This is our guide on the best and worst Cairns reef tours for non-swimmers, and we’re pleased to say there’s lots of great options. Why have we prepared this? We’re passionate about the reef and want everyone to maximise their experience with it. We’ve been on the boats and seen non-swimmers gazing over the side, hoping to catch a glimpse of the reef. We know there’s better options available for non-swimmers and are here to provide our advice, to make that happen for you. This is based on our extensive first-hand experience of all the Cairns reef tours and destinations. This information is applicable to non-swimmers, people not comfortable swimming in the open ocean, families with young children, older visitors and/or those seeking a multi-dimensional reef experience.

Reef and Island Day Tour. Glass bottom boat on Great Barrier Reef in the morning, Reef Island in the afternoon.
In our opinion, the best Cairns reef tours for non-swimmers, and those travelling with non-swimmers, is a day tour that splits its time between an outer reef pontoon and Great Barrier Reef island. Why? You get the best of both worlds. The outer reef pontoons provide a range of activities, including glass bottom boat and semi submersible tours, underwater observatories and helmet diving (for non-swimmers). They have platforms lowered into the sea where you can stand waist deep and be surrounded by fish. For swimming companions, fantastic snorkelling from the pontoons. Then the islands offer splashing in the shallows, walks and land-based activities. We recommend 2 amazing choices for the reef and island tours, both have daily departures from Cairns. Let’s look at them both.
Sunlover Cruises is our top pick for non-swimmers and mixed groups. This one includes 2 hours at their Moore Reef pontoon and 3 hours at Fitzroy Island.
Great Adventures is another of our top picks for non-swimmers and mixed groups. You have 2 hours at Green Island in the morning and 3 hours at their Moore Reef pontoon, which is like a floating activity center, in the afternoon.
Our Verdict: The best Cairns reef tours for non-swimmers and their companions are those that combine outer reef pontoons and islands. Something for everyone. Our Recommendation – for value and inclusions is Sunlover’s Reef & Fitzroy Island day tour. See our video trip review at the bottom of this page.
Pontoon Tours. Lots of activities for non-swimmers and swimming companions.
Cairns reef pontoon tours are another excellent choice for non-swimmers and their swimming companions. The pontoons provide a stable base at sea and offer guests a range of activities, catering to all skills and ages. These tours are shorter than the combined reef and island tours. We recommend 2 amazing choices, both have daily departures from Cairns. Let’s look at the differences.
In addition to providing reef and island day tours, Sunlover Cruises also provides dedicated pontoon tours. You have 4 hours at their Moore Reef pontoon, providing plenty of time to experience the reef and also relax on the sundecks; this is our top pick for the pontoon tours.
The Great Adventures Great Barrier Reef Adventure is another of our top picks for Cairns reef pontoon tours. You have 3 hours at their Moore Reef pontoon, providing plenty of time to experience the reef and enjoy the views.
Our Verdict: The pontoon tours provide you with more time on the Outer Great Barrier Reef. Our Recommendation – for value and inclusions is Sunlover’s Reef Pontoon tour – which gives you 4 hours at the reef, compared to Great Adventures which gives you 3 hours.
Island Day Tours. Choose between Green Island and Fitzroy Island, for a fabulous day tour.
Cairns island tours are probably the most ‘obvious’ choice for non-swimmers, because they are land-based tours, so you’ll be in your comfort zone the whole time. There are two main destinations, Green and Fitzroy Island, which offer slightly different experiences and activities for guests. Our Top Tips: Green Island’s boardwalks make it better for accessibility and prams, and its sandy beaches are great for young children. Fitzroy Island provides more land-based activities and hikes; the coral beaches can be hard underfoot. Let’s look deeper at the differences and our picks for top tours.
The Great Adventures Green Island day tour has 2 departure and 2 return times, so you can choose how long you want to spend on the island. If you pick the earliest and latest time, you’ll have up to 7 hours at Green Island. There are half-day Green Island tours available, but the price is the same, so you may as well maximise your island time.
Sunlover Cruises provides full day tours to Fitzroy Island, with up to 6.5 hours to enjoy and explore the island. Fitzroy Island has island walks to the lighthouse and summit and is home to the Cairns Turtle Rehabilitation Centre, which you can visit.
Our Verdict: The island tours are focussed on the island experience, with a reef component. The reef accessible from the island’s is not as good as the pontoons. If you are travelling with small children, Green Island will be better. For mature non-swimmers, Fitzroy Island offers a greater diversity of experience.
Reef Boat Tours. The worst choice for non-swimmers. Spend the day watching everyone else enjoy themselves.
There’s nothing worse than being stuck on a small boat for 6 hours with nothing to do but stare at the horizon, while everyone else has fun. We’ve seen people spend hundreds of dollars to sit on the boat and watch; we don’t want that to be you! These are the boats to avoid for non-swimmers.
Our Verdict: Cairns reef boat tours are not suitable for non-swimmers. Choose one of the other options and have an amazing time exploring the Great Barrier Reef.
Absolutely. By choosing a tour with a reef pontoon or a glass-bottom boat, you can see the reef without ever getting your hair wet. Pontoons feature underwater observatories and semi-submersible tours that bring the reef to you.
On a glass-bottom boat, you sit and look down through windows in the floor. On a semi-submersible, you sit below the waterline and look out through large windows on the side, giving you a view similar to what a scuba diver sees.
Yes! Options like Helmet Diving (Sunlover Cruises) or Scuba Doo (Great Adventures) allow you to walk or drive an underwater scooter along a platform. You wear a helmet that keeps your head and face completely dry, meaning you can even wear your glasses.
Green Island is generally better for accessibility and young children due to its flat boardwalks and sandy beaches. Fitzroy Island is a great choice for those who enjoy rainforest hiking and more mountainous scenery, though the beaches are mostly coral-based.
Avoid “Snorkel Express” boats or dedicated dive vessels that do not carry a glass-bottom boat or have a pontoon. On these tours, if you don’t get in the water to snorkel, you will likely be stuck sitting on the boat for several hours with nothing to do.
On most pontoon-based tours, the glass-bottom boat and semi-submersible tours are included in your ticket price and run on a schedule throughout the day. However, “extra” activities like Helmet Diving or Helicopter flights should be booked in advance as they have limited spaces.
If you’ve found this page, our guess is you’re planning a trip to the Great Barrier Reef but you (or someone in your group) can’t swim.
