The Channels is a thrilling snorkel site on Agincourt Reef, part of the outer Ribbon Reefs about 65 km northeast of Port Douglas. This site is famous for its network of swimmable coral tunnels and swim-throughs carved through the reef structure, allowing snorkelers to drift through narrow channels flanked by vibrant hard and soft corals. The terrain is a labyrinth of bommies, overhangs, and caves, with clear visibility and an abundance of colorful reef fish swirling around the coral formations. The dynamic tidal flow through the channels creates an exhilarating drift-style experience, making it a standout destination on the Great Barrier Reef.
