The Gulch is a thrilling drift snorkel through the deep channel between Barren Island and Child Island, 7 km east of Great Keppel Island in the Southern Great Barrier Reef. Strong tidal currents sweep through this narrow passage, attracting large pelagic schools and making it one of the most exhilarating snorkel and dive sites in the Keppels. The channel's rocky bottom is lined with colourful fringing coral reefs, while the deeper waters draw Spanish mackerel, tuna, trevally, and the occasional manta ray or wobbegong shark. This is a spot for confident swimmers seeking big marine encounters in a wild, open-ocean setting.
