You can climb the Jiaoshan part along the Great Wall until you meet the Tower. This is shown in the first photo. Then once you climb vertically the Tower, you have to deviate to some paths away from the Great Wall. Unless you have some ropes or special climbing equipment, it is not possible to continue on the great wall. These paths are OK to begin with but then you will pass a temple on your left. The third photo is on top of the Tower.
The temple is shown on the fourth photo. After the temple, the climb becomes steep and there are no footpaths as I remember.
For me, it was really difficult. Yes the photo is taken on top of Jiaoshan.
To continue east, it seems hopeless !!! You have to descend down a valley and then climb up again ! I abandoned the plan to continue due to the steepness and man, it was really steep !!!!
