The Brickpit Ring Walk is an urban nature park and walkway that serves as a water storage and frog habitat, located in the Bicentennial Park, in the Sydney Olympic Park, in western Sydney, New South Wales, Australia. Once a brick manufacturing site, the land was to be redeveloped as part of the site for the 2000 Sydney Olympic and Paralympic Games, however the 1992 discovery of the then endangered Green and Golden Bell Frog ("Litoria aurea") placed a hold on developments. The urban nature park and walkway was established in 2006.
