Poseidon-dive/snorkel - 6 of us went on the Poseidon for dives and snorkeling. 5 of us are certified divers. We had a wonderful time. Gordon (our dive master) and crew were amazing! We did 3 spectacular dives and had a delicious lunch! Great Barrier Reef did not disappoint!

Snorkel tour to remember - We took a cruise on Poseidon from Port Douglas about a week ago and it was a once in a lifetime experience getting to snorkel at the Great Barrier Reef. Our van driver Uta was wonderful and once on board, there was a Marine Biologist named Fern that really went above and beyond for my husband. He has a fear of the water and this was very out of comfort zone. Fern pulled him around with a floatation device until he gained enough confident to snorkel solo. She made the day great for us and we couldn't have been happier. We appreciate you, Fern!

Must do in Australia! - Great one day dive trip to Outer Great Barrier Reef! I felt very comfortable with our dive leaders and the equipment was very good. Visibility was somewhat limited due to a recent cyclone in the area but the coral life was bountiful and very impressive. Poseidon had many staff on board including a marine biologist to help and explain the reef. Food on board left a little to be desired but who goes on a dive trip for lunch? Poseidon Dive Trip from Port Douglas checks a box on the Bucket list!

Fantastic day out! - We went on the boat today and completed two incredible dives with Gorden, and a snorkel with Glen. Both were very knowledgeable and informative and we learnt so much about the reef and the animals. Gorden showed us a nursery of white tip reef sharks which was fantastic, alongside lion fish, sting rays, parrot fish, and all the different types of coral that Glen covered in his talk. We’d like to thank every member of the crew for being so friendly, kind, funny and putting our safety first whilst making sure everyone had a good time! We couldn’t have asked for a better day. The food was also 10/10.

Diving with Gordon - We did two dives with Gordon. He was an absolutely amazing dive master. We went to Phill's bommie, what a perfect dive site. Gordon showed us lion fish and took us to the coolest shark nursery where we saw more than 9 white tipped juveniles. Couldn't recommend this trip enough. The whole crew were so helpful and Glen the marine biologist was so informative and interesting. Karen

Reef speaks for itself; what sets them apart is their people with their passion and personality! - 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!
