Bon Om Touk

Held over three days each late October or November, Bon Om Touk, the Cambodian Water and Moon Festival, celebrates a genuinely unique natural phenomenon: the reversal of the Tonlé Sap River's flow, marking the end of the monsoon season. The festival draws several million people to Phnom Penh's Sisowath Quay riverfront each year, making it one of the largest annual gatherings anywhere in Cambodia.

Dragon boat races form the festival's central spectacle, with longboats from across the country's provinces competing along the riverfront in dramatic, tightly contested races, followed by fireworks and evening concerts that keep the riverside alive well into the night. Amok trey, Cambodia's national dish of fragrant coconut fish curry, holds a particular significance during the Water Festival specifically, traditionally served as a way of thanking the Mekong River system for its abundant fish and fertile land — a direct culinary expression of the festival's deeper purpose.

Given Bon Om Touk shares roots with similar water festivals across the region, including Thailand's Loy Krathong and Myanmar's Tazaungdaing, the celebration offers a genuinely significant window into how closely Southeast Asia's river cultures remain tied to the rhythms of their waterways, even as Cambodia's version carries its own distinct royal ceremonial elements.
