Great Wall of China, China

Emperor Qin Shi Huang ordered the construction of the Great Wall in 221 B.C. to protect China’s first feudal empire from the Huns to the north. Eventually more than 5,500 miles long from east to west, a section built after the 14th century can be seen near Beijing. Skip the restored and crowded section at Badaling and join a tour to Jinshanling or Jiankou to hike between towers and turrets, the ever-snaking wall in view, and imagine the clatter of chariot hooves beneath your feet. #nationalpark
