Located to the north of Canberra in Belconnen the Ginninderra Creek runs through a dramatic gorge with a 40 meter drop and then through a series of spectacular waterfalls. The falls were recognized in the 1930's as a possible tourist asset for the capital. Unfortunately the costs were deemed to be too great.
The Ginninderra Falls were once a popular swimming spot (on private land) now closed to the public I believe because of public liability concerns. Shame really...
