The Baotou Resonant Sand Gorge, located 50km south of the city proper, is more a place of natural beauty than of historical importance. The Gorge is a part of the vast Gobi desert that starts just to the south of Baotou and that spreads over Inner Mongolia, Gansu, Qinghai, Ningxia and Xinjiang provinces. The sand gorge is a not easily accessible area of numerous sand dunes that rise up to levels of over 90 meters. It receives its name from the echoing Shhhh that the sand makes as you step on its surface. Visitors here can try camel rides, can parasail, can slide the dunes or simply build sand castles.
