Bargo River State Conservation Area protects a section of the upper Bargo River catchment in the Southern Highlands of NSW. The Bargo River drains into the Hawkesbury-Nepean system. The geography is rugged dissected Hawkesbury Sandstone, with open forest and woodland being the primary vegetation communities, although at Cave Creek there is a small section of Warm Temperate Rain Forest. There are a number of significant species of flora and fauna, some which are rare and threatened. Recreational activities include bushwalking, mountain bike riding and picnicking at the Cave Creek day-use area. A short bushwalking track leads from the day-use area to a sandstone cave through which a stream runs, exiting into a shallow gorge clothed in rainforest.
