Varmint Cave Falls is a 15-foot free-falling waterfall found 0.15 mile up a western tributary of Low Gap Creek, which joins the creek between Low Gap Creek Falls and Crescendo Falls. It features an interesting grotto large enough to house a varmint or two and can be visited as a bushwhack side trip on the way to Crescendo Falls.
