The capital does contradiction well: a gilded royal palace, a genocide museum you will not forget, and a riverfront that drinks until late.
Royal Palace and Silver Pagoda
The Throne Hall and a pagoda floored in silver tiles, holding the crystal Emerald Buddha. Cover shoulders and knees or you will not get in.
Tuol Sleng Genocide Museum
The school the Khmer Rouge turned into S-21 prison. Open 8am to 5pm. Take the audio guide, allow two hours, keep the afternoon quiet.
Choeung Ek Killing Fields
Fifteen kilometres out of town, the execution site that S-21 fed. A memorial stupa, a field of hollows, and an audio tour that carries it.
National Museum of Cambodia
Terracotta halls around a courtyard, holding the finest Angkorian sculpture in the country. A useful primer before or after Siem Reap.
Riverfront and Central Market
Sisowath Quay for sunset and a drink, then the yellow art-deco dome of Psar Thmey for silverwork, watches and cheap lunch counters.
Fly into Techo (KTI)
Techo International opened in 2025 and now takes all international flights, 20km south of the city. Old PNH keeps domestic and private jets.
Bus from Siem Reap or Kampot
Six to seven hours from Siem Reap, three to four from Kampot. Operators like Giant Ibis run comfortable coaches with assigned seats.
Boat or bus from Vietnam
The Mekong crossing at Kaam Samnor links to Chau Doc; road buses to Ho Chi Minh City take six to seven hours via the Bavet border.
Best time to go
November to February: dry, and the Water Festival fills the riverfront.
Cheapest months
June to September, when rain clears the streets and hotel rates drop.
Priciest & busiest
December, January, and the Water Festival week in November.
Morning
Royal Palace and the Silver Pagoda at opening, before the heat and the tour coaches arrive.
Late morning
Cross to the National Museum for Angkorian statues in a cool, breezy courtyard.
Lunch
Khmer curry or a baguette near the riverfront; the French bakery habit never left town.
Afternoon
Tuol Sleng, then the drive out to Choeung Ek. Heavy, essential, and best done in one run.
Evening
Sunset on Sisowath Quay, dinner in Bassac Lane, and rooftop bars that stay open late.
