About this site
Canyons is a section of the outer reef near Heron Island, reached by a boat ride from the island. Huge mounds of coral rise on either side, and narrow, miniature canyons lead through the coral between them.
Green sea turtles, white tip reef sharks and cow tail stingrays have been seen here, along with plenty of sea cucumbers. The canyons are fun to swim through, and the maze of channels is large enough that snorkellers have spent very long sessions exploring it without covering it all.
