A popular side trip from the classic Three Gorges Yangtze cruise, the Lesser Three Gorges extend along the Daning River, a Yangtze tributary that meets the main river at Wu Gorge. Also known as the Little Three Gorges, Small Three Gorges, or Xiao Sanxia, the three are: Dragon Gate Gorge (Longmen Xia), Emerald Gorge (Dicui Xia), and Misty Gorge (Bawu Xia).
