The Agincourt Reefs are “ribbon” reefs that run parallel to the Continental Shelf and the Coral Sea Trench. This geography means they’re among the Great Barrier Reef’s most pristine ecosystems. The Agincourt Reefs are great diving spots as they include a huge wall dive at Blue Wonder, interesting channels and caves, and pinnacles where fish feed. Snorkelers can also enjoy many of these sights from the surface of the sea.
Most travelers get to the Agincourt Reefs on a day tour from Port Douglas or Cairns. These can include diving and snorkeling. Some boats have underwater observatories. Another way to experience the reefs is on a scenic flight, which will give you a different perspective of the area.
