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 (31 mi) east of Narrabri and 570 km (354 mi) 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 (4,954 ft).
