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.

Outstanding Views of the Reef! - This was an outstanding experience! The coral reef, the fish, and all the other creatures of the reef were amazingly clear. This is a tremendous way to see the reef, even better than snorkeling. The staff were wonderful and we highly recommend this activity.

Exciting Experiences on Green Island - We did the underwater Seawalker and glass bottom boat tour. From beginning to end, everything about the tour and the experiences was very well organized from check in/collecting tickets to arriving at the island and knowing what activities/options are available at what times. We didn’t feel rushed during or in between experiences despite picking 10:30 am departure to island and 2:30 pm departure from the island. It felt like a perfect amount of time for the booked experiences and to walk around the island a bit

Seeing the great barrier reef up close - It was interesting and t he guys worked extra hard to make sure everyone felt safe. I was disappointed that we only stayed below the float. Very limited coral and small fish.
But it was an experience I'm glad I had. Would I do it again, no, but I was not able at my age, 82, to feel comfortable snorkeling anymore. So I can say I saw the great barrier reef first hand.
The glass bottom boat was great, in my opinion the high light of the tour.being at the great barrier reef

Don't bother - We booked this through Viator and, without a doubt, this was THE worst experience with Viator, ever!! When I initially booked it, I requested information about whether there would be a problem with my completing this activity, because of my medications. I received no response from the vendor, Quick Silver in Cairns Australia. Trying to find the location of the vendor was a challenge because the name Quicksilver did not appear in any of the Marquee displays, at their headquarters. Instead, it was Silver Swift. It was not until we were on the boat to Green Island that we found out that I would not be allowed to participate in the seabed walk because of a medication I am taking. If we had known this ahead of time, we would have opted for a different tour. Shame on you, Viator, for not protecting your clients. The tour itself was 20 minutes walking in circles beneath the boat. We have been purchasing Viator tours for over a decade. After much effort we received a refund for a portion of the tour.

Beware! Medications can prevent your participation - This is THE most duplicitous Viator tour ever! In March I contacted the vendor to determine if any of the medications I take would prevent me from participating. They sent me a form which I completed and returned, but heard nothing. No news is good news? Au contraire! The day of the tour we arrived at Quicksilver on Spence St (that was a complete mess -- no where did it say Quicksilver in the entire facility -- you had to intuit it was there!) Received our tickets then sat outside (on a low wall) for 45 minutes. On the boat we were given the same form I had previously filled out, only to be told that I was ineligible because of one medication. My husband was eligible, but if we had known ahead of time, we would have done something else. No transparency. The actual seabed walk was a joke. 15-20 minutes of walking in a circle under the boat. This is an absolute scam. To add insult to injury, getting Viator to provide a refund for half of the expense is excruciatingly difficult. We have used Viator for about 10 years, but that may be coming to a close soon!
