Luoyang's Wangcheng Park is a public park which can be divided into five different sections—the public garden area, a zoo, a fun park, a peony garden area and a culture section—all of which require separate admission fees. There's not a lot to attract the interest of the average traveler unless you have a particular interest in the happenings of the Zhou Dynasty (1046 - 256 BC) or China's symbolic flower, the peony, which they like to call "The King of Flowers". 

Every year for 10 days in April (15th - 25th), thousands of peony fans descend on Wangcheng Park to see their king of flowers in full bloom. When this Peony Festival is on, an admission fee of RMB 20 is charged. If you happen to visit in the off season, don't be surprised if you find artificial flowers attached to the peony plants.

The Cultural and Historical section of the park houses some interesting artifacts and stone inscriptions dating back more than a millennium BC. Short history lessons are available, unfortunately still only in Chinese. That aside, this section of the park is quite interesting.

The remaining areas of the park can safely be avoided—unless you want to take a ride on a rickety looking Ferris wheel. You might want to give the zoo a wide berth, as you'll probably just end up feeling sorry for the animals in their tiny enclosures.
