The scenery is beautiful, with lush greenery and flowing blue water. The valley is characterized by its many rocks, and the water is crystal clear with frequent small waterfalls. Although the one-way A route is 6 kilometers, there are sightseeing buses at intervals, satisfying both hiking and sightseeing needs; you can choose according to your preference. At the summit is a hidden gem of dove trees, which must be incredibly beautiful when the dove trees are in bloom; I highly recommend visiting then. On the final stretch of the descent, there are bamboo rafts to the exit, allowing for frequent water activities along the entire route, and the bamboo rafting adds a lot of fun. Highly recommended! I just wonder if there's accommodation at the summit; that would be fantastic.
