Dione Falls is the point where Upper Christys Creek plunges over a cliff edge at the lower end of Dione Dell, a small creek draining swampy ground near Kanangra Road in Kanangra-Boyd National Park, New South Wales.

The falls sit at roughly 1,000 metres elevation within Myles Gorge. The waterfall is a key feature of the Dione Dell canyon route, one of the easier canyoning trips in the Kanangra area.

Abseils descend beside or directly down the falls depending on water levels and the anchor option chosen. The surrounding quartzite rock can be slippery, particularly in wet conditions.
