Wudu district has developed a substantial olive industry over the past few decades, and the terraced hillsides of the Bailong River valley are now covered with olive groves that look startlingly out of place in northwestern China. The trees are productive and the local cold-pressed oil is increasingly sold across the country. Walking the valley roads in autumn, when the harvest is under way, gives a vivid sense of this agricultural improbability.
The Bailong River itself, which runs through Wudu, is the main artery of the valley and the landscape along its banks — combining terraced olive groves, traditional villages, and forested ridges — is the chief attraction of the district. The river is prone to flooding during the summer rainy season; most of the valley is best visited in spring or autumn.
