Borenore Caves

The Borenore Caves, contained within the Borenore Karst Conservation Reserve, are a series of limestone caves that are located in the Central West region of New South Wales, Australia. The caves are renowned for their karst qualities, namely the numerous fossils from a long-lived reef complex from the Silurian period. Fossils include corals, crinoids, brachiopods, gastropods, pentamerids, colonial tryplasmids and trilobites. Borenore's karst is surrounded by igneous rock that flowed from volcanic eruptions at nearby Mount Canobolas. The 136-hectare (340-acre) reserve is situated 17 kilometres (11 mi) west of Orange, and is registered as a natural heritage site on the Register of the National Estate for its large diversity of karst morphological and sedimentological features. Camping in the reserve is not permitted.
