Last minute revelation was disappointing
We booked this event for three and unfortunately my self and my wife were not allowed to participate because of our Diabetic condition. We were disappointed to know this at the last minute. I wish Viator would list Diabetes as one of the health conditions that will prevent people from participating in this adventure. My daughter was allowed to go and she had real fun. She loved the experience. I was happy the way the way our request for refund was handled. I received my refund immediately after my request. I would advise you to check with the tour operator, if you have any health condition, before booking so that you are not disappointed.
Response from the operator: Thank you for taking the time to share your feedback. We’re sorry to hear that you and your wife were unable to participate on the day, though we’re pleased your daughter still enjoyed the experience and that the refund process was handled promptly. As outlined in the listing, certain medical conditions and medications may preclude participation, and customers are advised to contact the supplier directly for clarification prior to booking if they have any concerns. Due to the wide range of medical considerations that may apply, it isn’t possible to list every condition individually on the page. We do strongly encourage guests with any pre-existing health conditions to reach out to us in advance so we can provide the most accurate guidance and help ensure the best possible experience.

I love every minute of...
I love every minute of this excursion. The whole team is very organized and detailed cares for each of us. Beautiful Green island.
Response from the operator: We loved that every minute was enjoyed with us at Green Island! Thank you for sharing!

Wonderful location
My Neice had an absolutely wonderful experience. Sadly due to pre-existing medical conditions, 2 of us were unable to participate.
Response from the operator: Thank you so much for your kind feedback. We’re thrilled to hear that your niece had such a memorable experience with us! We completely understand how disappointing it can be when pre-existing medical conditions prevent others from participating. Safety is always our top priority, especially for helmet and scuba diving experiences. We truly hope to welcome you all on board in the future, and we’d be more than happy to help explore suitable options so everyone can join in safely.

Wow isn't enough to describe this
Excellent experience. This really is an ALL DAY activity. If you don't catch the 8:30 boat to the island, you'll most likely regret it. The Seawaker experience is unique and my claustrophobic wife who freaks out at everything thoroughly loved it. Follow the instructions of the guides and everything will go fine. Safety is their utmost goal with you having an excellent experience a close second. Lycra suites and beach shoes come with the experience. After this you can snorkel (keep the suit on and grab a mask, snorkel and flippers). Again, those are part of your experience. They video and take pictures of you when you do the Seawalker experience. Ours was nicely done and, even though it's rather pricey, we opted for the USB stick of everything. Snorkeling was a gas. We're 66 and 68 respectively. They gave us life vests to help us float and we spent over an hour watching the various fish, coral, baby crocodiles about six inches long, turtles, and plants. After that we washed off, had lunch at one of their venues, then jumped in their fresh water pool and later sat on lounge chairs around the pool. They have places on the beach too to sit under an umbrella. They have a restaurant too but we chose the little burger place instead. We both finished the day at the pier in Cairns where we ate at Dundees (yeah, named after the man himself). You can get kangaroo (excellent by the way, better than fillet minion - and that's my wife talking who is squemish sbout everything she eats). You can get it as "Hop Rock" or the next thing down on the menu - "Crocodile Rock". Rock means they serve it on a piece of volcanic rock and you cook it yourself. Not for kids. Overall, this is an experience of a lifetime.
Response from the operator: Thank you so much for taking the time to share such a detailed review! We’re thrilled to hear that both of you had an excellent experience and that the Seawalker adventure was enjoyable, even for those who may feel a bit apprehensive. We really appreciate your tips for future guests and are glad the photos and videos added to the memories. We’d love to welcome you back for another adventure anytime (and it sounds like you chose a lovely restaurant to dine at later that evening in Cairns!).

Green Island Seawalker & Snorkel or Glass Bottom Boat from Cairns: questions travelers ask
Practical detail on this experience, plus the wider planning questions for Cairns & the Tropical North.
How much does Green Island Seawalker & Snorkel or Glass Bottom Boat from Cairns cost?
+
Prices start at $207 per person. The final price depends on the date, the time slot and the number of travelers, and peak weekends in Cairns & the Tropical North usually price higher than midweek mornings. Live pricing and remaining availability are confirmed on the booking screen before you pay.
How long does Green Island Seawalker & Snorkel or Glass Bottom Boat from Cairns take?
+
Plan for about 5 hours from start to finish, not counting travel to the meeting point. Most travelers leave another 30 minutes on either side so the rest of the day in Cairns & the Tropical North is not rushed.
Is Green Island Seawalker & Snorkel or Glass Bottom Boat from Cairns worth it?
+
It holds an Outty Ranking of 52 out of 100, which we label "Worth a Look". That score blends traveler sentiment (4.1/5 across 98 reviews), the depth of that review evidence, recent booking momentum, value for money against comparable last minute in Cairns & the Tropical North, and how flexible the cancellation terms are.
Can I cancel or reschedule Green Island Seawalker & Snorkel or Glass Bottom Boat from Cairns?
+
Yes. Cancel free up to 24 hours before the start time for a full refund. Inside that window the booking is non-refundable, and no-shows are not refunded.
Is Green Island Seawalker & Snorkel or Glass Bottom Boat from Cairns suitable for kids and families?
+
Yes, all ages are welcome. Families should still weigh the 5-hour running time, and strollers are easier on the earlier, quieter departures.
How far in advance should I book Green Island Seawalker & Snorkel or Glass Bottom Boat from Cairns?
+
Around 34 people booked this in the last 30 days, so popular slots go early. Two to three weeks ahead is comfortable in shoulder season, while summer weekends and holidays in Cairns & the Tropical North can sell out a month out. Same-day spots do open up when other travelers cancel, so it is worth checking if you are already in town.
What should I bring or wear?
+
Bring photo ID, your booking confirmation on your phone, a refillable water bottle and comfortable shoes. Dress for the weather in Cairns & the Tropical North and add a light layer if any part of the 5-hour experience runs outdoors or after sunset.
Where does Green Island Seawalker & Snorkel or Glass Bottom Boat from Cairns start and how do I get there?
+
The exact meeting point and directions are on your voucher once you book, and they sit in central Cairns & the Tropical North within reach of public transport. Arrive 15 minutes early: late arrivals are treated as no-shows by most operators.
What are the best things to do in Cairns & the Tropical North?
+
On Outty we rank every Cairns & the Tropical North experience on the same 0 to 100 scale, and alongside this one the highest scorers right now include Fun, Falls and Forest Day Trip from Cairns, Passions of Paradise Great Barrier Reef Cruise by Catamaran, Tully River Full-Day Rafting: Cairns, Mission Beach or Self-Drive. The city page groups everything into most popular, highest reviewed, last minute and family-friendly so you can build a day around what actually delivers.
When is the best time to visit Cairns & the Tropical North?
+
Booking patterns follow the same curve: prices and queues climb in peak weeks, while shoulder season gives you better availability on the top-ranked experiences and more room to change plans.
How many days do you need in Cairns & the Tropical North?
+
Three full days covers the headline sights without sprinting. A workable rhythm is one anchor experience each morning, such as this one, an unhurried afternoon in a single neighborhood, then a food or nightlife booking in the evening. Five days lets you add a day trip outside the city.
Do I book through Outty or through the operator?
+
Outty ranks and explains the experiences, then hands you to Viator to complete the booking with the operator directly. The price is the same as booking on Viator yourself, and Outty earns an affiliate commission on the referral, which is how the rankings stay free to read.
What is included in Green Island Seawalker & Snorkel or Glass Bottom Boat from Cairns?
+
