Barnard Grotto Falls is a waterfall on Christys Creek in the Kanangra area of New South Wales.

It sits roughly 300 metres downstream of Barer Falls and is one of several obstacles encountered in close succession toward the end of a canyoning descent of the creek.

The falls can be jumped, climbed, or slid, making them accessible to canyoners of varying confidence levels. Their character and setting make them popular enough that visitors often make repeat jumps.

The falls are part of a full-day canyoning route that also includes abseils and other water obstacles along Christys Creek.
