About this place
What to expect
Coral Canyons is a marine site on Heron Reef near Heron Island that showcases the reef's underwater terrain and abundant sea life. It is one of several world-class dive and snorkel locations around the island and is known for its series of shallow canyons that cut into the edge of the reef. The canyons are filled with tropical fish, turtles and reef sharks, and provide a dramatic underwater landscape for snorkellers and divers. Along the coral ridges, groups of reef squid are often seen hovering in the clear water, shifting colour as they move. Heron Island sits directly on the Great Barrier Reef and offers easy access to this and other reef sites. Snorkelling tours and dive trips take visitors to Coral Canyons and surrounding reef areas, where the diversity of coral formations and marine life is a highlight for many.
