The Outer West is the huge area of Sydney to the west of the cities of Parramatta and Holroyd, which is the boundary with the Inner West. It is south of the Shire of Baulkham Hills, which is part of Sydney North West. It includes the cities of Blacktown, Penrith and Hawkesbury. Penrith is fast becoming the center for Outer Western Sydney business and night life. Blacktown and St Marys are also close behind and well worth mentioning. Richmond and Windsor in the City of Hawkesbury are famous for their history. Further west is the Blue Mountains and to the south Fairfield and Liverpool.
Road access from Sydney to the Outer West is via the M4 motorway, which is accessed from Parramatta Road, the main western exit from the CBD. The M4 connects with the M7 Westlink motorway, which in turn connects to northern Sydney's M2 and southern Sydney's M5.
Access from the Blue Mountains is via the Great Western Highway which traverses the mountains to cross the Nepean River just west of Penrith or the Bells Line of Road which terminates after crossing the Hawkesbury River at Richmond. Access from Singleton and the Hunter Valley is along the Putty Road which terminates at Windsor. The Northern Road provides access between Penrith and Camden/Campbelltown to the south.
Catching a train on the Cityrail  can be a way accessing the outer west for travellers. All trains stop at the major centres of Parramatta and Blacktown, before proceeding either to Penrith or Richmond. Express services to the Blue Mountains can be a much quicker way of getting to Penrith, if you are central around the time one is leaving.
