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.

The crew was very friendly and very accommodating. Louise was really it understanding and helped reschedule one of the members in the group due to last minute sickness. The plantoon was a lot of fun well organized and clean. Helmet dive was fabulous. So was the scuba and snorkeling.

You can really tell Quicksilver is a well-established name in the Port Douglas diving and snorkelling scene. Everything was incredibly well organised, from the uniforms right through to the catering. Add to that a professional fleet of mini and stagecoach buses and four sleek, impressive vessels, and it all runs like clockwork! This was my first time diving the Great Barrier Reef, and the experience was made even more memorable by the friendly, accommodating crew. Huge thanks to Cpt. “Sharks” for the no-nonsense headcounts, Queenie for the great chats, Leah for the constant positivity, and “Gordo” for making it feel like I was diving with a longtime mate rather than just a dive master. Merry Christmas and Happy New Year 2026!

Booked 3 dives to the Great Barrier Reef as a solo female traveller, had the best day ever!! Went on a silver sonic cruise with Gordon as my dive master who was great, felt so safe and had a great 3 dives - they sorted all equipment efficiently and catered food/drinks, super friendly helpful staff. 10/10!! Would recommend if you want to dive or snorkel the reef!!

I took this trip because it was recommended by friends and it was...fine. It feels very big and impersonal, a couple of hundred people on each trip I think. It takes an hour and a half to get out to the reef, during which they try to sell you various paid extras like guided snorkels, helicopter trips, camera rental etc. Once you're out there you're snorkelling in a marked off area from the pontoon and there were a lot of non-swimmers on the trip flailing around in the water with no awareness of where their fins were going, which probably explains why the coral here was less than stunning. They sell the outer reef trip as being the best option but I visited the inner reef at a less heavily exploited site a few days later and it was way better. Lunch provided was good, boat departed on time, everything worked fine, if you're not going any further north this is probably a fine option.

Fast & stable catamaran ride out to reef. Good setup for snorkeling & diving for quick water entry-very efficient. Somewhat limited snorkel area -but due to wind & currents probably smart with many beginner snorkelers. Good buffet spread aboard - lots of choice. Nice also that they have the sub experience for elderly or children. Quicksilver also offers a helicopter tour of reef as an add on -others don’t- so more options to do. We chose not to do the helicopter reef tour, but to take the discounted helicopter ride back to Port Douglas in mid afternoon instead when they take the helicopter back for the day. That was a longer ride with awesome reef views and a ride along the Daintree coast with a landing very close to our resort south of Port Douglas. It made our trip even more spectacular - highly recommend!!

Turtles. Swimming with those alone was worth the trip, the expense, and the high rating. Quicksilver is a massive outfit. They have been doing this for decades. They know what they are doing. It's difficult to ignore the fact that you are part of big business here. There's a lot of upselling. However, everyone is very friendly and helpful, no one is pushing you to spend more money, and it's obvious that thecstaff is well trained. If you are not in the market for extra expenditure it's easy to ignore and focus on the experience. Everything is extremely well organized. I had feared there would be long queues with hundreds of people on the trip, but eveeything went very smoothly, no waiting times, at least for us. The snorkeling itself is obviously world-class. You are guaranteed to see an abundance of marine life, and with some luck and patience you will see turtles or sharks. The snorkeling area is rather big, but even so you are likely to bump into other swimmers. Can imagine that during peak season the waters might be quite crowded. Anyway, this was definitely a "must do" experience, snorkeling the Great Barrier Reef is a unique exoerience, and I can't imagine many other companies do it better.
