Overview
The lowermost waterfall on West Fork Campbell Creek, Keyhole Falls drops about 15 feet into the best swimming hole on the creek. The creek flows in a C-shape at the falls and you can’t see all of it from a single vantage point. From the base, you can see only the last section squeezing through a notch in the rock.
See the Hike Description and Overview section for West Fork Falls for more information.
