Marrong Reserve, also called Pemulwuy Lookout and Ridgeline Reserve, is a nature reserve, an urban park and a recreational lookout situated in Western Sydney, New South Wales, Australia. J-shaped, the reserve is located approximately 9 kilometres (5.6 mi) kilometers west of the Parramatta, and 33 kilometres (21 mi) north-west of the Sydney CBD. Due to its cultural and historic landscape importance, Mar-Rong Reserve was added to the NSW State Heritage Register on 17 October 2003. The reserve is visited for walking, exercising, natural scenery, picturesque views, birdwatching, ball games, and bush tucker.
Mostly aligned with Daruga Avenue at Pemulwuy and stretching to Lower Prospect Canal Reserve in the south, the reserve features a panoramic viewpoint that provides views of the Sydney skyline and the Blue Mountains. It is a popular vantage point for the New Year's Eve and Australia Day fireworks. Educational and interpretive information is present within the Reserve. Much of the reserve, excluding the parkland areas, is categorised as Natural Area-Bushland. Marrong Reserve and Prospect Hill are closely connected as a ridge, but are separated at a saddle by Butu Wargun Drive. The reserve features three precincts, which run from north to south: Marrong Reserve North, Marrong Reserve 'Saddle Bund' and Marrong Reserve South.
