Phaya Thaen Public Park is located in the center of Yasothon city along the Lam Thuan River. It covers an area of over 100 rai and has been developed as both a public park and a cultural learning center of Isan. The concept is based on the legend of “Phaya Thaen,” the god of rain, and “Phaya Khan Kak,” a folk tale closely linked to the origin of the famous Bun Bung Fai (Rocket Festival) in Yasothon Province.Inside the area, the highlight is the Phaya Khan Kak Museum, a giant toad-shaped architectural landmark of the city. The building has multiple floors and is designed with symbolic meanings related to local beliefs. Its exhibitions cover the legend of Phaya Khan Kak, the story of Phaya Thaen, the Bun Bung Fai tradition, as well as the lifestyle and culture of the Isan people across different eras in detail.

Nearby is the Naga Museum zone, designed as a large Naga-shaped building representing nature, water, and the abundance of the Mekong River basin. Inside, it features contemporary art exhibitions and cultural narratives that blend religion and local beliefs, making it not only a tourist attraction but also an important cultural learning space.The surrounding area is a large public park with activity lawns, jogging paths, and cycling routes surrounded by a peaceful riverside atmosphere. It is suitable for relaxation for both locals and tourists and is also used as a major venue for provincial events, especially the Yasothon Bun Bung Fai Festival held every May.Overall, Phaya Thaen Public Park is a landmark that clearly reflects the identity of Yasothon, combining nature, art, architecture, and local culture in one place. The best time to visit is in the late afternoon when the weather is cool and the sunlight enhances the beauty of the toad and Naga buildings, making it perfect for photography.
