Over a hundred Aboriginal sites have been recorded in the Hornsby region, with many of these in the Berowra Valley National Park and around the suburb of Berowra. The sites include engravings on sandstone ridges, rock shelters with cave paintings, open campsites and grinding grooves. The Aboriginal occupation of the Berowra Valley is thought to have been predominantly in the last 6,000 years (until European colonisation pushed them out), as the valley was deeper and steeper prior to the last ice age.
