Lime Rock Falls is a 15-foot cascading waterfall located downstream from Huckleberry Falls and Tumbling Rock Falls, below where those two respective streams converge into a larger one at Browns Bottom Road. Lime Rock Falls is located close to the Middle Fork Broad River and entails a 0.3-mile bushwhack to reach, as there is no trail to it.
