Overview
The outer reefs offer some of the best snorkeling and scuba diving on the Great Barrier Reef. This cruise sets sail for the Agincourt Reef, where you can snorkel amid colorful coral gardens, enjoy optional scuba dives (certified divers only), and tuck into a delicious seafood lunch onboard.
What to Expect

Make your own way to the marina in Port Douglas to meet your guide and board your boat—the luxurious Poseidon III, a high-speed catamaran equipped with an air-conditioned lounge and a lowering transom for easy access to the water. Admire the views from deck as you set sail across the Coral Sea and venture out to explore the more remote outer reefs.

Arrive at the first of three dive sites, located along the outer limits of Agincourt Reef. Depending on the tour option selected, either get suited up for your first scuba diving excursion (certified divers only) or jump in to swim and snorkel amid the vibrant coral gardens.

As you explore the reef, learn more about the UNESCO World Heritage­–listed Great Barrier Reef and its unique ecosystems from your marine biologist guide, and spot an abundance of tropical fish, marine life, and colorful coral formations.

You visit three different sites with various options for snorkeling and scuba diving. In between, relax on deck and take in the scenery as you enjoy a seafood buffet lunch. Morning and afternoon tea are also served onboard.

After a full day at sea, return to the mainland, where your tour ends back at Port Douglas.

Amazing day on the Reef

I couldn’t recommend Poseidon highly enough. We took a one day tour to three locations on the outer reef to snorkel and had an amazing experience. We were so impressed by the professionalism of the staff, in particular Shay who helped my 72 year old,...More
