Cambodian Water Festival

When is the Cambodian Water Festival?

Bon Om Touk, also known as the Cambodian Water Festival, is a three day festival celebrated on the full moon in October or November.

History of the Cambodian Water Festival

The festival marks a reversal of the flow between the Mekong and Tonle Sap rivers. Due to the amount of water deposited during the rainy season, the Tonle Sap river becomes so swollen with water that it reverses the direction of its flow and flows upstream to Tonle Sap lake.

The festival marks the switching of the flow back to its normal direction, signifying the end of the rainy season. Essentially, the festival is a time to give thanks to the rivers as they provide the region with fertile farming land and plenty of fish.

The festival is focused on boat races and concerts. The roots of the boat races can be traced back to the times of the Angkorian kings who would train and evaluate the fighting skills of their water based warriors by holding competitions on the river. These trials in turn honoured the naval victories of the Khmer empire under the leadership of Jayavarman VII in the twelfth century.

How is the Cambodian Water Festival celebrated?

The festival is one of the largest and most popular in Cambodia. Almost every town and village across Cambodia takes part in the festival, but by far, the most popular place to be is Sisowath Quay in Phnom Pen where up to four million people will converge to watch the boat races.

The celebrations carry on night and day for the three days of the festival, with the river illuminated by fireworks and numerous brightly-lit boats under the full moon.

Ork Ambok

A traditional Khmer delicacy popular during Bon Om Touk is Ork Ambok​, a rice dish where rice is fried in the husk, then crushed and mixed with banana and coconut.


For the fourth time in five years, the boat races and related festivities in Phnom Penh in 2015 were cancelled due to low water levels. If this happens, the festival remains a public holiday.
