Thee Lor Su Waterfall
Thee Lor Su Waterfall is the biggest and the most beautiful waterfall in Thailand, also considered the sixth biggest waterfall in the world. The waterfall located in the Umphang Wildlife Sanctuary, a UNESCO World Heritage site, which links with the Thung Yai Naresuan and Huay Kha Kaeng Reserves, as well as Khlong Lan and Mae Wong National Parks. Together, they form Thailand’s largest wildlife haven and Southeast Asia’s top virgin forest. The water streams along limestone cliffs at the height of 200-300 meters down to cascading tiers which are surrounded by intact natural forests. All around the area behind the waterfall worth exploring, there’s a cave and several levels of pools for swimming but we couldn’t swim, too cold in December. I think the waterfall is the most beautiful at the end of rainy, start the cold season of Thailand (Nov-Dec) and that time you will found a lot of Thai visitors, it’s very popular destination in this time of the year. Many visitors usually buy package tour of resorts in Umphang.






Thee Lor Su Waterfall is one main reason people travel to Umphang. It is the largest waterfallof Thailand, containing many smaller drops combined together for a magnificent view. Its height is about 200 meters and total width is about 400 meters. It is most beautiful during rainy season from June to November because of the larger water flow. However during this period, the road access to the waterfall is closed for safety reason and some hiking is required. The peak season for tourism is in December and January where the water level is still high and the road to waterfall (25 km) is open for public. Only cars with four wheel drive can pass this steep and slippery road. An alternative way to reach the waterfall is by whitewater rafting downstream along the calm section of Maeklong River and then continue journey either on foot or by car for another about 12 km. Travelling this way, two waterfalls dropping into Maeklong River will be seen: Thee Lor Jo Waterfall, or Sai Rung Waterfall. The name Thee Lor Su, in Karen language, means giant waterfall or black waterfall.
