The spring water is naturally filtered through limestone layers, which provides its distinctive clear, turquoise hue.
The site acts as the primary headwater for the local irrigation canal system serving nearby agriculture.
Unlike many regional springs that become murky during monsoon season, this site remains clear due to the deep-seated nature of its limestone aquifer.
Ban Tha Chang Spring, locally known as Nam Phut, features a series of tiered, crystal-clear turquoise pools fed by a natural underground limestone spring. The water maintains a constant cool temperature year-round due to its subterranean source. The site is characterized by lush vegetation and large shade trees surrounding the water. Stone steps and wooden walkways facilitate access to the pools. The water flows into a canal system that eventually feeds into the Lam Takhong River. The park area includes grassy banks suitable for picnics.
