[1][2] It is located near Bacchus Marsh and is used by bushwalkers and rock climbers, who are attracted to its views and geological features.

[citation needed] The 200m deep gorge was formed about a million years ago when movements along a fault in the Earth's crust steepened the river's gradient.

Other geological events that have since occurred include the advance and retreat of an ice sheet and the inflow of volcanic lava.

Werribee Gorge State Park is about 8 km west of Bacchus Marsh and can be approached by two routes.
