Glenworth Valley is in the Central Coast region to the north of the Hawkesbury River itself to the north of the city of Sydney, Australia. Popran Creek flows through the valley which includes parts of the suburbs of Glenworth Valley and Mount White. Popran National Park was created in 1994 and is for the most part made up of sandstone cliffs and gullies. The creation of the park is indicative of the value the area has because of its unique indigenous and early European history, fauna, flora and geology. The Park takes its name from Popran Creek which rises in the locality of Central Mangrove and then flows for approximately in a mostly southern direction till it reaches Mangrove Creek.
