Situated close to Oudtshoorn, is one of the world's great natural wonders sculptured by nature through the ages - fascinating limestone formations in a wide variety of colours - the Cango Caves

The limestone beds of the Cango Group are, through movement in the Earth's crust, no longer in a horizontal plane. The layers of strata are also displaced laterally, forming dykes.

Rainwater, combined with acidic carbon dioxide from decomposing plant material on the surface, flows through a fracture zone. Limestone, i.e., calcium carbonate plus water and carbon dioxide = Calcium Bicarbonate - which dissolves in water, flows out.

This process of `cave making' takes millions of years.
