David Falls is located near Bokhara, Nepal. It is the dry season to enter the scenic spot. The river bed is exposed and the raging river cannot be seen. There is only a small stream under the staggered river bed. Finally, it falls into a huge underground cave and disappears. There is no effect of forming a waterfall. There are guardrails around the cave to prevent tourists from sliding into the bottom of the valley. Because it is a dry water period, there is not much water in the cave, and tourists can go down, and the inside is dark. The young Swiss man and his partner, formerly named David, had gone down to the cave to explore and died in Huangquan, so the waterfall was named David Falls, which had a warning meaning.
