Spend a relaxed six hours on two contrasting Great Barrier Reef sites—Wonder Wall and Upolu Cay—aboard a luxury catamaran from Cairns. Expect guided drift snorkels, a glass-bottom-boat tour, wetsuits, and a seafood smorgasbord in Marine Park protected waters.
More ways to explore the area's outdoor wonders
You step from the Reef Fleet Terminal onto a sleek catamaran and the ocean takes the pace—its blue reaches daring you forward as the city shrinks behind. Within an hour the hull settles and the first stop appears: Wonder Wall on the outer edge of Upolu Reef, a dramatic drop-off where fish swirl like punctuation marks against sculpted coral.

The Great Barrier Reef is a UNESCO World Heritage Site and lies offshore from traditional owner lands such as the Gimuy Walubara Yidinji and neighbouring groups, who maintain cultural ties to these waters.
Conservation
Sites visited are in highly protected Marine Park zones where no fishing is allowed; practice reef-friendly behaviors—no touching coral, use reef-safe sunscreen, and follow crew guidance to minimize impact.

Book early and check-in times
Arrive at the Reef Fleet Terminal counter at 7:15am and complete pre-boarding waivers to avoid delays; boarding usually starts at 7:30am.
Use reef-safe sunscreen
Apply biodegradable sunscreen before boarding and reapply as directed to protect coral and avoid fines in some zones.
Manage seasickness proactively
Take motion-sickness medication 20–30 minutes before departure if you’re prone to nausea; the catamaran is stable but open to swell.
Follow marine guide briefings
Stay with the guided drift snorkel groups and use provided buoyancy vests if needed—guides know the safest lines and best viewing spots.
Reef-safe sunscreen
Protects your skin and the coral—apply before boarding and reapply between swims.
