Discovering the Outer Great Barrier Reef with Quicksilver from Port Douglas
If you’re heading to Port Douglas and eager to see one of the world’s most stunning natural wonders, the Quicksilver Great Barrier Reef Snorkel Cruise offers a comprehensive day packed with marine adventures. Priced at around $220.35 per person, this full-day tour of approximately 8 hours takes you out to Agincourt Reef, one of the most accessible and vibrant sections of the outer reef. The experience includes a high-speed catamaran ride, multiple ways to explore the reef, and a delicious buffet lunch.
What we particularly enjoy about this tour is the combination of quality equipment and expert-guided activities. The included snorkeling gear, lycra suits, and buoyancy vests make floating among coral and fish easier for everyone, while the optional guided snorkeling tours led by marine biologists add an educational touch. The semi-submersible tours and underwater observatory allow non-swimmers to marvel at the underwater world safely — a thoughtful feature for families or less confident ocean-goers.
One possible consideration is the crowd size, as reviews mention the tour can get busy, especially during peak seasons. While the organization is generally praised, some travelers found the snorkeling areas somewhat limited for those who want more space to explore. It’s worth noting that the price includes most activities and meals, which makes it good value for a full day of diverse marine encounters.
This tour suits families, first-timers, and anyone who wants a comprehensive reef experience without the need to organize multiple excursions independently. It’s especially ideal if you’re looking for a guided, hassle-free day with options to customize your reef adventure.

A Detailed Look at the Quicksilver Reef Tour

Enjoy being on the water? Here are other boat experiences we've looked into in Port Douglas
Starting Out: The Journey to Agincourt Reef
Your day begins at the Crystalbrook Superyacht Marina in Port Douglas, with a 9:00 am departure aboard a luxurious high-speed catamaran. The 1.5-hour cruise to Agincourt Reef is a highlight in itself — a chance to relax on sun decks, sip tea, and watch a snorkeling demonstration that prepares you for what’s ahead. The boat’s modern design and ample space make the trip comfortable, even during busy seasons, though some reviews suggest a slightly larger vessel might improve the experience when crowded.
The journey across Cairns’ tropical waters offers scenic views, and you often spot seabirds or even dolphins. It’s a good time to settle in and get excited about the day ahead, knowing you’ll soon be in one of the world’s most iconic marine environments.
Agincourt Reef: Your Base for Marine Exploration
Arriving at the Agincourt Reef pontoon, you step onto a floating platform that serves as your base for about 3.5 hours of reef exploration. The reef here is located on the outer edge of the Great Barrier Reef, renowned for its consistent water clarity and biodiversity.
The highlight for many is simply padding into the water from the submerged platform with your snorkel gear, floating above coral gardens teeming with tropical fish. You can spend this time freely swimming, or join a guided snorkeling tour led by a marine biologist. Several reviews praise these guides for their knowledge and patience, often citing it as a memorable part of the day: “The staff are fantastic, very friendly and helpful,” noted one traveler.
For non-swimmers or those preferring to stay dry, the semi-submarine provides an underwater tour with commentary, offering close-up views of coral formations and reef life without getting wet. Many reviewers appreciate this option, mentioning how it makes the reef accessible for everyone.
The underwater observatory further enhances the experience, allowing you to relax in sheltered comfort while watching schools of fish and graceful rays swim past. Some note that the reef area can feel somewhat confined, but this is primarily for safety and environmental protection reasons — the reef’s delicate ecosystem requires careful management.
Customizing Your Reef Day
The tour’s real strength is the array of optional activities. These come at an extra cost but are well worth considering if you want a richer experience. You can opt for an introductory or certified scuba dive — a chance to see more of the reef’s depths. Many reviews highlight the quality of the dive guides and the safety measures, making it suitable even for beginners with proper instruction.
Adding the Ocean Walker helmet dive is another popular choice, giving you the chance to walk along the seafloor with a helmet that keeps you dry and allows you to breathe normally. It’s a hit with those who want a closer look but aren’t comfortable with traditional diving.
For the adventurous, a 10-minute helicopter flight offers a bird’s-eye view of the reef, providing unforgettable panoramic photos and a sense of scale that’s hard to match from below.
Dining and Relaxation
The onboard buffet lunch is another highlight, with many reviewers praising the freshness and variety of dishes. It caters to most tastes with tropical fruits, salads, seafood, and hot options. Snacks and afternoon tea are also served, so you’re well-fed for the duration. Many mention that the generous portions and quality help sustain energy for more reef exploration afterward.
