Mostly two track with some singletrack along the side of the two track. Nice long climbs and fast descents of 1200' over 2.35 miles and 1355' over 2.65 miles. It is definitely worth riding in both directions (10mi or 16km as an out and back), but there are multiple options to hook up on other trails too. Ash Mountain itself is on the left side of the trail (north side) as you descend towards the river. It is about 2/3 the way down to the river.
