The 15 Best Great Barrier Reef Snorkeling Trips

33 tours  ·  from $45 a head

Inner reef is closer and cheaper, outer reef is better and a longer ride. These 15 sort the day boats out of Cairns and Airlie by which reef they actually reach, what the platform is like and how much of the day is sailing.

Review of Wavelength’s Port Douglas Outer Reef cruise, with three snorkel sites, marine biologists, meals, photos, and practical booking advice.

“With Marine Biologists on board, and leading snorkeling tours what's not to like. The team are also helping regrow the coral and take readings for the national centre. Plenty of drinks and cake, possibly too much cake... Lol that's probably the only area to pick up.”

Review of Puerto Morelos reef snorkeling: small groups, two 45-minute swims, gear included, family tips, price, logistics, and drawbacks.

“Everyone involved with our snorkeling trip to the reef was fantastic and helpful. We were fitted for gear and checked in, and accommodations were made for a diverse group of inexperienced snorkelers. We had a great skipper and our dive master kept us from harming the fragile reef all while letting us get a glimpse of the local aquatic life. My wife was a wee sick and woozy from the boat ride, and all of the staff were kind and considerate in helping her get her land legs back.”

Review of Cairns’ fast Outer Great Barrier Reef snorkel tour, with marine biologists, 15 reef sites, gear, snacks, and practical tips.

“This was a truly memorable experience and allowed us to tick off a once in a lifetime bucket list activity. The day started with a very informative presentation by Kiki on the different living species that we could look forward to seeing on our adventure. What was really pleasing to note was the various preservation projects that the company was associated with to help sustain this unique environment. After the presentation we were kitted out with our snorkel, mask, flippers and stinger suit. All items were of great quality and reflected the professionalism of this company. The boat was new and purpose built for visiting one of their 15 exclusive…”
