The Borra Caves are a fantastic example of karst topography, where water slowly dissolves soluble rock to create underground passages, caverns, and speleothems. As acidic rainwater and river flow carved through the limestone, stalactites hanging from the ceiling and stalagmites rising from the ground evolved into breathtaking natural sculptures. Some formations take on shapes reminiscent of Shiva-Parvati figures, human brains, and even crocodiles, blending natural science with imagination.
