Tat Kinnaree Waterfall is located within the boundary of Phu Langka National Park, spanning the border area between Nakhon Phanom and Bueng Kan provinces, specifically in the Bueng Khong Long District. The most striking feature of this waterfall is its unique geological structure, consisting of massive sandstone formations. These rocks have undergone millions of years of natural erosion by water and wind, resulting in smooth, curved shapes with markings that resemble eyes and mouths, making them look like a pod of dozens of dolphins leaping out of the water. These formations are part of the Phu Thok rock group, which is geologically significant to the Isan region.

The waterfall consists of four tiers, each offering different physical characteristics and aesthetic appeal. The fourth tier is considered the highlight and the most famous photography spot, as it houses the renowned "Dolphin Stones" amidst a lush, dry evergreen forest. During the rainy season, when relative humidity is high, these rocks become covered in vibrant green moss and lichen, providing a stark contrast to the reddish-brown sandstone and the white water cascading over the low rock shelves. This creates a mystical, fairytale-like scenery that is rarely seen in any other waterfall across Thailand.

Beyond its natural beauty, the Tat Kinnaree Waterfall area is integral to the local tourism routes centered on faith and folklore. Situated on the Phu Langka mountain range, local legends suggest this is a mystical realm of the Naga (great serpents) and has historically been a site for meditation by many revered forest monks. Visitors to the falls, therefore, experience more than just an extraordinary geological phenomenon; they also absorb the tranquil and sacred atmosphere of the forest. The walking trail to the waterfall has been developed for accessibility while meticulously preserving the surrounding environment's natural integrity.
