A swift catamaran from Cairns brings you to Green Island, where a unique coral cay rainforest meets shallow reef gardens. Spend the day snorkeling, ride a glass-bottom boat, and take a short eco-walk through native flora.

You step off the fast catamaran and the island greets you with salt on the air and a green wall of rainforest shading white sand. The reef pulls at the shoreline here—shallow bommies ripple in turquoise, and the glass-bottom boat slices a clear window over coral gardens. On land, the island’s trees lean toward the sea like curious spectators.

You step off the fast catamaran and the island greets you with salt on the air and a green wall of rainforest shading white sand.

On land, the island’s trees lean toward the sea like curious spectators.
Green Island is a roughly 6,000-year-old coral cay on the Great Barrier Reef and the only cay in the region with an intact rainforest. Geologically it’s a carbonate platform built on reef growth; ecologically it’s a compact collision of marine and terrestrial life. Local custodians and scientists monitor nesting turtles and seabirds here, and island facilities reflect the steady flow of day visitors from Cairns.
Expect easy, family-friendly access: a guided glass-bottom boat gives an accessible reef overview, and snorkelling from the sand puts you among parrotfish, wrasse, and hard corals. The self-guided rainforest walk threads short boardwalks and highlights native plants and birdlife. When planning, factor in the tropical climate—monsoonal rains and stinger season alter conditions—and aim for morning departures for calmer seas and clearer visibility.
Practical tips: check-in at the Reef Fleet Terminal 45 minutes before departure, bring reef-safe sunscreen and a lightweight stinger suit in summer, and pack a dry bag for cameras. If you want quieter spots, walk the western beach or time the trip for shoulder-season weekdays. Whether you float above coral or walk under rainforest shade, Green Island serves both easy relaxation and short-form marine adventure.
No — shallow reef sections enter directly from the beach, but basic swimming skills and comfort in open water are recommended; life vests are often available.
