Glass bottom boat tours: Making the Great Barrier Reef accessible to everyone

Wondering if you can see the Great Barrier Reef if you can't swim? A glass-bottom boat tour is the answer. Set off from Cairns and glide over coral gardens and marine life without ever entering the water, no snorkeling ability required. With shaded seating, clear underwater views, and easy access for all ages, it's a comfortable, memorable way for families, seniors, and non-swimmers to experience one of the world's greatest natural treasures.

Live marine commentary

Knowledgeable guides explain reef biology, fish species, coral reproduction, and the ecosystem’s fragility, making the tour educational.

Camera-ready views

Glass panels provide unobstructed photo opportunities—no waterproof cases required, perfect for casual photographers or social media shots.

Combine the tour with scenic island stops

Many tours include stops at islands like Green Island or Fitzroy Island, or a full outer reef pontoon day, so you can pair the glass-bottom boat with a full day out rather than a standalone trip.

Glass bottom boat on the Great Barrier Reef: Experiencing the reef without getting wet

Check-in & boarding

Show up, check in, step onto a stable, purpose-built vessel, no wetsuit, no fitting a mask, no getting in the water if you don't want to. The crew's safety briefing covers exactly what to expect, so there's no guesswork once you're on board.

Cruise to the reef or island

Sit back as you cross the Coral Sea, with guides pointing out islands and reef formations along the way. This part's identical whether you're a confident diver or have never set foot on a boat.

Glass bottom boat reef viewing

This is the part that makes the whole trip worth it: turtles, coral, and reef fish appear right beneath your seat, no snorkel skills, no luck required, just look down. Guides narrate what you're seeing in real time, so you're not left wondering what that shape in the coral actually is.

Heading back

Relax on the return crossing, no rush, no gear to rinse off, just the reef views on the way home too.

Optional extras, entirely your choice: If anyone in your group does want to snorkel, dive, or try a semi-submersible, most tours let you add it on the day, nobody's locked into "dry boat only" if someone in the group changes their mind.

Things to know before booking a Great Barrier Reef glass-bottom boat tour

  • What it actually is: A boat with a clear underwater viewing section in the hull, so you look down at coral and marine life through glass panels while staying completely dry.
  • Glass-bottom boat vs. semi-submersible: Glass-bottom boats are open-air; you look down from your seat. Semi-submersibles are enclosed, air-conditioned cabins with side windows, more like a submarine. Both are non-swimming options; several of our tours include access to one or both.
  • What you'll typically see: Coral gardens, giant clams, reef fish, sea turtles, and reef sharks are common sightings, though what you see on the day depends on the site and conditions.
  • Where our tours go: Green Island, Fitzroy Island, and the Moore Reef pontoon are the departure points across our glass-bottom boat tours, each pairing the boat ride with a different setting, island beach time, rainforest trails, or a full outer reef pontoon day.
  • Motion sickness: The transfer out can get choppy on open water. If you're prone to seasickness, take medication before departure; this affects the boat ride itself, not the glass-bottom viewing, which is calm since the vessel is stationary or slow-moving during viewing.
  • Standalone vs. bundled: Some of our tours are built entirely around the glass-bottom boat experience; others include it as one part of a longer reef or island day. Check each tour's inclusions to see which fits what you want.
