Today you’ll hike from Panlongshan along the Gubeikou section of the wall to Zhuanduokou Tower in Jinshanling. This part of the wall preserves its original history, dating back to the Ming Dynasty, when it was expanded and reinforced to defend China’s northern borders. Along the way, you’ll pass many watchtowers, including the three-level 24 Window Tower. Parts of the trail are steep and uneven and at times, you’ll leave the wall to walk along country paths through villages and farmland. As you go, take in the scenic views of mountains in the distance. Tonight, you’ll stay in Jinshanling Village.
