About this tour
A 4.5-hour reef expedition departing from Cape Tribulation that takes you to two separate snorkel sites—Mackay and Undine Reefs—where you'll spend roughly two hours underwater exploring coral gardens and swimming amongst sea turtles. The boat carries maximum 25 people, keeping crowds manageable. You'll encounter tropical fish, eagle rays, giant clams and starfish across pristine sections of the Great Barrier Reef, with onboard naturalists explaining the ecosystem as you go.

What to expect
You'll board from Cape Tribulation and motor out to the first reef site. Expect a briefing on marine life and safety before entering the water. The reefs themselves are busy with colour—clownfish, parrotfish, wrasse and larger pelagics moving through the coral. Turtle encounters are common but unhurried; you'll observe them grazing and moving through the reef structure. The second site offers a different reef character. Between sites there's time to dry off, drink water and listen to naturalists discuss what you've seen. The pace is relaxed, not a race through checklist spots.
