This large park around a lake and its famous large yellow duck is pleasant and mainly frequented in the evening when it is less hot and many locals come to relax or do a little exercise. It won't be your most memorable visit here but I still put it in the must visit places because it is one of the nicest places in town. The park's name commes from the city's founder's name. It has two entrances, the main entrance opposite Prajaktra Hotel and the other on Thesa Alley, where you will find many food stalls. There are also massage shops around the park.
Note that the Udon Thani Tourist Office (TAT) is located near Nong Prajak Park on the giant duck side.
