Wang Bua Daeng is situated within the "Nong Bo" marshland, a vast public wetland spanning over 2,000 rai (approximately 800 acres) across the Pa Kho and Wiang Khuk subdistricts in Mueang Nong Khai District. The most densely populated area of these aquatic blooms is concentrated near Ban Phai Si Thong and Ban Pa Kho. The name "Wang Bua Daeng," which translates to "The Palace of Red Lotuses," originates from the natural basin-like geography of the lake where thousands of Red Water Lilies (Nymphaea pubescens) spontaneously bloom in a vibrant shade of deep pink, almost crimson, during the cool season. This location stands out as a high-biodiversity sanctuary, serving as a vital habitat for various species of local and migratory waterbirds, such as Lesser Whistling Ducks, Egrets, and Common Moorhens. It also functions as a primary breeding ground for freshwater fish, sustaining the traditional fishing livelihoods of the surrounding villagers.

The tourism management at Wang Bua Daeng is a premier example of a robust "Community-Based Enterprise." Local residents of Ban Phai Si Thong have organized a dedicated rowing boat group to foster sustainable local income. A defining characteristic of Wang Bua Daeng is the exclusive use of "manually rowed wooden boats" for sightseeing. This eco-friendly approach is strictly maintained to minimize noise pollution and prevent oil residue from harming the lilies' delicate root systems or disturbing the avian population. Visitors are treated to an exceptionally tranquil experience, hearing only the gentle rhythmic splashes of oars and the distant calls of birds. Throughout the journey, the local rowers act as authentic guides, sharing folklore about Nong Bo, teaching visitors how to identify the best blooms, and demonstrating traditional lily harvesting techniques—a practice that beautifully illustrates the harmonious and sustainable relationship between the people of the Mekong Basin and their natural environment.

• From Nong Khai town, take Highway 242 (the road along the Mekong River) towards Pakho Subdistrict. The distance is approximately 16-20 kilometers. There are signs along the way indicating the route to the boat departure point at Ban Phai Si Thong or Ban Pakho.
