St Columba Falls State Reserve (295 ha), where the cascading waters of St Columba Falls plunge nearly 90 m from the Mt Victoria foothills to the valley of the South George River. The catchment area of over 4 000 ha guarantees a continuous flow of water down the granite cliff face.
The falls can be viewed from the carpark and a short walking track provides easy access, through a forest of tree ferns, sassafras and myrtle, to a viewing platform.
The intake bridge of a disused water race is located just off the approach road to the falls. It marks the starting point of a 45 km channel, constructed in the early 1930s to supply water for tin mining near St Helens. The intake pipes can still be seen on the northern side of the bridge.
