Set out from Port Douglas to Agincourt Reef on a high-speed catamaran and spend the day snorkeling, viewing coral from a semi-submersible, or trying an introductory dive. This practical day trip is ideal for first-time reef visitors and non-swimmers.
More ways to explore the area's outdoor wonders
The catamaran slips from the marina and the ocean opens — a stretch of blue that dares you to look beyond the horizon. Within an hour you’re skimming toward Agincourt Reef, the outer edge of the Great Barrier Reef, where a permanent pontoon rests like a research station on the sea.
Difficulty
easy
Duration
8–9 hours
Fitness Level
Suitable for most fitness levels; basic mobility to climb ladders and transfer to the pontoon is required. Non-swimmers can participate with life vests.

Use reef-safe sunscreen
Wear a mineral-based sunscreen and a UV shirt provided on board to protect delicate coral communities.
Manage dive timing
If you plan to scuba dive, follow the recommended no-fly times—12 hours after a single dive, 24 hours after multiple dives.
Bring motion-sickness remedies
Even experienced travelers can feel rolling seas; take preventative medication or use acupressure bands if prone to seasickness.
Swimsuit and swim towel
Quick-change swimwear and a towel are useful for snorkeling and drying off on deck.
