Fodor's Expert Review Singing Sand Mountain
South of Dunhuang, where the oasis gives way to desert, you'll find a gorgeous sweep of sand dunes named for the light rattling sound that the sand makes when wind blows across the surface. At 5,600 feet above sea level, the half-hour climb to the summit is difficult but worth it for the views, particularly at sunset. Nestled in the sand is Crescent Moon Lake (月牙泉, Yuèyá quán), a lovely pool that by some freak of the prevailing winds never silts up. Camels, sleds, and various flying contraptions are available at steep prices; try your bargaining skills.
