Spring Mount Conservation Park, formerly the Spring Mount Wild-Life Reserve, is a protected area in the Australian state of South Australia located in the localities of Hindmarsh Valley and Inman Valley about 57 kilometres (35 mi) south of the state capital of Adelaide.

The vegetation is an open forest of Eucalyptus obliqua and E. baxteri with a mid-dense understorey comprising a great variety of sclerophyllous shrubs. Macropus fuliginosus (western grey kangaroo) is common in the park, which has at least five other native mammal species…
