I'm going to let the pictures speak for themselves – the Great Wall was one of the highlights of our visit to Beijing. We highly recommend doing a hike with Beijing Hikers, my sister's friend Zach often leads the hikes and he's a great guide. You can experience the Great Wall away from the tourist hordes, meet other people, and see for yourself why it's called the Great Wall!
A Surlee Voyage 
I hope someday I will get to visit the Great Wall!
