The Khone Phapheng Falls in Si Phan Don is said to be the widest falls in South East Asia
The Khone Phapheng Falls in Si Phan Don, close to the Cambodian border, is said to be the widest falls in South East Asia. Khone Phapheng is pure, unrestrained aggression, as millions of litres of water crash over the rocks and into Cambodia every second. This is a spectacular sight, particularly when the Mekong is at full flood, and is one of the most-visited sites in Laos. Part of the attraction is the spiritual significance the falls hold for both Lao and Thais, who believe Khone Phapheng was a natural protector that traps the evil spirits.
Due to the strong flow of water, rocks and natural obstacles is part of the Mekong River is grade, although the French for years tried unsuccessfully to enable a route to the sea of China.
The falls are included in many tour itineraries out of Don Det, including the popular kayaking and dolphin tours.
