Doi Suthep-Pui National Park Closes Mae Sa and Tat Mok Waterfalls Due to Flash Floods

On September 10, 2026, Matichon Online reported that officials at Doi Suthep-Pui National Park have ordered the immediate closure of the Mae Sa and Tat Mok waterfalls. This decision follows intense, sustained rainfall in the region, which triggered flash floods at both sites.

Park management implemented the closure as a precautionary measure to ensure public safety and prevent potential accidents, citing concerns over the unpredictable nature of the water flow. The sudden surge of water from the mountains has made these areas hazardous for visitors.

For travelers and residents in Chiang Mai, this means that access to these specific natural attractions is currently restricted. Those planning trips to the area should adjust their itineraries accordingly and monitor official park announcements for updates on when the sites might be deemed safe for reopening. As of now, there is no confirmed timeline for when the waterfalls will be accessible again, as authorities continue to monitor the environmental conditions and the stability of the terrain following the heavy rains. Visitors are advised to avoid these locations until official clearance is provided by the national park administration.
