It is reached from a small car park off Tills Rd.
It is the site of the alluvial gold mining of the 1880s - the only relics are the overgrown diggings.
The Black Flat Circuit Track is a 4 km loop, through the former diggings, along the Nature Trail, and passing the Yarra River. Part of the Track follows the Jumping Creek to Black Flat Walking Track.
The Track passes the site of the Mullen's Orchard, which operated from 1870 to 1914, adjacent to the Yarra.
There are picnic tables at this point, which is used as a canoe launching area.
For the adventurous, a rough foot-track goes from the orchard site westerly through bushland along the river bank, but becomes overgrown near the old watercourse. This links with another track which joins the management road. The remains of old concrete foundations are visible in a cleared area at the end of this track.
I walked the Black Flat Track on Friday afternoon July 10, 2009, a dull and overcast midwinter day!
