Scenery: It's worth going to Riyue Mountain just for the scenery in picture 1. It's on the main loop and the scenery is truly unique. The rocks at the base have Tibetan characters written on them; although I can't understand them, they still feel very sacred and auspicious.
Impressions: Overall, besides picture 1, there's not much else to see. The surrounding environment is similar to picture 4.
The wind there is really strong. If you go in winter, be sure to wear a mask, hat, sunglasses, and gloves.
