the sea you get a much better sense of just how dramatically the rainforest-covered ranges rise behind the coast.
Then Cairns becomes smaller.
The water surrounds you.
And eventually Green Island appears ahead.
There’s always something exciting about approaching a tropical island by boat.
Arriving on Green Island
Green Island isn’t enormous.
That’s part of its appeal.
You don’t arrive needing to work out how you’re going to travel from one side of the island to the other.
You can walk.
And I think walking is the best way to begin.
Don’t immediately rush towards the first activity on your itinerary.
Take a few minutes to look around.
Walk beneath the trees.
Find the beach.
Look at the water.
Then decide what you feel like doing first.
You’re on an island.
You don’t need to hurry.
Snorkelling at Green Island
For many visitors, snorkelling is one of the main reasons to visit Green Island from Cairns.
The island is surrounded by fringing reef, allowing visitors to enter the water from shore and explore the marine environment.
Depending on conditions, you may encounter coral, tropical fish and other marine life.
Turtles also inhabit the waters around Green Island.
Seeing one underwater is something people remember for years.
But remember that you’re visiting a natural ecosystem.
Marine life is wild.
We can tell you what lives here.
We shouldn’t promise what will swim past you at 11 o’clock tomorrow morning.
That’s part of the excitement.
What if I’ve never snorkelled before?
That’s okay.
Many people who visit the Great Barrier Reef from Cairns have never snorkelled before.
Nobody is born knowing how to use a snorkel.
Take your time.
Make sure your mask fits properly.
Listen to the safety briefing.
Use flotation assistance if you need it.
And ask for help rather than pretending you’re confident when you’re not.
The first few minutes can feel unfamiliar.
Then you relax.
You start breathing more slowly.
You put your face into the water.
And suddenly you’re looking into another world.
Can non-swimmers enjoy Green Island?
Absolutely.
This is one of Green Island’s strengths.
You don’t need to be a confident snorkeller or scuba diver to enjoy a day here.
Depending on the particular tour and services operating on the day, there may be options for seeing the reef without swimming, such as a glass-bottom boat.
That makes Green Island particularly useful for families and groups where everyone wants something slightly different.
One person can snorkel.
Another can enjoy the beach.
Someone else can explore the island or experience the reef without getting into the water.
You can still share the day together.
Walk through the rainforest
This is something I don’t want visitors to overlook.
Green Island isn’t only about the beach and reef.
Walk through the island.
The vegetation creates shade and provides a completely different atmosphere from the bright beach outside.
When you think about where you are, it’s remarkable.
You’re walking beneath tropical vegetation on a coral cay surrounded by the Great Barrier Reef.
Take your time and look around.
Sometimes the quieter parts of an island day become the moments you remember.
Spend time on the beach
You don’t need an activity every minute.
Find somewhere you like.
Sit down.
Swim if conditions are suitable.
Read.
Watch the boats.
Look out across the water.
Walk along the shoreline.
Holiday time doesn’t have to be productive.
If you’ve travelled halfway around the world to reach Tropical North Queensland, sitting on a tropical island doing very little is a perfectly good use of an afternoon.
Can you scuba dive at Green Island?
Diving opportunities may be available depending on the operator, itinerary and your experience.
If you’re already a certified diver, check what diving is available with your chosen Green Island trip.
If you’ve never dived before, introductory diving may be available through some reef experiences, subject to age, medical and other eligibility requirements.
Always check the requirements before booking rather than assuming everybody can dive.
Green Island with children
Green Island can work particularly well for families because the experience isn’t dependent on everybody wanting to do the same thing.
Some children want to snorkel all day.
Others would rather play near the beach.
And some may be much happier seeing the reef without getting into deep water.
My advice for families is simple:
Don’t overschedule the island.
Leave room for children to enjoy being somewhere different.
Keep them closely supervised around the water, follow current safety advice and make sure everybody has adequate sun protection and drinking water.
A successful family island day doesn’t need to involve completing every available activity.
Green Island or Fitzroy Island?
This is one of the most common questions for visitors planning an island trip from Cairns.
My answer is that they are different islands.
Green Island
Green Island is a coral cay.
It is relatively compact, has fringing reef, beaches and tropical vegetation, and offers several ways to experience the marine environment.
Fitzroy Island
Fitzroy Island is a larger, mountainous continental island covered in rainforest.
It has walking trails, granite landscapes, beaches and fringing reef.
So instead of asking:
“Which island is better?”
Ask:
“Which island experience suits me?”
If you want a compact coral cay and an easy combination of reef, beach and island time, Green Island may suit you beautifully.
If you want a more mountainous island with substantial rainforest walks and trails, have a look at Fitzroy Island from Cairns.
Green Island or the Outer Great Barrier Reef?
Again, these are different experiences.
If your priority is spending as much time as possible snorkelling or diving at offshore reef sites, an Outer Great Barrier Reef trip from Cairns may be the better fit.
Green Island gives you an island experience as well.
You can walk, relax on the beach and explore the island in addition to experiencing the reef.
If you have enough time in Cairns, you don’t necessarily need to choose.
An island day and an Outer Reef day can show you two very different sides of the Great Barrier Reef.
Read our Great Barrier Reef from Cairns guide if you’re deciding between the different reef experiences.
What should I take to Green Island?
For a comfortable island day, I recommend bringing:
-
- Swimmers
- Towel
- Hat
- Sunglasses
- Sun-protective clothing
- Sunscreen
- Drinking water
- Comfortable footwear
- Dry clothes
- Camera or phone
- Any personal medication
Check your particular tour before packing because inclusions differ between Green Island packages.
Be careful with the tropical sun
This deserves its own mention.
You can burn quickly in Tropical North Queensland.
And when you’re swimming or snorkelling, it’s surprisingly easy not to realise how much sun you’re getting.
Use appropriate sun protection.
Wear protective clothing where practical.
Take breaks in the shade.
And keep drinking water throughout the day.
Don’t let sunburn become the souvenir you take home from Green Island.
Swimming safely at Green Island
Green Island sits within a natural tropical marine environment.
Conditions can change and marine hazards can occur.
Always follow the current signs and safety advice provided by your tour operator and on the island.
Marine stingers can occur in Tropical North Queensland waters, particularly during warmer periods.
If protective suits or other safety measures are recommended, use them.
And if you’re not confident in the water, tell somebody.
There’s no prize for pretending to be a stronger swimmer than you are.
Can you stay overnight on Green Island?
Yes.
Staying overnight creates a very different island experience from visiting on a day trip.
Eventually, the day visitors return to Cairns.
The island becomes quieter.
And you don’t have to watch the clock for your return boat.
If you’re interested in staying, check current Green Island accommodation availability and pricing rather than relying on old prices quoted in an article.
Accommodation changes.
Your travel dates matter.
When is the best time to visit Green Island?
Green Island can be visited throughout the year, subject to weather and marine conditions and scheduled services.
Different seasons create different conditions on the Great Barrier Reef.
Rather than waiting for somebody to nominate one perfect month, check the weather and conditions around your actual travel dates.
I’ve learned over the years that the ocean doesn’t read our marketing brochures.
Some days are beautifully calm.
Other days remind you that you’re travelling across the Coral Sea.
That’s nature.
Is Green Island worth visiting from Cairns?
If you’d like an accessible Great Barrier Reef island experience from Cairns, Green Island is certainly worth considering.
It’s particularly appealing if you want several experiences in one day without constantly travelling between them.
Beach.
Reef.
Snorkelling.
Rainforest.
Marine life.
And time simply to relax.
All on one small island.

My advice for your Green Island day
Don’t spend the whole day checking the time.
When you arrive, walk around.
Look at the water.
Go snorkelling if that’s what you’ve come to do.
Walk beneath the trees.
Sit on the beach.
Look for marine life.
Take photographs.
But also put the camera away occasionally.
One of the great privileges of visiting Cairns is how easily we can leave the city and experience places like this.
In the morning, you’re standing at Cairns marina.
Not long afterwards, you’re barefoot on a coral cay surrounded by the Great Barrier Reef.
That’s worth stopping to appreciate.
