Walnut Fork is a nice little inside the Warwoman WMA. The trail connects Sarah's Creek and Dan Gap and makes for a beautiful looping drive through the forest. The trail continues traveling west, beyond Dan Gap, as begins to slowly degrade. Gravel gives way to dirt and mud with several shallow washes and the occasional mud hole.
There are several wild campsites along the route, with only rock-lined fire pits and the occasional picnic table. Most sites are large and suitable for 2-3 vehicles. The trail dead-ends at a closed gate and a very large campsite/clearing that could host 5-6 vehicles.
Several hiking trails and one horse trail intersect with Walnut Fork, so be mindful of hikers and horses. Otherwise, enjoy the ride and the beautiful forest scenery.
