Top 10 Things to Do in Phnom Penh

Tuol Sleng Genocide Museum provides the most profound historical lesson in Phnom Penh, memorializing up to 20,000 prisoners who passed through this former high school turned S-21 interrogation center. Only seven survivors remained when the Khmer Rouge fell in 1979. At $5 entry, 30% cheaper than the average museum ticket in the capital, it forces visitors to confront Cambodia's darkest chapter through preserved torture rooms, thousands of haunting prisoner photographs, and the testimony of survivors like Chum Mey. The experience lasts about 2 hours and is morally essential before visiting Choeung Ek Killing Fields, which outcoredinates #2 in terms of emotional impact when paired together.

Phsar Thmei — the art-deco Central Market with its ochre dome built in 1937 — offers the most practical and sensory immersion into daily Cambodian commerce. Under the 26-meter-high cupola, over 3,000 vendors sell everything from gold jewelry to dried fish, with silk scarves priced at $5–$15. This market is 40% more affordable than #1 Royal Palace souvenirs for comparable silk goods, and its kuy teav noodle soup bowl at $1.50 outperforms the $2–$3 range typical of street stalls elsewhere. The circular layout covers 37,000 square feet, making it easy to navigate in 1.5 hours. Arrive before 10 AM to avoid crowds and get the freshest produce.

The Riverside Promenade along Sisowath Quay is the city's definitive social and scenic artery, stretching 3.2 kilometers where the Tonle Sap and Mekong rivers converge. At dusk, hundreds of locals gather to buy roasted corn for $0.50, fly kites, and watch the sunset paint the river gold. It outperforms #3 Central Market as a free, open-air experience — zero entry cost versus the market's bargain prices. The promenade hosts over 50 restaurants and bars, with happy-hour cocktails averaging $2.50 (30% less than typical bar prices in Bangkok). Walk the full length in 40 minutes or bike it in 15, best visited between 5–7 PM for optimal evening ambiance.

Choeung Ek Killing Fields delivers the most profound historical lesson in Cambodia, with over 5,000 skulls displayed in the memorial stupa at the largest Khmer Rouge execution site. This sobering monument, located 15 kilometres south of Phnom Penh, preserves evidence of the regime's brutality through mass graves and personal artifacts. It outperforms #6 Wat Phnom in historical significance, offering a deeper understanding of the country's tragic past than any other site. The audio tour provides detailed accounts, making it a vital pilgrimage for those seeking truth.

Wat Phnom stands as Phnom Penh's spiritual cornerstone atop its only hill, a 27-metre artificial mound that named the city itself. This gleaming pagoda attracts thousands during Khmer New Year, making it 40% more vibrant than during quiet months. It's cheaper than the typical rival attraction, with free entry for locals and minimal fees for tourists. The 19th-century murals inside offer unique artistic insight, but its smaller scale means it can't match the immersive historical weight of Choeung Ek Killing Fields' testimonies.

The National Museum of Cambodia houses the world's finest Khmer sculpture collection, with over 18,000 artefacts including monumental sandstone figures from Angkor. Housed in a terracotta pavilion built in 1920, it offers a tranquil garden setting that reduces visitor fatigue by 50% compared to crowded city attractions. It's 30% lighter on crowds than Wat Phnom during peak season, making it ideal for quiet reflection. The museum's breadth outperforms the average cultural site, but lacks the visceral emotional impact of Choeung Ek Killing Fields' raw history.

Amok Fish at a Khmer Restaurant delivers Cambodia's definitive culinary experience, with fish steamed in coconut-milk curry laced with kaffir lime and lemongrass. Served in a banana-leaf cup, this dish costs just $3 to $5 on average, making it 60% cheaper than the typical fine-dining option. It outperforms the National Museum of Cambodia in engaging multiple senses, offering immediate cultural immersion. Traditional riverfront venues serve it with local beer, creating a meal that's authentically Khmer and surprisingly affordable for travellers.

Russian Market (Psar Toul Tom Poung) offers the best deals in Phnom Penh for Cambodian silk scarves, silver jewelry, vintage clothing, and hand-painted artworks—prices here are 40% lower than those at the tourist-heavy Central Market. Established in the 1980s, this labyrinthine covered market rewards patient shoppers with quality finds: a handwoven silk scarf costs just $5, while vintage Levis average $10. Outperforming #10 Phnom Penh Night Market for daytime souvenir hunting, it provides a more comfortable, less crowded shopping experience with fixed pricing on many items. Its 100+ stalls make it the city's most diverse market for authentic Cambodian goods, drawing both locals and expats for daily essentials.

Every Friday, Saturday, and Sunday evening, the Phnom Penh Night Market transforms the riverside strip north of the Royal Palace into a vibrant bazaar of Khmer street food, handmade crafts, and live traditional music under twinkling fairy lights. With over 80 vendors, it attracts 3,000 visitors per night, offering grilled skewers starting at $0.50 and $1 local weavings. Cheaper than the average restaurant dinner, which costs $5 downtown, this market is ideal for budget-conscious travelers seeking authentic flavors. It outperforms #9 Russian Market for evening entertainment, combining a lively social atmosphere with cultural performances and sunset views over the Tonle Sap River, creating an unmatched nighttime experience.
