This trail is a multiuse, sometimes rocky trail network. There are four main loops: the Gap Hollow trail, Stave Mill Falls loop, High Mountain loop, and Black Oak (I think) loop. There are loops on old fire roads, and some single track. High Mountain loop is considered the most difficult and is supposed to be unridable in places. Stave Mill Falls loop is more managable. There are washouts and other trail anomalies from 4-wheelers and horses. There are some good sections though, some very scenic.
Take HWY 7 north from Russellville @ 23 miles (?). Its on the west side. Watch for it after you enter the Ozark Nat'l Forest. Or, from Harrison take HWY 7 south. The trail camp is right off of 65, just south of Pelsor and just north of Mack's Pines, on the west side of 7
