Yanjin Old Yellow River Forest Park was established in 1993 on the basis of Yanjin Forest Farm, covering a managed area of 63,000 mu. It boasts extensive wetlands and sand dunes, with a forest coverage rate of nearly 90%. Home to the largest black locust forest in northern Henan, it was designated a provincial-level forest park in 1995.

The shallow shoals along the old course of the Yellow River attract dozens of rare bird species such as whooper swans to spend the winter here every year. In 1995, this area was officially designated the National Nature Reserve for Wetland Birds along the Old Yellow River in Northern Henan.

The park also preserves a wealth of cultural and historical sites, including Wuqi City, a river ferry stronghold guarded by Wu Qi, a renowned general of the Warring States Period, as well as the relics of Jiji, where Jiang Ziya once took refuge and made a living selling pan-fried dumplings.
