Hiking (in either direction) on the restored section of the Wall here is straightforward. There's an east gate and a west gate (about 2km apart), which means you can do a round trip (90 minutes) without backtracking; from the east gate, turn right at the Wall to find the west gate, then right again once back down on the road. At the time of writing, though, the east gate was closed, so you can only get onto the Wall from the west gate. If you need it, there’s a cable car by the west-gate ticket office. If you want to find some unrestored sections, turn right when you hit the Wall and just keep going. This stretch eventually leads to Gǔběikǒu (6½ hours), although you have to leave the Wall for an hour or two in order to walk around the boundary of a small military camp.
