Willis Knob serves as an access road to the Willis Knob horse campground in the Chattahoochee National Forest. The campground isn't far once you turn off the pavement, but the Willis Knob trail continues on for several miles. Like other trails in the area, the further you go, the more degraded the trail becomes. The trail is easy until the 6-mile mark, where 4WD and high clearance are likely required to traverse a very deep and long washout. Prior to this point, 2WD will do just fine. Also, beware of fallen trees that have been just barely cleared from the trail. These trees could easily tag the side of a vehicle if not cautious.
You can expect to see ample greenery in the warmer months and plenty of wildlife if you take it slow and quiet. You may even catch a crawfish hopping from mud hole to mud hole.
Willis Knob horse campground is available by reservation only. No other dispersed camping along the road exists.
