Reviews from real travellers
Public reviews of the operators who run these tours, shown as excerpts with the source on each.
"Really enjoyed our AM tour out to low isles. 40 minutes smooth journey out to the island, approximately 30 minutes of guided snorkelling. It was worth having a guide to point out really great spots and we saw 3 turtles which was the highlight for me."
"We had a multi-generational family group and WaveDancer had something to suit everyone, from the glass-bottom boat for non-swimmers through to good options for confident snorkellers. There was genuinely more than we could fit into the day."
"Amazing day on the barrier reef. The smaller boat made it a lot easier to snorkel on the reef. We stopped in 3 places to snorkel for an hour each spot."
"Fantastic scuba diving and snorkeling. Organization and Safety a 10."
"Such a wondrous family day exploring 3 reefs snorkelling, seeing marine life and stunning reef. Staff were fabulous. Pick up and drop off easy. Food lovely."
"It was a warm, sunny day in February & perfect for sailing across the water to the Great Barrier Reef while relaxing on the outside deck & taking in the beautiful scenery & blue, blue water surrounding us."
