Port Douglas Dive & Snorkelling Tour

Visit Three Snorkelling And Scuba Diving Locations in One Day

This popular Port Douglas dive and snorkelling tour offers visitors the ultimate reef trip adventure by taking guests to the best of the best outer Barrier Reef locations in Queensland Australia to maximise your chances to see the best corals and marine and maybe by a rare event swim with Dwarf Minke Whales.

This is not a dedicated swim with whales Great Barrier Reef tour, it is a dedicated diving and snorkelling tour that visits 3 reef sites in one day.

The Skipper has the luxury of choosing the days three reef locations you will visit based on the weather, winds, tides & currents from within the Agincourt Ribbon Reef system to ensure you snorkel and scuba dive some of the world’s best coral and reef systems that are oozing with a multitude of marine life.

We have permits for 30 reef locations permits to choose from.

This really is a highly recommended Port Douglas dive & snorkel tour that explores the northern section of the Great Barrier Reef.

The Agincourt Ribbon Reefs are long narrow reefs located along the very Outer Edge of the Great Barrier Reef, which is flushed out at every tide by clear oceanic water; coral thrives in this clear water, creating spectacular gardens and a huge variety of marine life.

All of the dive and snorkel sites have been selected for both the shallow coral gardens favored by snorkellers and adjacent deeper walls and drop-offs preferred by scuba divers.

Once aboard the reef boat tea and coffee are served and the snorkelling & diving briefings are done during the trip to the reef to maximise your time in the water.

After a high speed trip we arrived at the first site at approximately 10.00am.

Snorkelling Tours On The Great Barrier Reef from Port Douglas

The best way of seeing and experiencing the magic of the Port Douglas and Cairns Great Barrier Reef is by snorkelling and the majority of visitors choose to snorkel. Our boats crew pride themselves on offering excellent customer service, with a team of dedicated snorkelling instructors to assist your every need.

They also provide in water assistance and floatation devices like pool noodles and floatation vests for those who are beginner snorkellers or a bit frail. A reef interpretation talk is given by a marine naturalist at the second dive and snorkel site explaining the ecology and history of Australia's Great Barrier Reef.

By this time you are generally starving and its here where they serve a tropical buffet of prawns, cold meats, breads and salads (the best potato salad I have ever had.) A guided snorkel tour is offered at the third scuba diving and snorkel site by a marine naturalist and is one activity that should not be missed.

There is one guy that does it called Mr. Fluffy and I'm sure that he has gills and webbed hands and feet. This amphibious man is so knowledgeable on the reef and everyone that comes back from this guided snorkel trip just raves about him.

Scuba Diving On The Port Douglas Great Barrier Reef

For those with scuba diving certification you can enjoy up to 3 guided scuba dives at different outer reef locations. Some of the spectacular scuba diving sites include walls, pinnacles and coral gardens with a fantastic variety of fish and coral life all at the very edge of the Agincourt Ribbon Reefs on Australia's Great Barrier Reef.  All dives are guided at no extra cost and you will be briefed by your dive master on the sites, equipment and safety procedures.

After the third dive and snorkel site they serve afternoon tea consisting of tea and coffee and the yummiest banana cake you have ever had. At 2.45pm MV-Poseidon departs the reef and heads back to Port Douglas where it arrives at the Marina at around 4.30pm.

MV-Poseidon also offers Introductory Diving, so why not give it a go. All diving activities need to be prebooked as there are limited spots available. 

Swimming With Dwarf Minke Whales in Port Douglas - Early June to July.

During the winter months of June to July our tropical waters may present the added bonus of sighting Dwarf Minke Whales as these gentle giants migrate to mate and give birth to their young.

Our dive boat has been awarded one of only three permits to swim with these Dwarf Minke Whales and if they are around on the day you visit the Great Barrier Reef then you just may have the opportunity to hop in the water with your snorkel gear on and interact with these inquisitive whales.

Please note: swimming with whales is at the whale's discretion and not yours. Swimming with the whales is a bonus on this reef trip if they feel playful at the time you are enjoying your Great Barrier Reef tour - This is not a guaranteed activity, as it happens on rare occassions so you have to be very lucky at the time.

We are to abide by very strict guidelines and regulations with this permit and they are not actively allowed to pursue the whales or come within 300 meters of them.

The Dwarf Minke Whales have to be the ones to request the interaction with the boat by swimming over to it and showing interest in the snorkellers that are in the water holding onto a rope that is attached to the boat.

These whales have been known to follow the boat to the next snorkel and diving location so they can get a closer look at the humans in their territory. Ten snorkellers are in the water at one time and change over is every ten minutes so that all guests can have the chance to spend some time swimming with the Dwarf Minke Whales.

This is a diving and snorkelling tour and not a dedicated swim with whales tour.

See this page for swimming with whales.

Humpback Whales On the Cairns-Port Douglas Great Barrier Reef

Whale season is something you just do not want to miss especially when the giant Humpback Whales arrive in search of mates and to calve in the safety of the Cairns and Port Douglas Great Barrier Reef in the months of July to September.

Australia also has a very rare white Albino Humpback Whale that has been named Migaloo and he migrates to Cairns and Port Douglas nearly every single year to the delight of everyone in the tourism industry.

Film crews and photographers from all over the world come to Cairns and Port Douglas to capture his annual migration and antics.

It has also been reported that Migaloo has a son or daughter that is also an Albino and these may be the only two Albino Humpback Whales that have been identified in the world to date.

Please note: Whale season is changeable each year due to water temperatures and currents so the arrivals of whales may vary from one year to the next.

Our vessel was custom-designed to provide uncrowded snorkelling and scuba diving adventures.

The vessel boasts a number of great features including an air-conditioned saloon and open deck so you can kick back and enjoy your day on the reef.

Crew was really friendly and professional. The trip was really nice and we visit some amazing spots around the reef. We booked an intro dive which was just right, crew was not too helpful, thought, as the tanks were really heavy and someone can injure their back getting off the water as they not help you with that. Also I think groups are too big so you can miss some explanations and the education about the reef if you are not next to the guide. They should have more bilingual crew members.

Response From The Tour Specialists

Hi Paula, thanks for your feedback! The Tour Specialists team are pleased you enjoyed your time on the Outer Barrier Reef. Introductory diving can be a little daunting and the gear can be unexpectedly cumbersome but once you are under the water there is nothing quite like it which makes the experience all worthwhile. We will pass on your feedback to the crew however next time you visit please be sure to let us know of your language needs and we can ensure you travel on a day with a crew member who is bi-lingual. We look forward to welcoming you back to Port Douglas and the Great Barrier Reef soon.

Very professional but fun also. Good food and dive service/gear etc. 3 dives at 3 sites were a bit rushed but you could choose to do 2 if that is a problem. Rating the sites, 1st site 2.5 stars, 2nd site was about 4.5 stars third was 2.5 stars. Lots of bleaching and damage can be seen but still decent vibrant fish life. Very safety conscious also and dive guide was professional without being 'great'. Also this company was best price around to buy this tour.

Response From The Tour Specialists

Thank you Grant for your review of your Great Barrier Reef tour from Port Douglas. Very glad you enjoyed the day and we look forward to seeing you back in Cairns in the near future

I can highly recommend this trip. Staff were absolutely lovely, boat was well-designed, numbers were not too many and three separate sights gave plenty of snorkling time. I would definitely book with Poseidon again. A fantastic day!

Response From The Tour Specialists

Thanks for your feedback Emma. The Tour Specialists are pleased you had a great day on the Southern Ribbon Reef and enjoyed the smaller numbers on your reef cruise from Port Douglas. We hope to see you back again soon - maybe in Winter next time to see the Minke Whales.
