Soi Sawan Waterfall is located in Pha Taem National Park, Khong Chiam District, Ubon Ratchathani Province. It is one of the most prominent waterfalls in northeastern Thailand, with a height_ of around 20–30 meters. What makes this waterfall unique is the convergence of two streams—Huai Soi and Huai Phai—that meet atop a cliff and plunge together in a graceful fall resembling a necklace, which is where the name "Soi Sawan" (Heavenly Necklace) comes from.

The area surrounding the waterfall is cool and shaded, ideal for relaxing and swimming, particularly during the rainy and early cool seasons (October to December) when the water flows are strong and clear. Visitors can reach the falls by walking about 500–650 meters along a forested trail from the parking area.

Nearby is a 40-rai (approximately 16-acre) field of wildflowers that blooms brightly on the rocky plains. During late rainy season to early winter, various native species such as Dusita, Manee Thewa, Sroi Suwannaa, and Thip Kesorn bloom in vibrant colors, making the area a photographer’s paradise.

Basic facilities such as parking areas, rest spots, and direction signs are available. However, there are no food stalls directly at the waterfall, so visitors should bring drinking water and sun protection.
