I like this park a lot. It's probably the best part of Weifang county. Except for the nonsense theme park at the northern end near the entrance, it is a beautiful place. It is perfect for a cycle (the roads are in great condition) or a long walk. The route around the park is about 10km. Moreover there are exciting pathways that crisscross through the trees and bushes (it's quite a maze so be careful). Each stretch of the park has it's own character; woodland, grassland, orchard, flower garden, ancient cottage etc). I suggest a visit on weekdays in the morning or afternoon, as it can get quite crowded on weekends.
