Geology research and conservation
Through geology management programs, NSW National Parks actively conserve the state’s caves and karst environments, including Jenolan Caves and Wombeyan Caves.
Inspiring landscapes and geology
NSW national parks' karst environments are among the oldest and most complex in the world. Exposed rock, geological features, and decorative caves of extensive karst systems make up some of the most inspiring landscapes in NSW national parks. Enjoy the visual treasures of Jenolan, Wombeyan, Yarrangobilly and Abercrombie caves. Enormous cliff faces and waterfalls display the geology of Blue Mountains. Further afield, you can explore volcanic landforms at Warrumbungle and Mount Kaputar national parks, as well as the Aeolian features of Mungo National Park.
