Bon Om Touk (Cambodian Water Festival): Dates, Tickets & Venue (Phnom Penh)

What actually happens over the three days

Bon Om Touk marks the moment the Tonlé Sap River reverses course, flowing back toward the Mekong after the wet season. Phnom Penh’s riverfront, the stretch facing the Royal Palace and Wat Phnom side of the Tonlé Sap and Mekong confluence, becomes the stage.

Daytime is dragon boat racing: narrow wooden longboats, paddled by teams of dozens, sprint the river in heats over all three days. Crews come from provinces across Cambodia, so the racing has a genuine national-competition feel, not a staged show.

After sunset the mood shifts. Illuminated boats, rigged with lights in the shape of naga serpents and other national symbols, drift past the crowds. Fireworks and moon-worship ceremonies close out each night, tied to the lunar calendar that fixes the festival’s dates each year.

Where to stand along the riverfront

The riverside promenade between the Royal Palace and Wat Phnom gives the clearest sightlines to both the race course and the evening boat processions. This strip is public space, no gate, no ticket.

Crowds are dense here for good reason: this is where Cambodian families from across the country come to watch, so treat it as a shared local event rather than a tourist show. Expect the promenade to fill early on the final evening, when fireworks close the festival.

Confirm before you go

Dates, exact race schedules and any road closures around the riverfront are set by Cambodian authorities and can shift the finer details year to year. Confirm timing and tickets on the official site before finalizing plans, since street closures around the palace and riverfront reroute traffic for the full three days.

Phnom Penh hotels near the riverfront (Sisowath Quay area) fill up for this weekend specifically because of the festival, so book that neighborhood early if you want to walk to the action rather than fight traffic.

Getting around a closed-off riverfront

Sisowath Quay and the surrounding streets close to vehicle traffic for the festival, so plan to arrive on foot or by moto/tuk-tuk dropped a few streets back.

• Walk in rather than try to drive to the riverfront directly
• Arrive well before dusk if you want a spot for the illuminated boat procession
• Carry cash small bills for street food stalls that set up along the promenade
• Keep valuables close; this is the densest crowd Phnom Penh sees all year
• Pick a spot near a landmark (Wat Phnom, the Royal Palace gate) so your group can regroup if separated

Locals treat the festival as a homecoming weekend, many travel back from the provinces just for it, so buses and riverside guesthouses book out fast. Vendors sell grilled and roasted foods streetside; no reservation system exists for riverfront viewing spots, it’s first-come public ground.
