Festival Overview
Before the first race, a long boat must be lowered into the river.
Its hull may carry the name and pride of a community far beyond Phnom Penh. Rowers settle into narrow positions, paddles rise and the boat moves only when many bodies accept the same rhythm.
Bon Om Touk, commonly known in English as the Cambodian Water Festival, is a three-day Water and Moon Festival observed across Cambodia. Its largest public celebration is traditionally held along the Phnom Penh riverfront, where boat races, illuminated vessels, fireworks and enormous crowds mark the end of the rainy season and the changing flow of the Tonlé Sap River.
During the monsoon, the rising Mekong forces water northwest through the Tonlé Sap River and into Tonlé Sap Lake, expanding one of Southeast Asia’s most important freshwater systems. When the Mekong falls, the river changes direction again and water begins draining from the lake toward Phnom Penh.
That movement shapes fishing, farming, transportation and daily life across Cambodia. Bon Om Touk turns the seasonal change into public time.
By day, racing boats bring provincial communities onto the water before the Royal Palace. At night, illuminated vessels move along the river while families observe the full moon and share ambok, rice that has been roasted and pounded flat.
In Cambodia, the river is not simply part of the landscape.
It is a calendar the country can watch move.
