The Shimen plank road is a plank road formed by ancient people who crossed the Qinling Mountains along the river valley and chiselled holes on the cliffs. It feels very steep to go along the plank road. I have to admire the hardship and wisdom of the ancients to build the plank road... It takes more than 9 o'clock in the morning. It takes half an hour to walk to the entrance of the plank road. You can also take a small train. The first half is a ladder, more tired, the second half is a draw, walked to the end of the eagle pavilion and returned, the whole trip took more than 2 hours, I feel that the scenery is general, slightly worse than the style of the Mingyue Gorge.
