No, that's not an erroneous heading. You can actually bike along the Great Wall of China, one of the world's great wonders and a UNESCO World Heritage Site. The Great Wall sprawls 5,500 miles (8,851 kilometers) across China, running east to west through forests, national parks and deserts [source: Travel China Guide]. Constructed mainly of brick and stone over a 2,000-year stretch from about 476 B.C. to 1644, the portions that remain today are mostly from the Ming Dynasty (1368 to 1644) [sources: UNESCO, Selinsky]. Unfortunately, thanks to the forces of Mother Nature and destructive humans, less than 30 percent of this magnificent structure is in good condition today [source: Travel China Guide]. So if you want to bike the wall, you'd better start planning.
Dozens of companies offer tours, typically in the spring and fall. Touring outfit Cycle China offers a one-day ride for about $100 per person. After being shuttled out of Beijing and into the country, you'll pedal along a lightly-trafficked, paved road. Soon the wall will loom into view. When you reach this historic structure, you'll park your bikes and climb on top for killer views and loads of history. Total cycling distance: about 19 to 25 miles (30 to 40 kilometers) [source: Cycle China].
