Ozone Falls State Natural Area is located in Ozone, TN on the Cumberland Plateau in Cumberland County. It is easily accessed from I-40 at Exit 338 (westbound) or Exit 329 (east bound). The falls are on Hwy. 70, 4.4 miles west of Westel Rd. or 4.6 east of Crab Orchard Rd. There is a small parking area at the trailhead. With a plunge of 110 feet, this is a very impressive waterfall. The day I was there was two days after a heavy rainfall.
