Chaloem Phrakiat Park is a nice public park in the city center of Udon Thani. It has a nice Chinese temple and a walking/running track that goes around the rather large lake, the track is about 2kms long, plenty of places for kids to play, there are even paddle boats you can rent.
If you are in Udon Thani this is a nice place to visit if just you want to exercise or just relax and enjoy a bit of nature in the middle of a very busy city.
