Mount Kaputar National Park is a national park in Australia, surrounding the proximities of Mount Kaputar, a volcano active between 17 and 21 million years ago. It is located 50 km east of Narrabri and 570 km northwest of Sydney. Millions of years of erosion have since carved the volcanic region into the lava terraces, volcanic plugs, and dykes of Nandewar Range. The central feature of the region is Mount Kaputar, the park's namesake, which rises to an altitude of 1,510 m. The 360 degree view from the summit of the mountain encompasses about 1/10 of New South Wales' area or 80,000 km (31,000 sq mi).
