The Itinerary in Detail

Once you board the Poseidon catamaran, you’ll immediately notice the focus on comfort and safety. The vessel, measuring 24 meters, is tailored for smaller groups (up to 65 guests), which means you’ll likely enjoy a more intimate experience and better interaction with the crew and guides.

Departure from Port Douglas

The trip typically departs in the morning, with timing depending on your booking. The boat’s smooth, stable ride out to the reef is a highlight itself, thanks to the vessel’s design and the calm seas often enjoyed in this part of Queensland.

The Reef Stops

The fun begins once you reach the Agincourt Ribbon Reefs, known for their crystal-clear water, vibrant coral formations, and diverse marine life. You’ll visit three different reef sites, each selected for their visual and ecological richness. Reviewers mention the variety of sites, which keeps the experience fresh and interesting, whether you’re snorkeling or diving.

Each reef site is chosen for its ecological diversity and scenic beauty, so you’ll see different coral types and marine species at each stop. Expect to find colorful fish, sea stars, and maybe even turtles. The guided snorkel tours are free and come with marine biologist guides who help you understand what you’re seeing—“Fern,” the onboard marine biologist, was praised for her engaging presentations.

Snorkeling and Diving

You can enjoy up to five hours of reef time spread across the three sites. For first-timers, the vessel offers up to two guided dives with an instructor, making the experience accessible and safe.
