AquaQuest Port Douglas Great Barrier Reef Day Trip


Experience a luxury day trip to snorkel and dive the Great Barrier Reef from the beautiful tropical town of Port Douglas. Join us for a once in a lifetime adventure to the outer reef, one of the world’s natural wonders.

Whether you’re a snorkeller, a first time scuba diver or a certified diver, our friendly and passionate crew will craft your perfect day! We’ve been operating Great Barrier Reef cruises for over 40 years, and as an Advanced Eco Certified Operator, we’re passionate about sharing our expert knowledge of the beautiful sites we visit.

AquaQuest is our latest vessel, featuring state of the art equipment and facilities for unrivalled comfort, such as easy access platforms for snorkelling and introductory diving, spacious seating and sun loungers.

During your Great Barrier Reef day trip we’ll visit two reef sites, selected from our nine exclusive moorings at Agincourt, St Crispin’s and Opal reefs. These pristine outer reef sites have an amazing variety of colourful wildlife – whether you’re snorkelling or diving, you’ll be enthralled by tropical and pelagic fish, rays, turtles, wrasse, sharks and more!

Your day includes a delicious hot and cold tropical buffet lunch that will satisfy your appetite in between snorkel and dive sessions.

“After some research into the numerous dive companies operating out of Port Douglas, we were confident in booking with Divers Den on their custom built dream boat, AquaQuest. The trip was everything we could have hoped for and more… We were able to see some of the beautiful creatures that call the reef home, including parrot fish, stingrays, cuttlefish, reef sharks, jellyfish, nudibranchs and even a chilled out green sea turtle. The boat was set up perfectly, the gear was all well maintained, and staff were always happy to help. Special thanks to Lindsey, who helped my partner through two amazing introductory dives and to Roman, for his passion for the reef and expertise he happily shared.”

“We were picked up at our hotel and the driver was early, waiting for us. The boat is beautiful and the equipment for scuba and snorkelling were top notch. The dive crew was very competent and attentive, pointing out many different fish including two small sharks. My wife loved the snorkelling. Overall I had a great time on the Great Barrier Reef.”

– Ray

Medical and Altitude Info

All introductory scuba participants must meet medical questionnaire requirements and some conditions or medications may prevent you from diving.

Currently the rules state that for a single no decompression dive, you should not fly/go to altitude for at least 12 hours, or 18 hours after multiple dives. Divers Den recommends waiting a minimum 24 hours whenever possible. These are guidelines only, there is no guarantee that these recommendations will prevent decompression sickness. There are no current guidelines regarding diving after flying.

Altitude is defined as 300m/1000ft above sea level. This includes going to the Atherton Tablelands (a popular local scenic attraction), so be careful if booking tours to follow your dive trip. Under normal circumstances, you should be out of the water on your last dive at 12pm (midday).
