An overgrown trail by the Great Wall. Out on to the ridgeline. Views of rough Great Wall with mountains in the distance. Hiking towards a line of broken Great Wall. Got a bit off track here. Taking a break to see what's coming up next. We'd follow the long line of wall ahead. A lot of the first part of the hike was not on the Great Wall—it's not in such good shape after 400+ years of weathering. Some of the battlements remain. The wall here is mainly made of stones and rocks. Coming down a steep section. Down a dip. The rammed earth foundation of an old tower. Looking back along the wall. … and ahead. A tower on a corner offers good long views down towards Yanqing city. A closer shot. We'd continue along the wall in front. Blue skies match the blue t-shirt! We stopped here for a lunch break. Moving on again. Rough wall near the High Tower. About to leave the wall. Picnic time after the hike.
