Places most visitors miss, many of them free.
One of Phnom Penh's five original pagodas, located in a quiet compound near the Independence Monument. It's a working monastery and meditation center.
Tucked in a corner of the Russian Market, this small stall is packed with genuine vintage items from Cambodia's recent past.
A tiny, hidden alleyway in BKK1 that transforms at night into a vibrant strip of minuscule, themed cocktail bars and eateries.
A striking, salmon-painted Catholic church built in the 1960s, standing as a rare example of modernist architecture in the city.
A larger, less-visited island in the Mekong upstream from the city, known for its pottery villages and quiet rural life.
1.5 hours by car/tuk-tuk
The former royal capital of Cambodia, Oudong is a serene hilltop complex of stupas and temples offering panoramic views of the plains. It's a deeply spiritual site for Cambodians and a peaceful escape from the city.
30-45 minutes by tuk-tuk + 5-minute ferry
A rustic island in the Mekong River where life moves at a slower pace. It's famous for its traditional silk-weaving villages, where you can see the entire process from silkworm to finished scarf.
2 hours by car
An 11th-century Angkorian temple ruin perched on a hill, offering a more intimate and less-crowded alternative to the temples of Siem Reap. The climb up the ancient steps is rewarded with stunning views and well-preserved sandstone carvings.
Top sights include Royal Palace & Silver Pagoda, Tuol Sleng Genocide Museum, Killing Fields of Choeung Ek and Central Market. Away from the crowds, try Wat Langka and The Vintage Shop at Russian Market.
