Time Out says
Trentham Falls is located in the Hepburn Shire, near Daylesford and Hepburn Springs, and has the distinct honour of being one of the longest single drop waterfalls in Victoria. Head in after a good downpour and you’ll see water gushing some 32 metres over 40,000-year-old basalt cliffs. The falls are also very easy to get to. Follow signs to the Trentham Falls car park, then it’s just a short walk down a signposted path towards the viewing area.
