Legend has it that this limestone cave system was discovered when Kelly, a local farmer's horse, accidentally fell into one of the caves. The animal was never found, but while looking for it the search party learned that a veritable geological treasure lay underground the area. The Show Cave Tour gives a good insight into the caves. The most intrepid visitors can also go on the Adventure Caving Tour, a 2hr speleology expedition amid stalactites and stalagmites.
