The track is so called, because an observatory was set up not far from the Woodford Academy, to house a 114mm telescope and other instruments, needed for the observation of the 9th December 1874 Transit of Venus.
The passing of Venus between the Sun and Earth, was an important event, as it enabled scientists to better calculate the distance from earth to the sun.
The most recent Transit of Venus occurred in June 2012, and will not occur again until 2117.
Along the way we passed Waratahs (Telopea) in flower, and visited Edith Falls (below right) and a side trip to Mabel Falls, where we ate our lunchs.
My thanks to Judith and Jenny for showing us this lesser known track, with its historic connections.
