Another Otway National Park wonder is Hopetoun Falls, a 30-metre-tall waterfall that plummets into the Aire River. Visitors can descend via a well-maintained set of stairs that lead to a viewing platform that’s within spitting distance of the foot of the falls. And when we say spitting distance, we mean it. Prepare to get wet. The walk is a one-kilometre return trip, which should only take about 30 minutes.
