About this experience
Experience the beauty of Green Island, located within the Great Barrier Reef Marine Park World Heritage Area in the Coral Sea. Board a spacious catamaran to be comfortably transported to the island just 45 minutes away from Cairns. On the island, soak in the sun, relax on the white sandy beach, or opt to discover colourful reefs on a snorkelling activity, on a glass bottomed-boat, or even in a semi-submersible watercraft.

Frequently asked questions
Which ticket should I choose — glass-bottom boat or snorkelling?
Both are included in the standard ticket price as a choice on the day. If you'd prefer not to get in the water, the glass-bottom boat lets you see the reef without snorkelling. If you want a more immersive underwater view, upgrade to the semi-submarine option when booking.
Do I need to print my ticket?
No — a mobile ticket on your phone is accepted at the boarding point.
Which departure time is better — 9:00 AM or 11:00 AM?
The 9:00 AM departure gives you more time on the island and is popular with families. The 11:00 AM departure suits those who prefer a slower morning start. Both options include the same activities.
Is this suitable for non-swimmers or young children?
Yes. The glass-bottom boat and semi-submarine options mean non-swimmers can still enjoy the reef. Children under 4 travel free (a ticket must still be booked), and under-16s must be accompanied by an adult.
What happens if the weather is bad?
The itinerary is subject to change due to weather and sea conditions. In the event of significant disruption, the operator will advise you directly.
Is food available on Green Island?
Food and drinks are not included in the ticket price, but facilities are available on the island. Bring cash or a card to purchase refreshments during your stay.
