mostly loose dirt and bark from trees, some rock towards the end of the trail..
Starts near camp ground and is marked, Bench Trail...follow trail over downed trees and other obsticals and when sign becomes visable on upright tree, stay to the right.....after this, there are many uphill climbs, (better for cross country bikes)....towards the end of the trail gets rocky and bumpy, and in one part there is a small ladder drop...
