Doi Suthep-Pui National Park officials rescued tourists after a sudden flash flood at Mae Sa Waterfall on August 15, 2026.
On August 15, 2026, a sudden flash flood occurred at Mae Sa Waterfall within the Doi Suthep-Pui National Park in Chiang Mai’s Mae Rim district. According to Khaosod Online Thailand, park officials stationed at the waterfall observed natural warning signs and immediately instructed visitors to evacuate the water and the surrounding area.
Despite these efforts, the rapid onset of the floodwaters prevented some visitors from exiting the area in time. Park staff conducted an emergency rescue operation, successfully moving all stranded individuals to safety. While most tourists sustained only minor abrasions, one individual who was swept by the current reported dizziness and pain. This person was transported to a hospital via the Mae Rim Subdistrict Municipality for further medical evaluation.
For travelers and residents, this incident highlights the inherent risks of visiting waterfalls during Thailand’s rainy season. Park authorities are urging visitors to check weather forecasts and local conditions before planning trips and to strictly adhere to all safety warnings provided by staff. While the immediate situation has been resolved, the park continues to emphasize the importance of assessing natural risks in mountainous areas during periods of heavy rainfall. It remains to be confirmed if any specific trail closures will be implemented at the park following this event.
