Mount Imlay is a national park 387 km south of Sydney, named after the Imlay brothers, who were early pioneers in the NSW south coast district. A peaceful pocket of remote bushland, narrow rocky ridges and deep gullies, Mt Imlay National Park is accessed from the Princes Highway, south of Eden, New South Wales.

The top of Mt Imlay offers great views of the coast and forest, and the summit area supports a population of extremely rare Eucalyptus imlayensis. Aboriginal people know the mountain as Balawan, a powerful spiritual place of great significance. The mountain is named after the three Imlay brothers, who played an important part in opening the Eden-Monaro district to European settlement in the 1830s and 40s.

Mt Imlay National Park forms part of a system of national parks and reserves that protect the coastline and ranges between Moruya and the East Gippsland region of Victoria. These parks include the adjacent South East Forests National Park, Eurobodalla National Park, Mimosa Rocks National Park, Bournda National Park, Bournda Nature Reserve, Ben Boyd National Park, Nadgee Nature Reserve, along with Croajingalong National Park and Cape Conran Coastal Park in Victoria.
