This 5 km walk follows the popular Blue Gum track, with a focus on the Hornsby diatreme, one of three overlapping basalt breccia pipes that cut through bedrock in the early Jurassic. Originally several hundred metres above today’s landscape, erosion removed the overlying rock and cut through the softer breccias to form a wide, deep valley. Rich soils now support a majestic blue gum forest with rainforest understory, in marked contrast to the nearby sandstone ridgetop woodland.
