Abercrombie Karst Conservation Reserve

Abercrombie Karst Conservation Reserve is a protected karst area in the Central Tablelands of New South Wales, about 40 kilometres south of Oberon near the Abercrombie River. Managed by NSW National Parks and Wildlife Service, it is renowned for its limestone cave system featuring The Archway, the largest natural limestone arch in the Southern Hemisphere. The reserve offers guided cave tours, camping, bushwalking and historic gold-mining relics within a scenic forested valley.

Visitors can explore a limestone karst landscape with extensive cave systems, including the massive Archway cave with natural arch and historic formations. The reserve offers guided cave tours through illuminated chambers, self-guided surface walks, forested valleys along Grove Creek and Abercrombie River, a campground with creek swimming holes, picnic areas, and remnants of 19th-century gold mining. Expect uneven terrain, steps inside caves, and a quiet bush setting.
