This geopark is located in northeastern Yanqing County in Beijing. It became a national geopark in 2002 because of its important petrified wood fossils. The petrified wood is located in the Upper Jurassic Tuchengzi Formation, which is approximately 140 million years old. A total of 57 pieces have been discovered. They have clear and hard textures, and growth rings are clearly visible. The wood is 0.60–1.50 m in diameter with a maximum diameter of 2.50 m. They fossils are mostly perpendicular to the ground with heights of 0.40–0.50 m to a maximum of 1 m above the ground. In 2011, dinosaur footprints from the Jurassic Period were also discovered. Yanqing is the only location in Beijing where dinosaur fossils have been found. The park also contains cultural attractions such as the Yan Great Wall, Gujia Fortress, and Chaoyang Temple.
