About 6 miles of trail in a "stacked loop" configuration. The main trail is the Mountain Express; other trails include Deer Run, Lower Spring Loop, and Upper Spring Loop. You'll need to backtrack a bit to ride everything in a single visit.<br />
<br />
Trails are generally rocky but the elevation changes aren't too bad (longest climbs are about 400 feet). The trail is tough to follow in some places, particularly the Mountain Express trail near the top (lots of side trails leading to the road). Some cool Rhododendron tunnels and great views in winter.
Take AL Hwy 281 to Cheaha State Park. Trailhead kiosk is located just outside the main entrance gate. $2 entry fee per person.
