It's a very beautiful waterfall. Water is splashing into the air from the great rock table. There is a huge opened cave created by the great rock table, so you can actually view the inside of the fall. At June, there are many hydrangea blooming. Be careful, after heavy rain, falling rocks sometimes happen.
