Port Douglas: Poseidon Outer Barrier Reef Dive and Snorkel

Departing from Port Douglas, Poseidon is a 24 metre catamaran offering an exciting boutique adventure, perfect for small groups of experienced divers and confident snorkellers. With access to exclusive remote reef sites, expert marine interpretation and citizen science, guest numbers are capped at 65.

The 24 meter catamaran is custom-designed for small groups of adventure-minded people. You will spend over 5 hours at the reef, visiting 3 different Agincourt ribbon reef sites, each chosen for its visual and ecological diversity.

First-time divers can enjoy up to 2 dives and take the plunge in complete confidence with an experienced dive instructor. Certified divers will enjoy up to 3 dives, all guided to maximize your experience.

Poseidon features everything you'll need to experience an underwater world of colorful marine life in safety and comfort.
Enjoy hydraulic dive and snorkel platforms for easy water access, spacious deck areas, freshwater showers, change rooms, and even a licensed bar to share tales of your adventure.

As an added bonus during the whale season, Poseidon has one of the few permits available from the Great Barrier Reef Marine Park Authority that allows guests to swim with dwarf Minke whales if encountered – a truly unforgettable experience from July through September.
