There are two north and two observation decks. The north observation deck is directly next to the waterfall parking lot and it is very close to walking; the south observation deck needs to park in the visitor center and walk there, but it is only a 3-5 minute foot journey. The views on both sides are different, which side is better to see the wisdom of the people (personally prefers the south angle). The viewing angle of the south observation deck. Very unexpectedly, although it was rainy, I took one of the most satisfying photos of this trip. Even though the clouds are on top, the beautiful green of the mountains and rivers renders the picture into a beautiful oil painting.
