Rainbow Falls is a waterfall on Parchcorn Hollow Branch in Cannon County, Tennessee, in the Interior Plateau region, with a total height of about 30 feet. It lies about 5.4 miles east of Woodbury and roughly 23.1 miles east of Murfreesboro as the crow flies.
At 30 feet it is taller than the typical Tennessee waterfall of about 30 feet, ranking 136th of 332 with a recorded height. The water comes down as a cascade, descending over a series of rock steps rather than in a single drop.
The Interior Plateau is a rolling limestone landscape of pasture, oak-hickory woodland and cedar glades in Kentucky and Tennessee, riddled with springs, sinkholes and caves. Waterfalls drop over limestone ledges and in karst valleys.
