Lake Wabby is surrounded on one side by the massive Hammerstone Sand Blow and on the other side by eucalypt forest. This is an example of a barrage lake, formed when a creek became blocked by a shifting sand dune causing the water flow to be dammed. Its emerald green waters are home to 13 species of fish. Access by foot from the eastern beach is 45 minutes.
Lake Wabby, emerald green in colour is unique to Fraser Island.
