It’s not only this hill, it’s all around, mostly private land. The Castle Hill Scenic Reserve allows shorts walks along the sculptures, a welcome interruption from our journey.
How are these sculptures created? They’re made of limestone, acid present in rainwater works on joints in the soft rock, gradually enlarging them. Small differences in rock structure and solubility cause a wide range of fluting, pits and grooves. These sculptured landforms are the result.
