Thousands of miles long, passing through 156 counties, with 7,062 lookout towers, the Great Wall of China is the largest cultural relic humans have ever built. It snakes through China ever so majestically, around undulating hills and through a vast countryside, stretching from Shanhaiguan in the east to Lop Lake in the west. Wall construction began more than 2,000 years ago in an attempt to keep out the tribes from the north. The most colorful (and least costly) times to go are spring and autumn — pink cherry blossoms blanket the landscape outside of Beijing in late-March, and in mid-October red leaves abound near Badaling National Forest Park.
