Phnom Penh surprises almost everyone who arrives expecting a generic Southeast Asian capital. It is smaller than Bangkok, less frenetic than Ho Chi Minh City, and more navigable than Jakarta — a city that moves at a human pace despite its recent rapid growth. The riverfront is genuinely beautiful: the Mekong and Tonle Sap rivers converge here, and the wide promenade along the water feels like a city that knows it has something worth showing.
The history, however, is heavy. The Khmer Rouge emptied Phnom Penh of its entire population in April 1975. In 1979, the city was a ghost town. Understanding this — even at a surface level — changes how you see everything else here. The markets are full because they were once empty. The young population (70% of Cambodia’s 17 million people are under 35) reflects a demographic gap where an older generation was largely destroyed. The food is good because people are rebuilding.
Here is how to spend your time well.
How Long to Spend in Phnom Penh
Minimum useful time: 2 days. Day one: the historical sites (Tuol Sleng and Killing Fields). Day two: the Royal Palace, riverfront, and markets. Rush it any more than this and you will feel like you have only grazed the surface.
Ideal time: 3 days. Adds time for the National Museum, a riverboat evening, a day trip to Udong or Koh Dach island, and the slower pleasures of the city.
Avoid: Using Phnom Penh purely as a transit hub and spending fewer than a day. The history alone deserves respect and time.
Day One: Understanding the History
Tuol Sleng Genocide Museum (S-21)
Tuol Sleng was a high school that the Khmer Rouge converted into a security prison (S-21) in 1975. An estimated 17,000 people were imprisoned here between 1975 and 1979. Fewer than a dozen survived. The classrooms were divided into individual cells. The school grounds became an interrogation center.
The museum preserves the site largely as it was found in 1979. The photographs of prisoners — systematic intake photographs taken of everyone who entered — fill wall after wall. The former classrooms display rusted iron beds and torture implements. The genocide is not abstracted or sanitized here. It is presented directly, which is the only appropriate response to what happened.
Practical: Open daily 8am-5pm. Entry $10. Guided audio tours $3 (worth it). Allow 2-3 hours. It is emotionally difficult — take breaks in the courtyard, drink water, and do not rush yourself through it.
The Killing Fields of Choeung Ek ($6 entry)
Located 15 kilometers south of the city, Choeung Ek is one of hundreds of killing fields where Khmer Rouge prisoners were executed and buried. The audio guide (included in entry, presented in the voice of a survivor) leads you through the site in approximately 90 minutes. Mass graves are visible throughout the grounds. A glass stupa at the center contains the exhumed remains of over 8,000 victims, arranged by bone type — an act of commemoration that is deeply confronting and deeply important.
Practical: Take a tuk-tuk from Tuol Sleng ($5-8 each way). The two sites together take a full morning. Give yourself the afternoon to process.
Note on sequence: Visit Tuol Sleng first, then Choeung Ek. The timeline of events moves from imprisonment to execution, and understanding S-21 first gives context to Choeung Ek.
Day Two: The Surviving Beauty
Royal Palace and Silver Pagoda ($10 entry)
The Royal Palace complex occupies a prominent position along the riverfront and contains some of the most spectacular Khmer architecture in Cambodia. Unlike Angkor, these buildings are still in active royal use — portions of the palace are off-limits because the king actually lives there.
The Silver Pagoda, within the palace grounds, gets its name from its floor — 5,000 silver tiles, weighing a ton each, cover the floor of the temple hall. Inside, a life-sized gold Buddha encrusted with 9,584 diamonds and an emerald Buddha from the 17th century are the centerpieces of a treasury of royal offerings and historical artifacts.
Practical: Open daily 8am-11am, 2pm-5pm. Entry $10. Dress code strictly enforced — shoulders and knees covered. Allow 2 hours.
National Museum of Cambodia ($5 entry)
A terracotta-colored building one block north of the Royal Palace that houses one of the world’s finest collections of Khmer art — bronzes, stone sculptures, and ceramics spanning from the pre-Angkor period to the 12th century. The collection includes pieces removed from Angkor for preservation that you will not see at the temples themselves. Entry is $5 and the museum is genuinely excellent — less crowded than you would expect and more impressive than most visitors anticipate.
Practical: Open daily 8am-5pm. Allow 1-2 hours. The garden courtyard with its Buddhist nagas and pond is a peaceful spot for a break.
The Riverfront and Sisowath Quay
The wide promenade along the Mekong is Phnom Penh at its most scenic. Walk north from the Royal Palace toward Wat Phnom (a small hill temple that is the city’s origin point), or south past the Foreign Correspondents’ Club (FCC) — now a restaurant with a legendary rooftop terrace — to the tourist precinct. The riverfront in the late afternoon, when locals emerge for their evening stroll and vendors set up along the promenade, captures Phnom Penh’s recovery and energy in the most immediate way possible.
Central Market (Phsar Thmei)
An extraordinary art deco building from the 1930s — a yellow-domed central hall with four wings radiating outward like a compass — that remains the city’s central market. The ground floor sells gold and silver jewelry, watches, and currency. The wings contain fabric, fresh produce, street food, and everything else. The street food stalls outside the main dome serve excellent noodle soup, fresh spring rolls, and Cambodian pastries for $1-2.
Where to Eat in Phnom Penh
Romdeng (street 278): A social enterprise restaurant serving Cambodian country cooking — ant-egg salad, tarantula fritters if you’re brave, river fish with fermented shrimp paste — in a restored colonial villa with a garden. Run by Mith Samlanh (Friends International), which works with street youth. The food is extraordinary and your money does something useful. Book ahead: +855 92 219 565.
The Khmer Kitchen (near Riverside): Excellent value Khmer food in a casual setting. The beef lok lak ($4.50), fish amok ($5), and fresh spring rolls ($2.50) are all excellent. Friendly service and a menu in English, Khmer, and French.
Riverside Bistro (Sisowath Quay): An expat institution with decent Western food and one of the best sunset terraces on the riverfront. Not cheap by Cambodian standards ($10-20/person) but the location earns it.
Local Noodle Soup (street vendors, markets): For $1.50-2, a bowl of noodle soup from a market stall is the best breakfast in Cambodia. The thick rice noodles with pork, fresh herbs, lime, and chili eaten at a plastic stool while watching Phnom Penh wake up is irreplaceable.
Where to Stay in Phnom Penh
Budget: Mad Monkey Hostel ($8-12 dorm, $20-30 private): A well-run backpacker hostel near the riverfront with a rooftop bar, organized social activities, and reliable air conditioning. Good for meeting people and easy for solo travelers.
Mid-range: The Plantation ($50-90/night): A boutique hotel in a renovated colonial building near the National Museum. Beautiful pool, genuinely helpful staff, and rooms that feel luxurious at the price point. My recommendation for mid-range travelers.
Upscale: Raffles Hotel Le Royal ($250+/night): The legendary hotel where Jacqueline Kennedy and Charles de Gaulle once stayed. Beautifully restored colonial grandeur. Worth having a drink at the bar even if you’re not staying.
Getting Around Phnom Penh
Grab works throughout the city and is the most convenient option. A typical tuk-tuk within the central area runs $2-4. Grab cars (standard taxis) are available for about $5-8 for longer distances. Walking works well along the riverfront and between the main sights.
Avoid renting a motorbike unless you are an experienced rider — Phnom Penh traffic is chaotic and accident rates are high.
Safety in Phnom Penh
Phnom Penh is generally safe for tourists, but theft is a real concern. Bag snatching from motorbikes occurs on the riverfront and in the tourist areas. Keep bags on your inland shoulder (not the road side) when walking, don’t flash expensive electronics, and be aware of your surroundings at night. The riverfront is fine for evening strolls; avoid poorly lit streets in non-tourist areas after dark.
One Thing Many Travelers Overlook
The Phnom Penh night markets. Every Friday and Saturday evening, a large open-air night market sets up along the riverfront north of Wat Phnom. Food stalls serve Cambodian street food, craft vendors display locally made goods, and musicians play traditional Khmer music. It is Phnom Penh as the city wants to be seen — vibrant, recovering, looking forward — rather than only through the lens of its worst decades. Don’t leave without spending an evening here.
