This is an out and back singletrack, well maintained trail. Out and back is about 10 miles. There is a big climb (or downhill) at the Charlton trailhead, but otherwise there is probably an equal amount of climbing and downhill from both directions. There is a water spout on the road halfway (the locals get their drinking water there...I saw them). Not too technical, except in a few places. Near the Crystal Springs trailhead there are a few sections that overlap with 4-wheeler trails. The trail is well packed, the long slow climbs are what get you, but you're rewarded with nice long downhill sections after. The only hike-a-bike may be at the big climb/downhill at the Charlton trailhead, but it is steep, so not that long.
