Tough hike! Section from Detweiler to Greenwood is pretty with good climb and descent. Leaving Greenwood Furnace is easy climb on old road, and then small loose rock till the Little View. Tough walking! Little View to Frew Road turnaround much nicer with lots of rock walks - thanks trail maintainers! Section from Frew road to 655 very nice with lots of big rocks in the first 3 miles before the state game lands parking. Section after this a nice walk in the woods.
