This is a nice singletrack loop with a mixture of rocks and roots and a couple roll-overs to make it challenging on the descent. You'll have to pay it back on the way back up as there is a short, steep section to hike-a-bike.
The trail starts off the Air Line State Park Trail
and angles down toward the Salmon River before circling back. There are several options when you get down to the low-point to continue toward Route 16 and to the river.
