Heihe Wetland Park protects a stretch of river wetland in Zhangye, with paths and boardwalks through reeds, ponds, and open water. It is a quieter counterpart to the area's famous rainbow mountains and Buddhist cave sites.
The park is best for an easy walk, birdlife, and a softer landscape within the city area. It will not replace Zhangye's headline excursions, but it rounds out a stay with accessible nature.
