Bueng Thale Ban is a large freshwater swamp nestled in the valley, flanked by the Chinese Mountains and Khao Wang Pra. The area covers approximately 125 rai and is rich in freshwater fish and abundant shells. Surrounding the swamp, you can find dense growths of "Ton Bakong," a rare aquatic plant. The national park has constructed a pavilion at the water's edge for tourists to relax, along with wooden walkways that encircle the swamp.
