I went to Chimney Top about five weeks ago (also via the North Fork Mtn Trail) and it was divine. Spending the night there with all that open sky and my best friend was amazing. Can't wait for this Saturday when I'll be there again!
We started on the north end of the " north fork mountain trail". When you arrive at Seneca rocks, WV you can ask for directions at the visitor center. The trail starts a short drive from Seneca Rocks, WV.
