Had an awesome day. The boat trip was beautiful the weather perfect and Fitzroy Island was fantastic. We snorkeled and relaxed under a shady tree looking and the beautiful water. The hot pasta and meatball lunch was ok although a little dry needed more sauce. It came with an apple and a nut and chocolate bar and water in a cute souvenir bottle. It was fun, I had an excellent day

The staff were great people and very helpful. I liked that the cost was an all included experience. My 7 year old son had the most fantastic time, just loves the reef, however he had concerns about the boat on the way out and the slapping of the water on the boat. He has been investigating boat disasters and thought we had been hit by a torpedo. 😂

Frequently asked questions about Great Barrier Reef cruises

What are my Great Barrier Reef cruise options?

Great Barrier Reef cruises are available as either half-day or full-day tours with at least 1 reef exploration activity included. You can add an additional underwater activity, an Australian lunch or some premium options like small group tours, helicopter tours or marine biologist for additional prices.

How do I get to the Great Barrier Reef from Cairns, and how long is the boat ride?

Most tours depart from Cairns' Marlin Marina. If you're heading to islands like Green Island or Fitzroy Island, travel time is typically 45 to 60 minutes by fast catamaran. Outer reef experiences to sites like Moore or Norman Reef usually take 70 to 90 minutes. Some premium packages offer helicopter transfers that take about 25 minutes. Departure is straightforward: book your preferred tour and meet at the marina for an easy launch to the reef.

How far is the Great Barrier Reef from Port Douglas?

Port Douglas, located approximately 67 kilometers (42 miles) and an hour's drive north of Cairns (or 70-90 minutes by shuttle), serves as an excellent base for reef excursions; the outer reef is about 30 nautical miles offshore, a 60-90 minute boat trip, while the closer Low Isles are just a 30-minute cruise away.

What activities can you do at the Great Barrier Reef?

Popular activities include snorkeling, introductory and certified scuba diving, scenic helicopter flights, glass-bottom boat tours, and semi-submersible rides. Visitors can also enjoy guided marine biologist tours, touch tanks, island rainforest walks, turtle rehabilitation centres, underwater observatories, and kids' waterslides or splash zones on pontoons. Some tours offer private sand cay picnics, sunset cruises, or marine education programs.

What Great Barrier Reef cruise can I take if I’m on a budget?

Half-day cruises usually begin from AU$95 while some full-day cruises with one reef activity are available for AU$105.

Book a Great Barrier Reef full day cruise

How long does it take to reach the reef?

Most cruises take 1–2 hours from Cairns or Port Douglas to reach the outer reefs.

Can I go on a cruise if I don’t swim?

Yes! Glass-bottom boat tours and underwater observatories are perfect for non-swimmers. Both activities come with select pontoon tours.

Book a Reef Magic pontoon tour

Are pontoon tours better than boat cruises?

Pontoon tours offer more time at the reef with additional amenities like waterslides and semi-submersibles. Boat cruises provide mobility between multiple reef sites.

Do I need prior diving experience?

No! Introductory dives are available for beginners under the guidance of a professional. These dives are available with pontoon experiences.

Book a Sunlover Great Barrier Reef tour

Can I eat before snorkeling or diving?

It is not recommended that you snorkel or scuba dive with an empty stomach as you may feel drained quite easily. However, opt for a light meal of fresh fruits, sandwiches or salads that can be easily digested. Avoid heavy greasy food to avoid feeling nauseous.

What is the age limit for snorkeling and scuba diving?

Typically, snorkeling is available for all ages, while diving may have a minimum age requirement, often 12 or older.

Are there weight restrictions for activities?

Helicopter rides usually have a maximum weight of 130kg. Anyone above this weight may need to pay additional surcharges to take the flight or may not be able to participate. Scuba diving has no weight restrictions as such but you may need to be physically fit to handle the activity’s demands.

Are there medical restrictions for diving?

Yes, medical restrictions apply. Guests with conditions such as asthma, epilepsy, or heart conditions may be restricted. A medical check may be needed for guests over a certain weight. We suggest that you get your physician’s approval to remain on the safe side.

How accessible are underwater activities?

Snorkeling can be accessible to all, and some cruises offer tailored support for guests with mobility needs. Scuba diving accessibility may vary and you may need to check with your provider.

How deep will I go while scuba diving?

Introductory dives usually reach around 12 meters (40 feet), while certified divers can explore deeper sites.

Which tours are best if I get seasick?

Pontoon tours offer the best solution, as they're accessed via large, stable catamarans and moor at steady platforms. Additionally, flights allow visitors to skip the boat altogether. Taking motion-sickness medication like Kwells about 30 minutes before boarding is highly recommended as a precaution.

Are reef tours accessible for people with disabilities?

Green Island is the most wheelchair-friendly destination with paved walkways and accessible marine centres. Some pontoons, like the Agincourt Reef platform, offer water-powered lifts for guests up to 90kg. Always advise the operator in advance of accessibility support and to confirm availability on specific vessels.
