Found this interesting link a while back and have been trying to piece together how much of the original trail still exists. The northern part of trail seems fairly straight forward, as the sections from Jiajiouliao - Xiong Kong, and Wuliaojian - Ximenshan are well traveled. However, after Ximen the path south disappears. Is there a trail that follows the foothills north/south from Ximen through Hsinchu? How about the foothills further south?
Edit: The site won’t allow me to link directly to the old fort map, so you’ll have to click on E-Map at the top of the page.
