The 3,050-hectare (7,500-acre)[2] national park is situated approximately 388 kilometres (241 mi) east of Melbourne and was declared in 1925.

The park is dissected by the Princes Highway, between Cann River and Genoa.

The park reserves examples of warm temperate rainforest, particularly the jungle of Mount Drummer.

Compared to the tropical rainforests of Queensland and New South Wales, this is a floristically depauperate forest, representing as it does the southern limit of this flora.

The rainforest community consists of a closed canopy of Lilly Pilly Acmena smithii with numerous lianas, ferns, and epiphytes.
