Are Cairns boat tours worth it? What 16,264 reviews actually say

Three figures matter when you are deciding whether a day on the water out of Cairns is worth the money, and all three are on this page.

The sample size. 16,264 reviews across eighteen listings. It is also concentrated: $193 has 3,875, $126 has 1,931, $79 has 1,916, $193 has 1,654 and $203 has 1,626. Those five listings alone account for more than ten thousand ratings, which is a lot of people describing the same stretch of water.

The average. 4.7 across the eighteen. That is the figure people ask for and it matters less than the spread around it, which is tight. The lowest score here is 4.1, on $77, the four-hour morning at Green Island that is also the lowest fare among the reef and island days. The highest is 4.9, on $147 from 626 reviews. Six listings sit at 4.8 or above. There is no bad end of this market to fall into by accident.

The price band. Fares run from $54 to $470, but the full range flatters itself at both ends: the bottom is a ninety-minute evening on the inlet and the top is two days with a bed on a yacht. The band where the choosing actually happens is $77 to $216, and inside it you are mostly buying hours, moorings and meals rather than a better reef.

What the numbers cannot tell you. What the water looks like on your date, or what passes underneath you. No listing on this site promises conditions and a 4.7 average is not a forecast. What it does tell you is that a very large number of people rated these days highly across every kind of weather a year contains, which is itself part of the answer.

The cheapest morning is the one people rate lowest. $77 is four hours to Green Island and, at 4.1 from 468 reviews, the lowest score here. It is a half-day crossing to an island and it does what it says. If you want the day to be the memory rather than the errand, $79 is the five-hour version at 4.4 with the glass-bottom boat and the island’s pool and rainforest walk, and $203 is the same island under sail with 25 guests on board at 4.8.

Nine hours is a lot of hours. If a full day is more than you want, the half days here are complete products rather than compromises: $126 at four hours with 1,931 reviews at 4.7, and $147 at five hours with 626 reviews at 4.9. Both go to the reef; both have you back with an afternoon in hand.

A big boat is not everybody’s day. The most-reviewed listings here are the large vessels. If a crowd is the part you would rather avoid, $182 is seven hours in a small group at 4.8, $203 carries 25 guests on a 16-metre sailing boat, and $182 starts at Deeral and cruises rainforest waterways before the coral reefs at the outer edge, 4.8 from 147 reviews.

The two-day trips are a different purchase. $298 and $470 are not long versions of a day out; they are itineraries with a night in them, and the second one puts that night on a yacht with a night dive. If that is what you came for, the fare is the fare. If it is not, the single-day listings between $77 and $216 carry thousands of reviews between them.

One evening, arriving late. $54 is ninety minutes on the water at sunset with a drink, 243 reviews at 4.6, and the lowest fare here. $102 is two and a half hours along Trinity Inlet with dinner on a catamaran, 423 reviews at 4.5.

One full day, and you want the most-booked option. $193. Nine hours at the outer reef with a meal, snorkel or scuba, 3,875 reviews at 4.8 — by a wide margin the largest body of feedback on this site.

One full day, and you want the most water for it. $216, our pick: the Silverswift catamaran to three different reef sites in eight hours, snorkel or dive at each, 657 reviews at 4.7. Three sites instead of one is the argument.

Half a day. $126 for four hours with a guided snorkel and a choice of moorings, or $147 for five hours with marine biologist guides and fifteen exclusive moorings, the best-rated listing here at 4.9.

You would rather stay dry. $200 for the multi-level pontoon with its glass-bottom boat and waterslide, or $79 for Green Island with the same choice. Anyone hunting the best glass bottom boat tour Cairns has on offer is choosing between those two, and the numbers are 403 reviews at 4.5 and 1,916 at 4.4.

An island rather than open water. $200 pairs the Moore Reef pontoon with Fitzroy Island and a buffet lunch; $182 takes the rainforest waterways from Deeral out to the reef; $203 does Green Island and an exclusive reef site under sail.

Two days. $298 for one day at the reef and one in the Daintree with meals included, or $470 for two days of diving and sailing with a night aboard the yacht.
