St Columba Falls is in the rainforest of the Pyengana valley, around 50 km west of St Helens. A short, well-built path through tree ferns and myrtle leads from the car park to a viewing platform at the base of the falls; the spray is heavy, so expect to get wet.
Combine with a stop at Pyengana Dairy (cheese tastings and a good café) and the Pub in the Paddock at Pyengana, an isolated old wooden pub famous for its beer-drinking pig. The Falls Road branches off the A3 highway from St Helens — sealed all the way.
