- Thi Lo Su Waterfall in Tak province is scheduled to reopen to tourists on September 1, 2026, after its annual closure during the rainy season.
- To ensure public safety, authorities are upgrading routes, rehearsing safety plans, and deploying personnel with emergency rescue equipment at high-risk points.
- The reopening will adhere to sustainable tourism principles, requiring visitors to follow strict regulations, including a ban on single-use plastics and rules against disturbing wildlife.
The Department of National Parks, Wildlife and Plant Conservation is preparing to reopen Thi Lo Su Waterfall in Umphang Wildlife Sanctuary, Tak province, to tourists on Tuesday (September 1, 2026), following a rainy-season closure to allow the natural environment to recover.
Officials are upgrading routes, rehearsing safety plans and deploying personnel at high-risk points to give the public and tourists confidence throughout their journeys.
Thi Lo Su is regarded as one of Thailand’s largest and most beautiful waterfalls.
It is located in Umphang Wildlife Sanctuary, which has been recognised as a natural World Heritage site together with the Huai Kha Khaeng and Thungyai Naresuan forests.
During the rainy season each year, the department suspends overnight stays and closes some areas to visitors so that forest and wildlife ecosystems can recover naturally.
The restrictions also reduce the risk of accidents arising from natural conditions, such as flash floods and difficult access routes.
Sukee Boonsang, director of the department’s wildlife conservation division, reported that personnel from the division and Umphang Wildlife Sanctuary were in the final stages of preparations on the ground.
These covered visitor assistance, safety arrangements and emergency rescue equipment, to ensure the highest possible level of safety for everyone visiting Thi Lo Su Waterfall when it reopens on Tuesday (September 1, 2026).
The reopening will continue to follow sustainable tourism principles.
Tourists are being asked to comply strictly with the wildlife sanctuary’s regulations, including:
- Do not bring single-use plastic waste into the area.
- Do not disturb wildlife.
- Refrain from making loud noise to preserve the area’s unspoilt natural atmosphere.
“The Department of National Parks, Wildlife and Plant Conservation hopes the reopening of Thi Lo Su Waterfall will help stimulate ecotourism in Umphang district and Tak province, support local communities’ incomes and raise awareness of the need to work together to protect natural resources. Tourists planning a visit can contact Umphang Wildlife Sanctuary for information on routes, visitor measures and advance site reservations.”
