Chiang Mai’s popular Mae Sa waterfall in Doi Suthep-Pui National Park has been temporarily closed for safety reasons following heavy rain yesterday that caused a flash flood to gush down from the mountain, catching several tourists off guard despite warnings from park rangers.
Park rangers noticed unusual signs in the area and immediately warned tourists enjoying themselves in the stream at the waterfall to leave quickly for their safety.
The flash flood came so suddenly that several tourists were caught off guard, with some swept away by the strong currents. They were subsequently rescued by park rangers. No one drowned, although some suffered minor cuts and bruises and received first aid from the rangers.
Several tourists were also stranded at the waterfall and were eventually rescued.
Atthaphon Charoenchansa, director-general of the Department of National Parks, Wildlife and Plant Conservation, said today that he had instructed the chiefs of all national parks across the country to strengthen safety measures during the rainy season and warn tourists about the danger of flash floods.
Regarding the Mae Sa incident, he said it was fortunate that no one was killed or seriously injured, adding that park officials should remain on full alert during the rainy season.
He said tourists should be warned in advance of the threat of flash floods when visiting waterfalls and reminded them to strictly follow the advice of park officials.
