The limestone rock formations are exposed to varying degrees depending on the Mekong's seasonal water levels.
The rapids at Kaeng Khut Khu are created by a large group of rocks that disrupt the Mekong's current, forming a natural water hazard for river navigation.
It is a popular local source for 'Kai Pan,' a dried river weed snack seasoned with sesame and garlic, which is a signature product of Chiang Khan.

Kaeng Khut Khu is a large rocky limestone formation located in the middle of the Mekong River in Chiang Khan, Loei province. The site is characterized by massive, uniquely shaped boulders that become prominently visible during the dry season when water levels recede. It serves as a natural border marker between Thailand and Laos. Visitors can access the riverbank via a paved promenade lined with vendors selling regional food and souvenirs. The area is notable for its panoramic views of the Mekong River valley and the rugged mountain terrain on the Laotian side. During the wet season, the Mekong's rising water partially submerges the rocks, significantly altering the visible landscape compared to the dry season.
