Ozone Falls Section

Ozone Falls Section


Grassy Cove Segment


Distance: 6.7 miles

Difficulty: Strenuous

Elevation Change: Max EL 2730; Min EL 1407; Total Gain 976; Total Loss 2069

Elevation Profile:

Cautions: There are steep climbs and descents. Some are difficult requiring the hiker to clamber down or up stone steps or rocks with no handholds. These can be icy in winter. There is no bridge over North Fork Basin Creek. There are numerous old roads crisscrossing the area covered by this section. The trail takes advantage of these sometimes for short distances. At other places the roads make confusing intersections. Watch carefully for the white blazes to avoid hiking off down a roadbed away from the trail. The final ascent from Ozone Falls to the US 70 parking area is precarious in places.

There are no safe water sources along this section of trail. Bring your own drinking water or filter and sterilize water for drinking; boil or sterilize all water used for cooking.

The peaks and flanks of the mountains can expose the hiker to high winds at times. In winter, it’s best to dress in layers because the hiker will dip into gorges that can be calm and feel warmer only to encounter cold wind again as the trail climbs out of the gorge.

Portions of this section run through a narrow corridor alongside hunting preserves. Signs noting the hunting preserve boundaries are posted on trees along the way. Be aware of these boundaries during hunting season and wear blaze orange as an extra safety precaution. Under no circumstances should the hiker trespass into the preserves.

Camping: There is no authorized campsite on this section as of December 1, 2020. A campsite in the vicinity of Basin Creek near mile 2.3 is planned for in the future.

Water: Water is reliable from North Fork Basin Creek and Long Branch, however, it must be treated or filtered. It’s best to bring your own drinking water.

Trailhead Parking

Black Mountain Trailhead: From I 40 Exit 329, take Bat Town Rd to the Cumberland Trail State Park sign at the intersection of three roads. Turn sharp left and proceed 3 miles up the narrow and steep paved Black Mountain Road to the paved trail head parking area on the right in front of the cell tower. There is ample room for several vehicles to park. Do not block the entrance to the cell tower area. Take the paved connector trail on the west side of the parking area for 500 feet to its connection with the Cumberland Trail. Look slightly uphill to the right to see the kiosk. All measurements in this guide are taken from the trailhead kiosk.

Alternately, from the parking area, there is a short path straight downhill to the trail. If you take this shortcut, turn left on the trail to begin (end) your hike at .1 (6.6) mile.

US Hwy 70 at Ozone Falls Trailhead: From the West, take I 40 Exit 329 to US 70. Take US 70 East to the Ozone Falls SNA parking area on the right beside US 70. There is a sign as you approach stating “Ozone Falls SNA 1500 feet”. From the East, take I 40 Exit 338 onto Westel Road. Follow Westel Rd. south to US 70. Turn right onto US 70 to Ozone Falls SNA parking. There is also a sign from this approach stating “Ozone Falls SNA 1500 feet”. There is parking room for 6 or 8 vehicles right beside US 70. There is unofficial parking across the highway near the railroad trestle. Use caution crossing this busy highway.

The kiosk is immediately in front of the parking area. From there, take the path to the right that parallels US 70 for about 200 feet, then begin the descent into the gorge at the bottom of the falls.

Overview: This section guide is written in the direction of trail north. Parenthetical mileages and turns are in the direction of trail south. In a few places, specific Northbound and Southbound directions are given for clarity. The mileages for this section guide are measured from the trailhead kiosk just west of the parking area on Black Mountain. The entire section can be hiked in a single day of about 4 to 6 hours with a break for lunch and depending on stoppages along the way. Even though the hiker is making an overall descent of 1,323 ft from Black Mountain to Ozone Falls, this is a strenuous hike of 6.7 miles and the hike south bound is even more strenuous. The difficulties are the steep descents and climbs over short distances, principally the ones into and out of The Basin, Long Branch and Falls Creek gorges. Even so, the section is rewarding with a presentation of beautiful rock bluffs, deciduous forest and clear streams. In places the trail tread is directly over sandstone cap rock pushed up by continental drift roughly 300 million years ago. The trail winds, dips and rises through lovely deciduous forest. In Winter one can see the terrain plainly through the trees and into the distance. An area of land clear cut of timber in 2020 can be seen on the right (left) between about mile 1.8 and 4.3. In spring time from mid April to mid May wildflowers bloom in abundance. During the last week of April until mid May look for pink moccasin flower blooming in profusion on Black Mountain and huge gardens of cinnamon and glade ferns beside the trail coming off Black Mountain.

The northbound hiker is rewarded by the sight of Ozone falls at the terminus to this section. It is a beautiful 110 ft waterfall into a plunge pool with an enormous amphitheater. The site was used by Disney Inc. to film portions of the 2016 live action movie Jungle Book. The climb from the plunge pool level to the trail terminus at the kiosk on US 70 is daunting. As you ascend (descend), marvel at the work the Cumberland Trails Conference put into creating the stone steps in 2020.

The waterfall was known as McNair Falls throughout the 19th century after a local miller who operated a grist mill at the waterfall in the 1860s. In 1896, the community of Mammy, which had grown up around the Haley tavern, changed its name to Ozone, and the name was subsequently applied to the waterfall. The name was probably adopted to reflect the high quality of air in the community, which was claimed to have been enhanced by the waterfall’s mists.
The Ozone Falls State Natural Area was established in 1973, and originally consisted of 14 acres. In 1996, it was expanded to 43 acres.
