One of the oldest existing man-made structures, more than 2,000 years old and a world-travel icon that ranks alongside the pyramids of Egypt and Stonehenge — the Great Wall of China should be on ever traveller’s bucket list.
To make the most of your visit, take some advice from these do’s and don’ts. DO choose a section of the wall that’s right for you.
Most travelers visit one of these sections from their hotel base in Beijing: Juyongguan (closest to Beijing but less interesting than most other sections); Badaling (close but crowded); Mutianyu (farther away but less crowded and set among gorgeous mountains); and Jinshanling and Simatai (farther away still, but perfect for adventurers). Note: Simatai is currently closed for site improvements.
