Great view (and lunch) at the Great Wall!!
The best side to visit The Great Wall is without question the Mutianyu section, by far better than Badaling, less crowded, older and just prettier. And if you top it with lunch at this new place called The Schoolhouse, you would have a terrific time! Great ambiance, great western (and chinese) food and relaxing views. (oh, and please let me say, great clean western bathrooms!!)
