One of two signposted waterfalls in the Ku-ring-gai Wildflower Garden, Tree Fern Gully Falls is along the Mueller Track. It’s formed by Tree Fern Gully Creek plunging off a rock platform. You can get close to the top of the falls from the formal bushwalking track.
It’s far more impressive from the base of the falls, although this requires an off-track scramble down from the Mueller Track to the creek.
Getting to Tree Fern Gully Falls
The top of Tree Ferns Gully Falls is about 600m from parking near Caleys Pavilion, or 4km if you do the Mueller Tracl loop walk. There’s no walking track to the base of the falls, but you can continue about 200m down the main track, to find a rough pad that lead down to Tree Fern Gully Creek near the base of the falls.
