Saeng Chan Waterfall, also known as "Namtok Long Ru" (literally "waterfall through the hole"), is located in Pha Taem National Park, Khong Chiam District, Ubon Ratchathani. It's one of Thailand's most unique natural wonders, often referred to as an "Unseen Thailand" attraction. What makes this waterfall extraordinary is that the water doesn't just fall off a cliff — instead, it cascades through a perfectly round hole in a sandstone rock ceiling, formed over thousands of years by natural erosion.

The fall is about 20 meters high and surrounded by lush vegetation and rock formations. It offers a cool, refreshing atmosphere ideal for short treks, picnics, and especially photography. The best time to visit is during the rainy season (July to early January), when the water volume is sufficient and creates the most impressive flow.

To reach the waterfall, visitors walk along a relatively short 1 km trail through a natural forest. The path is not too steep but can be slippery during the rainy season, so proper hiking or grip-soled shoes are highly recommended. For those who enjoy nature-based activities, camping is available nearby, with basic facilities provided by the national park.

Saeng Chan Waterfall is popular among both local and international tourists, particularly nature photographers. When sunlight or moonlight shines through the hole and hits the falling water, it creates surreal, magical photo opportunities. It has earned its reputation as the only "hole-fall" of its kind in Thailand, making it a must-visit destination in Ubon Ratchathani.

However, the pool at the base of the waterfall is not suitable for swimming due to strong currents and rocky terrain. Visitors should take extra care, especially those with young children. It's also advisable to bring drinking water and personal items, as there are no shops or food stalls nearby.
