The You Yangs Regional Park is a park in southern central Victoria, Australia. The park encompasses much of the southern areas of the You Yangs, a granite range that rises from the Werribee Plains, 60km southwest of Melbourne. The park is operated and managed by Parks Victoria and is open during daylight hours.
Situated within the traditional boundaries of the Wathawurrung (Wathaurong/Wada Wurrung) Aboriginal tribal lands and once home to the Yawangi Baluk (local clan whose territory extended to the Port Philip bay), the You Yangs (Wurdi-Yawang) shares historical significance with Australians of non-indigenous origin.
A road known as Great Circle Drive, encircles Flinders Peak, enabling drivers, cyclists and walkers to navigate the undulating terrain, from flat forested areas to hilly scenic views. The road passes by many lookouts, rest areas, picnic areas, barbecues and other features.
