Phnom Penh travel guide

Royal Palace, Angkor sculpture and the Khmer Rouge story by the Mekong

In short

Cambodia's capital sits where the Tonle Sap meets the Mekong, with the Royal Palace, the National Museum and the memorials at Tuol Sleng and Choeung Ek. Come between November and February, when it is driest and least hot. Two or three days covers it. Costs are low, and the Cambodian visa is available online or on arrival.

Cambodia's capital spreads along the west bank where the Tonle Sap joins the Mekong, with the Bassac branching away to the south. Most visitors give it two or three days for the Royal Palace, the National Museum and the Khmer Rouge sites, then carry on to Siem Reap, the south coast or Vietnam.

Best time to visit Phnom Penh

Month by month, so you can pick the weather and the crowds you want.

Full weather guide
Best overall
November - February

Highs of 31 to 33C and almost no rain (12 mm in January), the right time for walking the quay and the palace grounds.

Hot season
March - May

Afternoons reach 35C and nights stay near 26C; sightsee before 10:00 and after 16:00 and spend midday in museums or cafes.

Wet season
June - October

Rain peaks in September at around 270 mm, mostly as short, heavy late-day storms that flood low streets for an hour or two.

Planning tip

Khmer New Year in mid-April empties the city as people head to their home provinces, so many shops close and buses out are full. The Water Festival (Bon Om Touk) in October or November brings boat races and huge crowds to the riverfront.

Getting there

Techo airport, buses, trains and Mekong boats

Techo International Airport took over all Phnom Penh flights in September 2025, nearly 20 km from the riverfront; leave a generous margin, as the road jams. The Airport Express Bus runs 05:30 to 23:30, about an hour, exact fare in riel. Coaches arrive at company depots, and fast boats come up the Mekong from Chau Doc.

Airport Express Bus
05:30 to 23:30 with frequent departures; about an hour to Kouch Kanong Roundabout via AEON Mall 3 Mean Chey, exact fare in riel only
Bus stop
Signposted from the arrivals hall; the information desk can point the way
Taxi, Grab or PassApp
Quicker than the bus outside rush hour; pay with small, undamaged notes
Train to Battambang
One departure a day at 06:40, arriving around 13:00
  • Download the free City Bus app before landing and search AEB to see where the next airport bus is.
  • Show the driver each dollar note before you hand it over and wait for a nod, because torn notes are refused and a known scam involves ripping one out of sight.
  • Grab, PassApp and taxis are quicker than the bus outside rush hour.
  • The Royal Railway runs to Battambang, Kampot and Sihanoukville.

Know before you go

What makes Phnom Penh worth the trip, and what catches visitors out.

Why travelers love it

  • The National Museum courtyard, a quiet garden with lily ponds at the centre of the galleries, good for a pause between rooms of Angkor sculpture.
  • The Silver Pagoda, with its silver-tiled floor and Emerald Buddha inside the palace grounds.
  • A sunset boat on the Mekong, looping past the confluence as the city lights come on.
  • The Central Market dome, a 1930s Art Deco hall still busy with jewellers and fabric stalls.
  • Independence Monument after dark, the lotus-shaped tower at the head of Norodom Boulevard lit up over the evening traffic.

Good to know

  • Cover shoulders and knees for the Royal Palace and pagodas, or you will be turned away at the gate.
  • Snatch thefts happen in daylight; hold bags on your lap in tuk-tuks and never wear a backpack on a moto.
  • Pavements belong to parked motorbikes and food stalls away from the quay, so expect to walk in the road and watch the traffic.
  • Scammers work the riverfront and Hun Sen Park, often opening with friendly chat that ends in a request for money.

Two days in Phnom Penh, from the Royal Palace to Tuol Sleng

Give Phnom Penh two days. The first is the royal city: the Royal Palace and Silver Pagoda at opening time, the National Museum, lunch inside the Central Market, then Sisowath Quay to Wat Phnom and an evening boat. The second morning belongs to Tuol Sleng and the killing fields.

Day one is for the royal city. Be at the Royal Palace gate at opening time, while the courtyards are still cool, and finish inside at the Silver Pagoda with its floor of silver tiles. Walk a few minutes north to the National Museum, where the seated Jayavarman VII and the Leper King deserve a slow look, then rest in the central garden. Lunch on noodle soup at the counters inside the Central Market and look up into the dome before you leave.

As the heat eases, follow Sisowath Quay north to Wat Phnom, the small hill temple that gave the city its name, and board an evening boat on the Mekong to watch the lights come on along the shore.

Give the second morning to Tuol Sleng and Choeung Ek. A remork driver can take you to both and wait while you go round, and the audio guides are the best way to take them in. Plan nothing demanding afterwards: lunch and a browse at the Russian Market, a slow coffee in BKK1, then an evening stroll through the gardens east of Independence Monument.

Bai sach chrouk breakfasts and Russian Market grazing

Breakfast in Phnom Penh is bai sach chrouk, charcoal-grilled pork on broken rice with pickles, from street stalls that pack up by mid-morning, or kuy teav, the clear pork noodle soup that carries the city's name. Num banh chok, rice noodles in green fish curry, sells at the same hour; graze the Russian Market food hall later.

Mornings belong to bai sach chrouk, thin slices of pork grilled over charcoal and laid on broken rice with pickled vegetables and a small bowl of broth. Stalls set up on street corners at dawn and pack away by mid-morning. The other breakfast staple is kuy teav, a clear rice-noodle soup with pork and fresh herbs, and the capital's style of it carries the city's name all over the country. Num banh chok, rice noodles under a green fish curry, is sold from baskets at the same hour.

Markets are the places to graze. The Russian Market has a cramped food hall under its tin roof, the Central Market keeps noodle counters around the dome, and after dark the night market near the quay fills with mats and grills.

For adventurous eaters, the corner of Street 178 and Norodom Boulevard sells duck embryo eggs and whole battered frogs, and the Central Market has grilled skewers of pig ears and gizzards. The city also has the widest spread of French, Vietnamese, Thai and regional Chinese kitchens in Cambodia. Iced coffee with condensed milk is everywhere, and independent roasters now compete with the international chains.

Cool December, a 35°C April and the autumn storms

December and January are the gentlest months, with highs of 31 to 32°C and barely any rain. April reaches 35°C with 26°C nights, and September and October are wettest, at about 270 and 250 mm, in heavy late-day storms. Khmer New Year in mid-April empties the capital and closes many shops.

The calendar splits cleanly. December and January are the gentlest months, with highs of 31 to 32C, lows around 22C and barely any rain. By April the afternoon high sits at 35C and nights stay at 26C, which makes midday sightseeing hard work. Rain builds from May, and September and October are the wettest months at around 270 mm and 250 mm, usually arriving as heavy late-day storms that drain within a couple of hours.

Festivals change the city more than the weather does. Khmer New Year in mid-April empties the capital as families travel to their home provinces, and many shops and restaurants close for several days. Pchum Ben, the festival of the ancestors, has a similar effect in September or October, with pagodas full of rice offerings at dawn.

Bon Om Touk, the Water Festival, falls in October or November and celebrates the moment the Tonle Sap reverses its flow. Long racing boats crewed by dozens of paddlers compete on the river in front of the Royal Palace, and the quay is packed for three days. Book rooms early if your dates overlap, and expect road closures near the river.
