THE GREAT WALL of China, stretching 5,500 miles from Shanhaiguan in the east to Lop Lake in the west, is one of the great marvels of the world.
Most tourists visit Badaling, a section near Beijing that has been heavily restored and and built up as a tourist destination.
But some adventurous tourists venture to the sections of the wall that are less travelled and unrestored. In many cases these sections are difficult to reach and crumbling.
BusinessInsider.com readers Rindge Leaphart and Nataki Goodall visited one of these sections in 2008 and shared their photos and story with us. The section they hiked, between Jinshanling and Simitai, was closed in 2010 for safety reasons, and tourists have not been allowed there since.
