Walk: Blue Gums in Hornsby Valley

  • When 17 Sep, 2017 from 09:15 AM to 12:30 PM (Australia/Sydney / UTC1008)
  • Add event to calendar iCal

This walk is remarkable for its scenic beauty and for the vegetation contrasts between tall Sydney Blue Gum forests, dry sandstone woodlands, tall sandstone valley forests and riparian rainforests. The reason behind the variety is the chain of Jurassic-age diatremes within the sandstone which carry basaltic breccias that break down to deep, fertile soils, creating a broad sweep of Blue Gum forested valley. The walk also descends to the deeply incised, meandering sandstone valley of Berowra Creek which hosts the famous Fishponds Waterholes. Look out for there eels, carp, turtles (Emydura not Chelodina), water dragons, plus swamp wallabies in surrounding bushland, not to mention a great variety of bird species including lyrebirds.
