Phnom Penh

15 Best Killing Fields & S21 Tours

This page gathers tours that pair Tuol Sleng, the Phnom Penh school the Khmer Rouge turned into the S21 prison, with the killing fields at Choeung Ek, about 15 kilometres south. These are places of genocide remembrance; go to bear witness, not to sightsee. A calm guide, and time to sit quietly afterwards, matter more here than anywhere else in the city.
