Features

The NSW National Parks and Wildlife Service (NPWS) opened their depot in Bucketty in 1993 and commenced managing the newly established Yengo National Park. A helipad, known as 'Bucketty International' was established and in 1995 a fire tower was built, following severe fires in the area. In 1999 the NPWS acquired parts of the Crown land that lay between Bucketty and the Yengo National Park. This new area also included the Convict Wall and the amphitheatre used by the community. The Bucketty community asked NPWS to recognise their custodianship of the place and in early 2000, the community, together with the NPWS, developed a Memorandum of Understanding to jointly manage the site. Access to Yengo National Park is via Yengo Creek Road off the Great North Road, near. The park is bounded in the east by the small settlements of Bucketty and ; in the north by Wollombi Brook; in the west by the Putty Road, the settlements of and, and the Mellong Range; and in the south by the Parr State Conservation Area, the settlement of , Webbs Creek, Mogo Creek, the Hawkesbury River, and the Dharug National Park. The course of the Macdonald River flows from the northwest of the national park towards the southeast, where it reaches its confluence with the Hawkesbury River.
