One Day in Phnom Penh: The Order That Makes It Bearable

One day in Phnom Penh works if you do the sights in the cool and the history in the afternoon. The reverse - which is how most combined tours sell it - finishes your day at a mass grave and then asks you to enjoy the riverfront.

08:00 Royal Palace. Royal residence since 1866 and still lived in, so the apartments are shut and the Throne Hall is seen from outside. The Silver Pagoda in the same compound is floored with five thousand solid silver tiles, mostly under carpet now with a corner left exposed, and holds a Maitreya Buddha of 90 kilograms of gold set with more than 2,000 diamonds. Shoulders and knees covered, enforced at the gate, for men too. Shoes off at the pagoda.

10:00 National Museum, a hundred metres away. The best Khmer sculpture collection in the world, in a terracotta pavilion built in 1920 around an open courtyard. It closes for lunch, which is the single scheduling constraint of the day. If you have come from Siem Reap it lands hard: these are the same figures you saw weathered and headless on the temple walls, here intact and at eye level.

11:30 Wat Phnom if you have energy, a short ride north. The hill the city is named after - *phnom* - where Lady Penh is said to have found four Buddha statues in a floating koki tree around 1372. It is a working temple and the only real shade in the centre.

Give the afternoon to these two and put nothing after them.

Tuol Sleng was an ordinary secondary school until the Khmer Rouge turned it into Security Prison 21 in 1975. The classrooms still have the blackboards, the tiled floors and the iron bed frames, and room after room is filled with the photographs the regime took of every prisoner on arrival. Between 12,000 and 20,000 people were held there. Around a dozen survived.

Choeung Ek is fifteen kilometres out, where most of them were taken to be killed. The memorial stupa holds some 5,000 skulls, arranged and labelled. Take the audio guide - it is narrated in part by a survivor, it paces you around the site, and it is the difference between walking a field and understanding it.

Allow about an hour and a half at each plus the drive: half a day for the pair. Photography is prohibited inside some cell blocks and at the stupa, and the signs are clear. Neither site suits young children.

Our full guide to both covers hours, what to read first, and what the tribunal did.

Plan this before you go, because you will not want to make decisions afterwards.

Sisowath Quay at dusk is the right weight. Phnom Penh sits where the Mekong, the Tonle Sap and the Bassac meet, and the promenade is where the city walks after work - families, food carts, aerobics classes in the park. The fact that this is a loud, ordinary, functioning capital is genuinely part of what you came to understand.

An hour on the water costs very little and is the best way to see the confluence. Sunset cruises leave from the quay all evening.

Eat simply. Kuy teav, the pork-bone noodle soup the city runs on, or lok lak with a lime and Kampot pepper sauce. The food and markets guide has where.

What does not work is a rooftop bar at seven. It is not disrespect exactly - it just does not fit.

The markets. Psar Thmei's art deco dome opened in 1937 and Psar Toul Tom Poung, the Russian Market, is the one for silver and silk - but market food is a morning thing, finished by nine or ten, and your morning is spoken for.

Koh Dach, the silk island. A short ferry upstream where weavers still work handlooms under their houses and sell at the loom. It is a half-day and it is the best thing in Phnom Penh that one day cannot reach.

Oudong, the royal capital for more than 250 years until 1866, 40 kilometres north-west with hilltop stupas holding the ashes of kings. A full day.

Kampot and Kep. Three to four hours each way. Not in one day in Phnom Penh, though they are a day trip in their own right.

The honest recommendation is two nights. Our two-day itinerary gives the Khmer Rouge sites their own afternoon and the city its own morning without either being rushed.

And leave for the airport early. Phnom Penh moved to Techo International on 9 September 2025, about 20 to 24 kilometres south - a 40 to 50 minute run, more in the evening peak, and roughly double the old airport.
