Water Festival timing and Siem Reap: what it actually means for your trip
I got a handful of messages before a late-November trip asking if I’d be at the boat races, and I had to explain each time that no, I wouldn’t — because the boat races aren’t in Siem Reap. This is the most common mix-up I see around Bon Om Touk, and it’s worth sorting out before it reshapes a trip around an event that’s happening 300 kilometers away.
Where the festival actually happens
Bon Om Touk, the Cambodian Water Festival, is centered on the Tonlé Sap and Mekong rivers in Phnom Penh, where the famous dragon-boat races, illuminated floats, and fireworks take place over three days — 23-25 November 2026. It marks the reversal of the Tonlé Sap’s flow, a genuinely unusual hydrological event tied to the lake’s seasonal expansion and contraction, and Phnom Penh is where the crowds, the river-front races, and the national coverage concentrate. Siem Reap is not a festival site in the same sense — there’s no equivalent boat-race spectacle on the smaller waterways here.
What actually happens in Siem Reap during Water Festival week
Siem Reap doesn’t sit this one out entirely. Local and smaller-scale festivities happen around the Siem Reap River and pagodas in town, and there’s a general public-holiday atmosphere — some shops close, Cambodian families travel for the long weekend, and hotels see a bump in domestic bookings. But if you’re picturing the scale of what gets broadcast from Phnom Penh, adjust expectations: this is a quieter, secondary version of the national event, not a smaller replica of it.
Should you add Phnom Penh for the festival?
If the race spectacle itself is the draw, yes — it’s worth the trip, and late November is otherwise a strong time to visit Phnom Penh anyway, with the dry season resuming and temperatures easing into the 25-30°C range. The honest Siem Reap to Phnom Penh guide has the transport options (roughly 5-6 hours by road, or a short flight), and my Phnom Penh add-on notes cover how to slot a couple of days there into a broader Cambodia trip. Expect Phnom Penh accommodation to book up and price up around the festival dates specifically, so reserve ahead if this is the plan.
Check private transfer options if you’re adding Phnom PenhWhy late November is still a good Siem Reap window regardless
Independent of the festival, late November lands right at the start of dry season resuming — cooling temperatures, rain tapering off, and the landscape still holding some of the rainy season’s green before the dust of peak dry season sets in. It’s a shoulder-to-peak transition, meaning prices and crowds are rising from their low-season lows but haven’t hit the January peak yet. If you’re not chasing the festival at all, this is simply a solid time to be at Angkor: see the best time to visit guide for the full month-by-month picture.
What I’d actually plan
If Water Festival matters to your trip, base yourself in Phnom Penh for those three specific days and treat Siem Reap as the temple-focused half of the itinerary on either side of it — not the other way around. Trying to “catch some of the festival” from Siem Reap and drive down for a single day of races is a long round trip for a partial experience. A cleaner structure is Siem Reap first (temples, floating villages, town), then Phnom Penh timed to land on the festival dates, then fly home from there rather than backtracking. If your dates don’t line up with the festival at all, don’t let it drive the itinerary — Siem Reap in late November stands on its own.
What to know if you’re in Siem Reap and not going to Phnom Penh
Expect some restaurants and small shops around town to close or shorten hours for a day or two, particularly ones with staff who travel to see the races on TV with family or head to Phnom Penh themselves. Angkor Archaeological Park operates normally. If you want a local echo of the festival mood without the trip south, the riverside area along the Siem Reap River in town sometimes has small gatherings and food stalls in the evenings during the holiday — worth a walk, not worth restructuring a day around.
Frequently asked questions about Water Festival and Siem Reap

No — the main dragon-boat races and fireworks happen on the rivers in Phnom Penh. Siem Reap has a quieter, local version of the holiday atmosphere without the race spectacle.
What are the 2026 Water Festival dates?
Bon Om Touk runs 23-25 November 2026, based in Phnom Penh.
Is it worth adding Phnom Penh to a Siem Reap trip for the festival?
If watching the races is a priority, yes, and late November is a reasonable time to visit Phnom Penh regardless. Book accommodation early, since the festival dates drive a genuine local demand spike.
Does Angkor Archaeological Park close for Water Festival?
No, the park operates on its normal schedule during the festival period.
