This trail is located in Hamilton County's Enterprise South Nature Park in Chattanooga, TN, near the new Volkswagen plant. It is easily accessed from the ADA trailhead on the Still Hollow Loop Road (the third parking area after the fork with the Poe Run Road) along with the Black Forest
Mountain Bike Trail. Ride down the paved ADA Trail, and you'll find the start of the TNT Mountain Bike Trail on the right. The trail is ridden counter-clockwise; keep right at the fork just as you enter the trail.
The main trail has nothing technical, but it will still wear you out. Even though it has a smooth natural surface with well-draining soil, there are a lot of climbs and descents to match. The trail winds along a ridge through a dense pine and hardwood forest up and down so many times you begin to lose track of how many climbs and downhills you've done. Don't "explode", though!
There is a bail out point about a third of the way down the trail which provides an exit to the Harrison Branch Road (a paved bike trail) and the Log Rhythm
Mountain Bike Trail. The trail continues left at the fork with the connector and generally gives you more of what you've already experienced: fun! Along the way back on the loop, you'll encounter a pump track on your right with a bunch of red clay berms and a short "rock garden" (don't worry, it's nothing intimidating) before you return to the ADA Trail.
The TNT Mountain Bike Trail can be done in a stacked loop with the Black Forest
Mountain Bike Trail and the Log Rhythm
Mountain Bike Trail for a roughly 9-mile ride.
The Enterprise South Nature Park is situated on 2,800 wooded acres that were previously a part of the Volunteer Army Ammunition Plant property. The propertys heritage has been preserved in the concrete magazines used to store explosives during the days TNT was manufactured on the property. The Park offers miles of walking paths, bicycle paths and off-road biking trails. There are areas for picnics and a small lake that attracts deer, turkeys and other park inhabitants giving visitors an opportunity to view the animals in a natural setting.
