During the rainy season from August to September each year, the strong currents create a unique natural phenomenon in Thailand known as the "Shrimp Parade" at Kaeng Lamduan Waterfall. This waterfall, formed by natural rock pools, is located within the Ubon Ratchathani Wildlife Development and Conservation Station, a major tourist attraction in Ubon Ratchathani province.

The "shrimp procession" phenomenon involves hundreds of thousands of shrimp marching against the current of the Laem Duan rapids to the Khok Hin Lan Pan Roo area, before heading to the Phnom Dong Rak mountain range. This is the breeding and spawning season for the shrimp, and they must return to their birthplace at the headwaters on the mountaintop. As the strong current makes it impossible for them to swim upstream, these shrimp must walk over rocks and gradually climb higher to avoid the swiftness of the current. They climb up and down within a distance of no more than 2 meters at each point and travel from around 9 pm to 4 am the next day (in 2014, the shrimp procession occurred during the daytime). The shrimp procession mainly consists of "small shrimp" and "hairy-legged shrimp," which tend to live together in groups and inhabit the surface of the water or the edge of the bank. For those interested in visiting, it is recommended to call the officials for information before going to avoid wasting time.

- The shrimp parade is a natural phenomenon that is truly unpredictable and cannot be controlled.
- The shrimp parade can be observed from around 6:00 PM onwards, which is during the nighttime.
- The number of shrimp observed will vary depending on the weather conditions and water levels, and is not related to the time of day (although some people believe that the later it gets, the more shrimp there will be).

- During the festival, staff will be available to assist until 10:00 PM.
- Visitors arriving outside of these hours will not be permitted to enter the premises for their own safety and to avoid excessive disruption to the ecosystem.
