The Black Forest Mountain Bike Trail is the easiest of the four mountain bike trails at Enterprise South Nature Park in Chattanooga, TN. It is most easily accessed from the P-3 parking lot on Poe Run road about a mile straight in after passing the Visitor Center. There is a one-way 5.8 mi. vehicle only road called Still Hollow Loop that goes around the park perimeter. You can use Still Hollow Loop to access Black Forest from the P-4 parking area or the P-6 area (this also has direct access to the TNT Mountain Bike Trail and the Atlas Trail.) Parking Lot P-3 is the most popular since it has restrooms.

Leaving from the P-3 trailhead this is a directional trail, one-way depending on the day. Counter Clockwise: Monday, Wednesday, Friday & Saturday this one starts with a steady climb to get you going. Clockwise: Tuesday, Thursday and Sunday there's a climb with hairpin turn very early in the ride to get your heart rate up quick. The uphills from the main parking area in either direction make for an enjoyable descent when you are finishing it up especially in the counterclockwise M, W, F & SA direction. Up and down sections throughout, no real hard climbs, some rooty sections, no rock gardens. A number of nice fast flowy sections when ridden in either direction through mainly a hardwood forest with some pines here and there. Only one of the ammunition bunkers is on this loop, but there are over 100 in the park. Trails are multiuse but you only see occasional runners, or hikers met a leashed dog only once in the last year. Deer and turkey are common sites. February 2019 at the intersection with the TNT trailhead a Mountain Biking Skills Challenge area is nearing completion. You can access the other three trails in this system from the Black Forest Mountain Bike Trail: TNT Mountain Bike Trail and Atlas Trail directly and Log Rhythm by riding half of TNT first. Note: Log Rhythm is one way only always counterclockwise. Love this trail system ride it often.

Enterprise South Nature Park is situated on 2,800 wooded acres that were once a part of the Volunteer Army Ammunition Plant property. The property's heritage has been preserved in the concrete bunkers used to store explosives during the days TNT was manufactured on the site. The Park offers 16 mi. of multi-use mountain bike trails; 9 mi. of paved pedestrian/bicycle trails; 9 mi. of walking paths for pedestrians only; 3 Bunker historical displays; 5.9 mi. scenic overlook drive, 10 mi. of horse trails.

Great beginner trail! Only word for caution is with the leaves falling it makes it a little more difficult to see tree roots or smaller rocks on trail — 0h 38m
