Walk: Blue Gum Diatreme and Fishponds

Registration essential

Emydura turtlesThis route captures in a single bushwalk the maximum possible diversity to be found in North Shore bushland. It begins in the blue gum forests of the Hornsby diatreme of volcanic rocks and rich, deep soils. It leaves the blue gums to follow a deep, forested sandstone valley down to Fishponds Waterholes (made famous by local artist Jimmy Bancks of the long running Ginger Meggs cartoon strips). The waterholes feature common Emydura (Macquarie River) turtles (see right) and not the usual longnecks. The walk turns left at Fishponds to follow Berowra then Waitara Creek upstream to cross at the striking, potholed waterfall the locals call 'the washtubs'. The washtubs lead to a succession of stepped sandstone ascents through shrubland and heathy woodland before returning through the tallest and most beautiful of the diatreme forests backed by the sheer sandstone wall of the diatreme margin itself.
