The Great Wall China

Fiction: The Great Wall of China can be seen from outer space (with the naked eye). Fact: it is pretty fantastic to view up close and personal. It sweeps through approximately 4,000 miles of northern China, and different sections guarantee different tourist experiences: The jungly sections of Simatai and Jinshanling are good for hiking; the arresting and gorgeous Mutianyu stretch is good for snapping photos; and the crowded Badaling portion is good for convenience (it's only an hour away from exciting Beijing). Plan your trip for anytime (just imagine the contrast of the Great Wall with the white snow of winter, the red leaves of fall and the green grass of spring and summer), but do try to bypass the hordes of tourists that visit on the weekends year-round.
