Outer Reef and Coral Cay Snorkel and Dive Cruise from Cairns

4.8 (1,626 verified reviews)

About This Experience

Ocean Free and Ocean Freedom run this day on a fast 20-metre catamaran, and 1,626 reviews give it a 4.8 rating. You check in at the Reef Fleet Terminal on Spence Street and walk about three minutes to the boat at Marlin Marina. Hotel pickup is only available as an extra you book directly with the operator at least 48 hours ahead.

Breakfast on board is a Danish pastry, fresh fruit, tea and coffee during the 75-minute run out. Both sites are on Upolu Reef, inside Marine National Park Green zones. The first is the Wonder Wall on the reef's outer edge, where the coral comes to within a metre of the surface and you snorkel along the top of the wall. The itinerary gives about two and a half hours here, with a glass-bottom boat ride (sea conditions permitting) and a guided drift snorkel led by a marine biologist or interpreter.

Lunch is an hour-long spread of prawns, smoked salmon, cold meats, a chicken platter, three salads and bread. The afternoon brings another two and a half hours at the Upolu coral cay, a sandbank where turtles, blue-spotted stingrays and damselfish are often seen. On some low-tide days you can stand on the cay itself; when the tide or swell won't allow it, you snorkel the shallow water around it. The day finishes with a fish feeding and a 75-minute ride home with fruit, cheese and cake platters, reaching Cairns around 4:30pm.

This suits people who want as much time in the water as possible and like to learn what they are looking at. Introductory and certified dives are extras, up to two per person, and first-time divers go two to one instructor on their first dive. Every diver completes a medical form on the day, so tell the operator about any conditions or medication beforehand.

Bring swimwear, a towel, sunscreen and sunglasses. Snorkel gear with prescription masks, Lycra or wetsuits and flotation devices are supplied, as are chilled water and fresh-water showers. Soft drinks and alcohol are extra. You need to move around a moving boat and step down into the glass-bottom boat, and reviewers who get seasick recommend taking tablets before departure.

What Travelers Say

Rated 4.8/5 by 1,626 verified GetYourGuide travelers.

The booking process thru Book your guide is flawless. The tour meeting point is at the Fleet terminal. The crew is exceptional. The glass bottom boat ride is the first activity followed by snorkeling and scuba pre and post lunch. The crew is exceptional ésp John. Very patient and considerate. We really did not have the food due to sea sickness and bad weather. Would unhestatingly recommend this operator

We loved our trip to the outer reef to snorkel and scuba dive. The boat was great, the staff was great, the reef was beautiful. The staff was really helpful and kind. They explained everything really well and helped everyone onboard to have a great experience.

Awesome, I snorkelled twice and bought 1 introductory dive and it was magical. The staff were incredible, patient and went through all the safety features and instructions. Mia was excellent and took me out 1:1 and it was magical, we were out for 20 minutes and we saw so many fish, coral and it was so exciting. As soon as I got back I booked for a second dive. We went to 2 different dive sites on the reef Upolu Cay and Wonder Wall, both fantastic. The food was plentiful and really good with a variety. I can’t praise the crew and captain enough, they were awesome and so knowledgeable about the reef, fish and enthusiastic about your experience and loving the diving experience. Highly recommended to take the Ocean Freedom tour, it was amazing

Frequently Asked Questions

Can you really stand on the sand cay?

On some low-tide days, yes. When the tide or swell doesn't allow a landing, you snorkel the shallow water around Upolu Cay. If a guaranteed beach landing matters, the <a href='/tours/michaelmas-cay-and-great-barrier-reef-full-day-snorkel/'>Michaelmas Cay day</a> ferries guests to the beach.

How much time do you get in the water?

The itinerary gives about two and a half hours at each of the two sites, with an hour for lunch between them.

How does scuba diving work on this boat?

Dives are extras. Certified divers can do up to two guided dives, and first-timers can do up to two introductory dives, going two to one instructor on the first. Everyone completes a medical form on the day.

Is hotel pickup available?

Only as an extra booked directly with the operator at least 48 hours before your trip. Otherwise you check in at the Reef Fleet Terminal and walk to Marlin Marina.
