Hiking in China along the famous Great Wall
The Great Wall of China is one of the Seven Wonders of the World. It is a staggering 5,500 miles long, and one of the few man-made structures visible from low orbit. Stretching from Shanhaiguan in the east to Lop Nur in the west, the Great Wall of China is arguably the most expansive man-made structure ever built. This means that, although hiking in China may be challenging, the rewards are spectacular, and the memory of a trip to the Great Wall will stay with you forever.
