Itinerary
Poseidon Outer Reef Cruises
Cruising from Port Douglas aboard the modern high speed dive and snorkel catamaran Poseidon, you’ll have more time to spend at three fabulous snorkeling and diving sites on Agincourt Reef’s outer limits. Renowned for its coral and marine life, the reef is known for being the best diving and snorkeling day trip destination from Port Douglas.
This cruise suits experienced divers and beginners alike, whether you’re a certified diver or you just want to go snorkeling. If you’re a diver, you can take up to three dives into the Great Barrier Reef’s coral gardens. You have your choice of diving from the mooring site, doing a drift drive back to the vessel or taking an excursion to less easily accessed sites depending on the conditions of the day.
8 hours
Great Barrier Reef
If you’d prefer to stay on top of the water, go snorkeling in sheltered lagoons with breathtaking drop-offs. Learn about the Great Barrier Reef’s fragile ecosystem during a reef interpretation talk, and then take a guided snorkel tour for an informed look at the reef’s tropical fish and coral.
Poseidon has been specially designed to enhance your snorkeling and diving adventure with a lowering transom for easier access to the water, an air-conditioned saloon and open deck areas for relaxing on the reef. You’ll also have plenty of chances to hydrate and re-fuel with an included morning tea, afternoon tea and buffet lunch with prawns.

Epic experience from start to finish!
Lauren was lovely when we checked in; my discount code was applied so she added a refund without fuss.
Captain Jayson set the tone from before we boarded with a lovely persona!
Photographer Queenie was a delight even helping me with advice for a future trip to the Maldives!
Eliza was such a lovely f&b host; food was incredible and so generous!
Gordon is the star of the show; authentically himself and so real! Loved his passion for the reef.
Kevin was so kind and helpful; did a lovely guided tour as well.
It’s so hard to put into words how special the day was…
The reef and marine life speaks for itself - what sets this company apart is its people and access to 30+ sites (others only go to 1 or 2 sites). We loved we could explore 3 different sites in 1 day!
We also had an educational talk from a marine biologist about coral bleaching which was fascinating!
Excellent dives on great barrier reef!
