Although there are many buses on the mountain, we still need to walk to the scenic spots. I just came back from Yuntai Mountain a few days ago, and I'm really tired. But maybe it has something to do with my lack of exercise. There are many distances to the Great Waterfall, Xiaozhaigou or Hongshixia. Places with good road conditions are all ready-made stairs, depending on your own physical strength.
Yuntai Mountain has a good scenery and is worth visiting. Have fun!
Also, by the way, there are many scenic spots, large and small. If you only go for one day, you can't play. Their tickets are valid for two days, and they can stay for one night if conditions permit.
All right, that's all. I hope it works for you.
