Johnston Falls is a striking waterfall on Wheengee Whungee Creek that plunges into a sheer-sided amphitheatre known as Shamash Deep. Large boulders scattered throughout the area hint at the enormous forces unleashed when the creek runs in flood.

The surrounding terrain is steep and rugged, and walkers seeking to pass the falls must navigate very steep scrambles further downstream, where surfaces can be treacherous; animal pads offer the safest routes through this challenging landscape.

From high on the western slope, views upstream reveal glimpses of Wheengee Whungee Falls and the towering cliffs of its eastern wall.

The falls hold historical significance as well — several researchers believe Johnston Falls, rather than Barrallier Falls on Christys Creek, was the point that turned back Francis Barrallier's 1802 expedition into the Blue Mountains.
