Overall, there are three lines, one is from the cuckoo valley to the ridge, the right is the unopened area, you can take two steps to see the scenery, and then come back from the left ridge to the Great Wall down to the ski resort and reservoir, this length is acceptable. If you have physical strength, you can continue to go around the temple. On the way, you can see the fox fairy cave and take a car down the mountain from the temple. It is not recommended to take the third road to continue climbing that day. The third is pure climbing. The physical strength is the highest. It is best to go here on the same day. From the asphalt road to the reservoir, turn left and go up the mountain, clockwise loop. I personally went from the entrance of the scenic spot to the top of the mountain for 110 minutes, and it was not easy. The bomb shelter was not open on the way.
