Quicksilver Cruises
Departing from Port Douglas, your 90-minute high speed catamaran takes you directly to Agincourt Reef. The permanent pontoon moored here provides a sheltered base. During the trip a snorkeling demonstration will get you ready for your adventure, and the staff will take you through your options for the day.
Agincourt Reef
You'll have around 3.5 hours to enjoy the reef at your leisure. Grab a snorkel and fins and hit the water on your own, or join an optional guided snorkeling tour with a qualified marine biologist. Snorkeling is a great way to explore the Great Barrier Reef, and there are friendly staff on hand to show you how. Prefer to stay dry? You can explore the stunning reef from the comfort of a semi-submersible submarine. You'll take a leisurely cruise through colorful coral gardens, giving you a snorkeler's view of the marine life without getting wet. For a little more adventure, why not try an introductory scuba dive. or a unique Ocean Walker Helmet Dive - no diving experience necessary. We recommend you book this reef trip on your first full available day. You then have the opportunity to be flexible and change your travel date if you wish. Your booking can be changed at no additional cost directly with the operator once you are in Cairns.
Full day reef cruise - 15% off: 3.5 hrs of snorkeling, swimming or coral-viewing tour on the Outer Great Barrier Reef. Includes buffet lunch, snorkel gear

A nice experience to get up close to the largest/ longest coral reef. Very well organised and good service by the team.

It was amazing! My husband and I are not swimmers but wanted to try snorkeling. The lifeguard spent a lot of time getting us comfortable with the equipment and teaching us how to snorkel. After that we spent over an hour snorkeling and a lifeguard was always keeping an eye on us. This is a very well run operation. Started on time and all the other activities ran smoothly. Lunch was fine, tea was decent too. Marine biologist’s presentation was very interesting. Highly recommend!

The boat is large and comfortable from Port Douglas to Agincourt Reef. I didn’t realize that the Great Barrier Reef is a series of reefs stretching along Australia’s coast – and Agincourt Reef is spectacular. The platform at the reef accommodates snorkeling for experienced to “never done this before” guests. The submersible boat allows a dry version of seeing the reef, fish, and turtles. For a fee there’s a helicopter tour of the reef that allows you to appreciate the scale of reef. Food & drink are available on the platform

I can’t recommend this enough. Worth every Penny, all of the crew are so friendly and helpful, they really want you to make the most of your trip. There are activities suitable for beginners/non swimmers who are still made to feel safe enough to snorkel should they wish to (but have an underwater viewing area and submersible boat trip if they don’t’!) right up to experienced divers. The lunch was good too with lots of veggie options amongst others.

Travelled with family from overseas that were not swimmers. Between the semisubmersible and the ocean helmet walk, there are a few things to do. The cruise ticket includes Lycra suit, flippers, snorkel and mask hire, as well as the semisubmersible. The add-ons that are worth paying include scuba and helicopter ride.

We joined this excellent catamaran trip out from Port Douglas to Agincourt reef on a pleasant 90 min boat trip. There's a secured pontoon over the reef where you spend around 3 hours on a range of activities. It's busy if you stay dry with semi submersible trips and a little plastic viewing tube. Lunch is great buffet style and you can sit on deck with a beer. Snorkeling was excellent they kit you out with everything including stinger suits and give you a briefing The staff are plentiful, hilarious and diligent. A great day out for those staying dry and novice snorkellers like me. I'd imagine the experienced might want a smaller bespoke experience but for us amateurs they really made our day. Oh and I get seasick but felt fine all day sitting outside on deck and taking a Kwells first, which they sell on board if you need one

Great day out at the reef, this is our 7th trip with Quicksilver. Staff are friendly and knowledgable, lunch is delicious and the boat is comfortable. A definite must when in Port Douglas.

We’ve had quite a few reef trips, some that have been disastrous weather wise and the tour still ran. Any of these tours should only be booked if you know how the weather is going to be including the swell and current. We picked a perfect day weather wise. There is a photographer going around at the reef however a video of the day with snippets of reef life all set to music, would be a better reminder of the tour. There also was better food offered for afternoon tea previously (cake was offered) where now it’s biscuits for morning and arvo teas. The lunch has too much marinated in ethnic species which is a bit off putting for those with simpler tastes. Overall a good tour but improvements can be made to encourage repeat customers.
