The Great Wall of China is an ancient series of walls and fortifications. It's not just one of the greatest sights in the world, it's also the longest man-made structure with a length of 21.196 kilometres which stretches from China sea port of ShanHaiGuan into GanSu Province. With more than 2300 years history it's placed on The World Heritage List by UNESCO since 1987.
The wall was originally conceived by Emporer Qin Shi Huang in the third century B.C. in order to prevent incursions from nomads. Despite its long history, The Great Wall as it exists today was constructed mainly during the Ming Dynasty (1368-1644).
Chinese people don't call it "The Great Wall", they call it "Chang Cheng" which is translated as "Long City".
Everyone should visit The Great Wall at least once in their life. There are many sections of the wall you can explore. Each one of them is unique in its own way. Here are the best ones to hike:
