This trail combo is usually either hiked or mountain biked as it is almost 13 miles one way. We usually have a vehicle on both ends of the trail and ride it from south to north. Take Smullen Road off of Hwy 35 and look for the sign that takes you to the trailhead parking lot. Drop one vehicle here. Return to Hwy 35 and go south (past the "S" curves and turn left on Forest Road 44. The trailhead (#688) is about 3.5 miles up on the left hand side. About nine miles north, you will see the turn off for the Oak Ridge Trail. Be warned: this is a fairly steep downhill trail. The top part is in the trees with switchbacks, but the middle part is the gnarly nasty part. If you fall, you will hurt. The last third of the Oak Ridge trail is back in the trees with a few switchbacks. Be careful of poison oak and ticks on this trail.
