About this tour
This eight-hour excursion ferries you from Cairns to Green Island, a genuine coral cay on the Great Barrier Reef. Spend four to five hours exploring the island and reef system via your choice of glass-bottom boat viewing, snorkelling, or semi-submersible submarine tours. The catamaran departs and returns to Northern Beaches accommodation, with morning refreshments and lunch included depending on your package selection.
Highlights
- Glass-bottom boat tours of living coral without getting wet
- Self-guided snorkelling with provided equipment all day
- Semi-submersible submarine descent to observe reef life
- Return air-conditioned catamaran transport from your hotel
- Buffet lunch and morning tea included
- Access to actual coral cay island, not just boat-based viewing
What to expect
You'll be picked up from your Northern Beaches accommodation and transferred by modern catamaran to Green Island, a forty-minute crossing. Once there, the island itself is modest but functional—you've got a few hours to choose your reef exploration method. The glass-bottom boat keeps you dry while you watch coral colonies pass below; snorkelling puts you directly among fish and reef systems if you're comfortable in the water. The semi-submersible descends deeper without requiring diving certification. Lunch is served on the island. The return journey follows the same route back to your hotel.
