Time Out says
The coastal region close to the Great Ocean Road is ravenous with waterfalls, and Erskine Falls is certainly one of the best. Located a short 10km drive from Lorne, this thunderous waterfall plunges about 30 metres down into the gully of the Erskine River. You can view it from two lookouts: the upper lookout is an easy five minutes from the car park, and the lower lookout is a steeper descent to the base of the falls. For the adventurous types, there’s a 23-kilometre hike that takes you past a few smaller falls near Erskine as well.
