The Great Wall of China is the famous term used to describe a series of walls and fortifications which protected the states and empires of China from nomadic groups north of the border. The total length of the wall is about 21,196 km (13,171 miles), and today most visitors choose a section to visit depending on what they’d like to see.
The Badaling Great Wall is the most visited section and has been extensively restored. The Mutianyu section of the Great Wall of China is one of the most complete and one of the closest to the city of Beijing, being technically still within the city limits. It’s less popular than the Badaling section but can still be extremely busy. At Mutianyu you can ride the cable car up to the watchtowers, explore the length of the magnificent wall, or zip down on the exciting 1.6 km (1 mile) long speed slide.
The Simatai section is known for its steep slopes and fantastic views and is a great choice for those who want to hike a section of the wall. The Huanghuacheng Great Wall is mostly unrestored and is much less busy than other sections of the wall, and it’s also the only stretch which is close to lakes.
