Lanzhou was once a major Silk Road staging post. The scenic spots along the Yellow River are gorgeous. Visitors can fully enjoy themselves by joining the Yellow River Scenic Route to see the symbol of Lanzhou: the Statue of Yellow River Mother and Yellow River Waterwheel Park. The newly renovated Gansu Provincial Museum and White Pagoda Park are worth visiting. The Binglingsi Grotto is another must see place in Lanzhou. There are 184 caves and niches dating from the Liang (AD502-57) to the Ming (1368-1644).
