Marramarra National Park

The park is bounded by the Hawkesbury River in the north; Berowra Creek in the east; and private land to the south and west. The national park may be accessed from Wisemans Ferry via the Old Northern Road or from Hornsby via the Galston Road through the Galston Gorge.[2]

The park is administered by Ku-ring-gai Chase National Park. It offers bushwalkers a wide range of environments, from the mangrove communities along Marramarra Creek to the drier, sclerophyll scrub along the ridges. Access is provided predominantly by fire trails and service roads, frequently alongside power lines, with no dedicated walking tracks.
