Step-by-step itinerary
Half-day Green Island reef cruise
- Start tour at Reef Fleet Terminal
- Boat ride to Green Island
- Snorkel or glass bottom boat tour
- Explore Green Island coral cay
- Return to Cairns
The experience
The boat leaves Reef Fleet Terminal in Cairns and takes you out on a modern air-conditioned catamaran: about an hour's ride to Green Island, a coral cay that sits alone in the reef. You get roughly two hours on the island itself, which is where the day splits depending on what you've chosen. If you've picked snorkel gear, you're in the water with the reef right there. If you've booked the glass bottom boat, you stay dry and watch the coral and fish move past the windows. The semi-submersible tour works the same way. You descend partway into the water but stay inside, so the reef comes to you without the wetsuit.
The catamaran handles the return trip the same way it came, and the whole thing, terminal to island to terminal, sits inside four hours. An English-speaking guide travels with the group. Food and drinks are available to buy on the island, and snorkel gear is part of most options, though you can also book transfers alone if you'd rather bring your own equipment or skip the water entirely.

Is this one for you?Book the 9am departure if you want the morning on the reef and the afternoon free. The 1pm cruise suits a later start or a full day split between other Cairns activities. The semi-submersible option lets you see the coral without entering the water: useful if you're not a confident swimmer or prefer to stay dry.
