Usually if you enter the rain from the west, you will leave from Ninnon. But the rain and snow can only return the same way, and you must not take Ninnon. There are only two road conditions: one is the cliffs on the canyon, and the road is often only two feet wide. The other is the rock at the bottom of the canyon, which is the same as under the river. On foot, Ninon is really challenging. Especially if there is fear of heights, such as me. The trekking poles are not less. The whole scenery is a combination of a variety of altitudes, a variety of styles, a variety of road conditions and a variety of vegetation. For these beautiful scenery, all the hard work is worth it. There is a rest stop in the middle, which can be supplemented and rested. In short, beautiful! Really beautiful! Really worth it!
