Hiking from Rocky Bottom up to Sassafras and back down is what we did. Its only about a 5-6 mile round trip hike if I remember correctly. Its not all that scenic, but a nice walk on gradual grade. There are not many options to approach Sassafras, either from the Foothills from the West or from the East. The Foothills Trail is a wonderful trail though...and would recommend to anyone. We've actually thru-hiked it 3 times.
