Knowles Cave - SA

Knowles is just one of the many caves in this karst limestone environment, however Knowles is a worthy visit as it is one of the more accessible caves in the entire region and will give you a good sense of the what lies beneath the seemingly empty barren plains. Many of the caves on the Nullarbor are very dangerous and impossible to access without permits and specialised caving and abseiling equipment. Knowles Cave however is an easy walk-in, being an elongated doline. The whole Nullarbor is one giant piece of limestone and anywhere that you can find a bit of limestone you will find karsts. At Knowles Cave, you will easily see these karsts, which appear to have fossilised marine life trapped within. Embedded into the rocky entrance to the cave look out for shells locked into the rock, along with imprints where the shell used to be.
