Cumberland Falls, sometimes called the Little Niagara, the Niagara of the South, or the Great Falls, is a large waterfall on the Cumberland River in southeastern Kentucky. Spanning the river at the border of McCreary and Whitley counties, the waterfall is the central feature of Cumberland Falls State Resort Park.
On average the falls, which flow over a resistant sandstone bed, are 68 feet (21 m) high and 125 feet (38 m) wide, with an average water flow of 3,600 cubic feet per second (100 m³/s).
Under a full moon on clear nights, an elusive lunar rainbow or moonbow is sometimes formed by the mist emanating from the falls.
