Poseidon Outer Reef Cruises


Departures ex Port Douglas

Poseidon departs daily, visiting 3 spectacular sites on the Agincourt Ribbon Reefs. Agincourt Reef is about 70km North East of Port Douglas and on the outer edge of the Great Barrier Reef. The crystal clear waters, beautiful corals and incredible fish life enables Poseidon to offer the very best in boat diving and snorkeling.

Poseidon caters to snorkellers, introductory & certified divers. Divers can enjoy up to 3 guided dives using large tanks & computers for extended bottom time. Dives can be drift dives, wall dives, and isolated pinnacles surrounded by pelargic fish and coral gardens.

Snorkellers can enjoy unrestricted exploration of shallow lagoons and spectacular drop-offs, teeming with an unbelievable variety of fragile corals & colourful fish.

There is also a Reef Interpretation Talk giving information on the history and ecology of the reef system, followed by a guided snorkel tour.
