Port Douglas Low Isles & Outer Reef
Take a sailing boat from Port Douglas to the Low Isles — a coral cay 15 kilometres offshore — then continue to the outer reef for a full day combining coral cay walking and reef snorkelling.

Port Douglas Marina
Port Douglas Marina is the departure point for the most relaxed reef experience in Queensland — the upmarket beach town is an hour north of Cairns and its reef operators offer a more intimate experience than the Cairns fleet.

Low Isles Coral Cay
The Low Isles are a coral cay and a mangrove island 15 kilometres offshore — the lighthouse-topped cay has been a scientific research station since 1928, and its fringing reef is one of the best-studied in the world.

Low Isles Lighthouse
The Low Isles Lighthouse (1878) is still operational — the sand cay around the lighthouse is barely 300 metres long and is home to nesting seabirds whose eggs have to be avoided during the landing walk.

Agincourt Ribbon Reef
The Agincourt Ribbon Reefs are the outer barrier — a series of continuous ribbon reefs that form the edge of the continental shelf, with the clearest water in the reef system and an extraordinary coral diversity.

Crystal Turquoise Water
The outer ribbon reef water has visibility up to 30 metres — the turquoise colour results from the combination of shallow white sand lagoons and the deep blue of the open Coral Sea beyond the reef edge.

Sailback to Port Douglas
Sailing back to Port Douglas in the afternoon trade winds is among Queensland's most pleasant experiences — the forested coast and the backdrop of the Daintree mountains make the return journey as beautiful as the destination.
