What You Can Expect

Outer Great Barrier Reef Dive and Snorkel Cruise from Port Douglas

Outer Great Barrier Reef Dive and Snorkel Cruise

Explore the outer reaches of the Great Barrier Reef with this full-day adventure to Agincourt Reef, which sits at the edge of the Continental Shelf. After pickup from your Port Douglas hotel, board a comfortable 95-foot (29-meter) catamaran and settle in among the inside cabin seats or sun decks for the scenic ride out to the reef. 

Throughout the day, visit three renowned dive sites that the cruise has exclusive access to, and customize your adventure with different options for exploring the reef. If you prefer to stay close to the surface, splash into the clear waters with provided snorkeling equipment and either snorkel on your own or join a guided tour. Or, go even deeper with a scuba experience. Beginning divers can try an introductory dive, and those with scuba certification can embark on up to three certified dives. 

No matter what you choose, you’ll get an up-close perspective on the spectacular ribbon reef teaming with an array of marine life such as schools of tropical fish, small reef sharks, massive coral formations and giant clams weighing up to 440 pounds (200 kg)!

When you come to the surface, recharge with a delicious buffet lunch on board, and break for morning and afternoon tea. Grab a drink from the fully licensed bar if you’d like something stronger (own expense), and stay comfortable with facilities including restrooms and freshwater showers. After approximately 5 hours at the reef, relax and soak up views of the Coral Sea on the return trip to Port Douglas. 

Note: Book early to secure your spot, and enjoy a flexible reservations policy that allows you to change the date of your tour at no additional charge once you arrive in Port Douglas.

This was an incredible excursion! Spotless boat, incredible fun and friendly staff, smaller size, great reef stops and perfect location since we were staying in Port Douglas. The included single dive was perfect for first time divers. Great instruction.

We expected the reef trip would be great, so we booked two tours on two successive days. This, our first, included an intro scuba dive. I was initially concerned, my wife and I are around 60, and while I am very comfortable in the water I wasn't sure how she'd do. She did fine, and my children in their mid-20's also did fine. Our leader was very friendly, guided us through the intro dive well, was patient with small problems she'd treated our goggles with anti-fog and asked us to keep the masks on while on the ship, but when the ship photographer came by he asked us to remove them, and when she saw this she sighed but re-treated all of our masks, and made it a very pleasant experience. The ship was very stable and fast. Food was ample and there was plenty for vegetarians. The reef was great and we had a glorious time both days. Crew was very helpful and friendly all around.

Great experience! The staff took very good care of everyone! Would take another trip with this organization. Take care if you take any medication, I wasn't allowed to dive on the reef with scuba gear because of a medication I take. Should have been informed so I could have a doctor's slip.

I was so happy to be able to take this tour as it was the best of three trips to the Great Barrier Reef in 3 days. The seas were calm and the fish were everywhere. Although we had booked directly with Quicksilver for our tour in Cairns, we were pleasantly surprised that the operator was Quicksilver again. Thank you for making it very easy to book a tour!

Once in a lifetime experience. Excellent staff, very organized. Enjoyed the different activities available - snorkeling, underwater submarine tour, observatory, diving and even the helicopter rides. Lunch buffet was also delicious. Highly recommended!

Great tour. Staff was very dedicated to my enjoyment. The boat was great for both comfort on the ride out to the reef, and ease of getting on and off while at the reef. Simply an amazing sight to behold. Don't get to this area without seeing the reef. Surprisingly, even the lunch on the boat was very good.
