The Waterwheel Expo Park in Lanzhou is a charming riverside attraction that showcases the city’s ancient irrigation heritage with its iconic giant wooden waterwheels, some dating back to the Ming Dynasty. Free to enter and set along the scenic Yellow River, the park is peaceful and beautifully landscaped with gardens, cultural displays, and a small exhibition hall explaining how the waterwheels once supported local farming. It’s an easy and worthwhile stop—especially in spring or summer—offering a blend of history, culture, and photo-worthy views, all just a short ride from Lanzhou Railway Station.
