National Forest land so be aware of hunting seasons and plan accordingly.
Continue past the metal gate and descend briefly, the two-track will gain more and more backcountry flavor from this point. After the brief descent, you'll climb again slowly before again beginning to descend slowly. At a slight saddle, the trail will angle right and blue blazes (Dry Run Trail) will begin.
You'll drop more steeply from here. The first bit is relatively smooth with some interspersed rocky sections and an interesting log 'skinny'. You'll dip into the drainage and cross the creek. From this point, the trail becomes rockier and more technical. This continues to the bottom, the trail continues to parallel the creek on the righthand side. You'll come to a hard left turn marked by multiple blue blazes and flagging. This can be easy to miss if you aren't paying attention!
Take the hard left and cross the main creek. Climb a bit and you'll reach a trail intersection. Dry Run Trail ends here.
