The Great Wall is a must for any first-time traveler to Beijing. However, it is also the most touristy thing you can do, meaning there are throngs of people around to unintentionally (or intentionally) photobomb your memories. Jinshanling is a great section of the wall to explore for those that want to get away from the wall and see a bit more of the original, unrestored wall.
Located about 125km outside of the Beijing city center, Jinshanling is a beautiful part of the wall that is much less touristy than the very popular Badaling section. Transport can be difficult so going with a small tour is recommended. The hike up an around the wall is around 10km long. There is a cable car that cam be paid for to go up or down the wall too.
