The Blue Pools is a popular snorkelling spot at Heron Island, but is also a wonderful place to dive. While snorkellers generally limited themselves to the sheltered cove in the reef, divers are free to explore the sloping coral reef and numerous gutters, ledges and caves. Going no deeper than 15 metres divers will find the Blue Pools alive with fish life, including anemonefish, triggerfish, sweetlips, snappers, butterflyfish and schools of hussars. This site also has pretty hard corals and is a good location to see whitetip reef sharks. Other species seen at Blue Pools include turtles, stingrays, mackerel and barracuda.
