Nong Prajak Park

Nong Prajak Park is a large urban public park centered on Nong Prajak Lake in Mak Khaeng Subdistrict, Mueang Udon Thani District, Udon Thani city, northeastern Thailand. Named after Prince Prajak Silapakom, the founder of Udon Thani, it is the city's main recreational green space. The park features a scenic lake with islands, landscaped gardens, walking and cycling tracks, and monuments, serving as a popular destination for exercise, leisure and family outings.

Visitors can expect a large landscaped park surrounding a central lake with bridges connecting small islands. The park has a 3.3 km paved walking, jogging and cycling track encircling the lake, gardens with flowers and trees, playgrounds, outdoor fitness equipment, and food stalls. The lake offers pedal boats and rowboats, ducks and fish, and views of fountains and the city skyline. Areas for picnicking, photography and relaxation are available throughout the park.

The lake was originally called Nong Na Kluea and was developed as a water reservoir for Udon Thani. It was later renamed Nong Prajak in honour of Prince Prajak Silapakom, son of King Rama IV and founder of Udon Thani city in 1893. The park was developed around the reservoir as the city's principal public park and has been expanded and landscaped by the Udon Thani Municipality.

Nong Prajak Park is the main public recreational and social gathering place for residents of Udon Thani. It is used daily for exercise, family leisure, festivals and community events, and is regarded as a landmark symbol of the city associated with its founder.
