The smooth monoliths of the riverbed of the Namesawa Valley are natural art polished by the clear streams of Amagi. While looking at the traces of lava flow, debris flow formations and wasabi fields, we will walk to Taro Sugi (Cedar). On the way back, we will stop at a waterfall in the shape of a dragon. What part of the waterfall is called the "dragon"? Please enjoy the puzzle-solving time.
