Sopheak Mit Waterfall, commonly known as Preah Nimith Waterfall or Lbak Khaon, is a large and spectacular natural attraction located along the Upper Mekong River in northern Cambodia. It forms a natural boundary between Preah Vihear Province and Stung Treng Province in Cambodia, bordering Champasak Province, Laos.
The upper section of Sopheap Mit Rapids is located in Preah Vihear Province, in Kampong Preah Ind village, Kampong Sralau Pir Commune, Chhaeb District. Local people and older textbooks have commonly referred to it as Lbak Khaon or Preah Nimith Waterfall.
The lower section of Sopheak Mit Waterfall is located in Stung Treng Province, near Preah Romkel Commune, Thala Barivat District. The name Sopheak Mit Waterfall, or Lbak Khaon, has been passed down through generations and is also found in older songs and textbooks.
Sopheak Mit Waterfall is one of the world’s most remarkable waterfalls; this spectacular natural wonder ranks fourth globally by volume and is recognized as the widest waterfall in the world, spanning nearly 10 kilometers. It is also the largest waterfall in Southeast Asia. Here, the Mekong River dramatically drops 21 meters along the Laos–Cambodia border. Despite holding several impressive records, the waterfall remains a hidden gem in Cambodia due to its isolated location.
In the rainy season, the river carries a tremendous volume of water, creating powerful, turbulent rapids with spectacular waves and foaming water.
And in the dry season (approximately November to May) is generally the best time for recreation, as the water is clearer and calmer. Visitors can enjoy the water or relax in small shelters built among the rocky areas.
Preah Romkel Tourism Community is located near the Sopheak Mit Waterfall. This community offers visitors opportunities to take boat trips through flooded forests, go kayaking, and camp in the surrounding natural environment.
Today, improved road infrastructure has made the area much more accessible than it was in the past. From Stung Treng City, the site is approximately 60 kilometers away, with the journey following National Road 9 before continuing onto local roads. From Preah Vihear Provincial Town, the site is about 170 kilometers away, making it a relatively convenient destination for visitors traveling from either location.
