Harvey to Collie River Valley Scenic Loop
Take the scenic route from Harvey to the Collie River Valley and be awed by stunning hills and forests.
From Harvey, head south on South Western Highway until you reach Mornington Road (6.2 kms). Mornington Road winds its way up the Darling Range, providing magnificent views of the Swan Coastal Plain and the Harvey Region.

Local Tip: For a shorter drive, after travelling along Mornington Road for 23 kms, turn right onto Gastalo Road. Note: Worsley Alumina South 32 bauxite mine will be located on your left.
