Tongling Grand Canyon is located at the bottom of Tongling Grand Canyon scenic area. When you enter the Grand Canyon, you will see the turbulent River plunged into Tiankeng a waterfall of more than 160 meters high hanging upside down Qianchuan. The sound of the waterfall in the canyon is deafening and spectacular. When the waterfall meets the underground river about 800 meters long and enters a deep pool under the waterfall, it disappears silently in the underground river. This is a beautiful scenic spot worth seeing.
