“Not listed” means the listing does not state it.

Outer vs inner reef: the outer reef sites (Moore, Milln, Flynn, Agincourt, Opal) sit further offshore. The cays (Michaelmas Cay, Low Isles) are sand islands with a lagoon you can snorkel straight off. Pontoons are floating platforms moored on the reef, with facilities and a semi-submarine for people who would rather stay dry. More on the difference in Cairns reef: snorkel, dive or liveaboard.

Snorkel or intro dive?

Every trip here includes snorkelling. An introductory dive needs no licence: you dive with an instructor on the day. On the boats that list it (Evolution, the Dreamtime boat, the outer reef pontoon, Ocean Spirit and the Port Douglas outer reef cruise) it is an add-on. Silverswift lists dives for certified divers. If you want to get certified, the Curso PADI Open Water de 5 días con liveaboard es desde A$1.199; overnight trips are on the diving and liveaboards page, and the course is explained in learn to dive on the Great Barrier Reef.

How we ranked them

We sell every trip on this page, and we ranked them on four things:

1. Live price from our listings, plus extras collected on the day (fuel surcharges, transfers, dives).
2. The reef itself: outer reef or cay, how many sites, and how long you spend in the water where the listing states it.
3. What is included: lunch, guided snorkel, stinger or lycra suits, lifeguards, transfers.
4. Who it suits: strong swimmers, nervous snorkellers, first-time divers and people short on time.

We do not quote operator ratings on this page because the figures we hold for these operators do not all match the ratings shown on their tour pages.

Preguntas frecuentes

What is the best Great Barrier Reef day trip from Cairns?

For most people, a full day on the outer reef. The Full Day Outer Great Barrier Reef Tour from A$269 sails to two outer reef sites with a free guided snorkel tour; Evolution from A$269 gives five hours at two outer sites with optional dives.

Is a pontoon or a reef boat better?

A boat that moves between sites suits confident snorkellers: you see two or three different reefs. A pontoon suits non-swimmers and mixed groups: lifeguards, a semi-submarine and an underwater observatory let you see the coral without swimming far.

Can I scuba dive on a Great Barrier Reef day trip without a licence?

Yes, as an introductory dive with an instructor. Evolution, the Dreamtime boat, the outer reef pontoon, Ocean Spirit and the Port Douglas outer reef cruise list intro dives as an add-on. Silverswift lists dives for certified divers.

How long does it take to get to the outer reef from Cairns?

The outer reef pontoon day lists about 90 minutes each way on a fast catamaran. The full-day trips from Cairns on this page run about 7 to 9.5 hours in total.

Is Cairns or Port Douglas better for a reef day trip?

Both reach the outer reef. More of the reef boats we sell leave from Cairns. Port Douglas boats go to the Agincourt and Opal ribbon reefs, and Port Douglas has the Low Isles half day.

Are there hidden costs on reef day trips?

Some trips add a A$10 fuel surcharge per adult (Silverswift, Sunlover’s Moore Reef pontoon, Silversonic and the Agincourt pontoon day), and hotel transfers, dives and photos are extra on several. Each extra is listed on the tour page and above.
