Guy Fawkes River National Park, Nature reserve in New South Wales, Australia

Guy Fawkes River National Park is a nature reserve in New South Wales that spans across elevated plateaus and lowlands between two major geographical regions. The landscape features deep river gorges, rocky outcrops, and varied vegetation zones shaped by the different elevations.

The park's wild horses, known as brumbies, have lived in the area since the 1930s; many descend from Saladin's horses, as their dun coats show. In October 2000 the NSW National Parks and Wildlife Service shot more than 600 brumbies from a helicopter, a cull that drew public outcry. A 2002 heritage report found the horses had historical, military and cultural value as descendants of Australia's Waler cavalry horses. In the 1970s the Bicentennial National Trail was plotted along the western side of the Guy Fawkes River on an old travelling stock route.

The park contains historical links to Australian military heritage through its horse population, descended from cavalry horses known as Walers.

The park can be accessed through Waterfall Way near the village of Ebor, which serves as the main entry point. Several pathways lead to viewpoints and water features where visitors can explore the river system and surrounding terrain.
