Bulcamatta Falls is a small waterfall tucked into a fern-lined rainforest gully on Burralow Creek, within the Lower Grose Valley area of Blue Mountains National Park, New South Wales.

It sits near Kurrajong Heights off the Bells Line of Road, reached via an easy out-and-back track of roughly 2. 4–2. 7 km return from the Burralow Creek campground.

The route passes a convict-dug pit, follows the creek, and winds through a narrow, shaded gorge before arriving at the falls and their surrounding grotto of ferns. The falls are modest in scale but notably atmospheric.

By night, the site hosts one of the larger glow worm colonies in the region, with thousands of tiny blue lights illuminating the grotto — a spectacle that draws visitors specifically for after-dark walks.

The surrounding peat swamps also provide habitat for the nationally endangered giant dragonfly in summer.
