From Sihanoukville: Phnom Penh Tuol Sleng & Killing Fields

Travel from Sihanoukville to Phnom Penh. Visit the Tuol Sleng Genocide Museum and the Choeung Ek Killing Fields, and choose to be dropped off at your hotel, the city center, or the airport.
Begin your journey in Sihanoukville and travel overland to Phnom Penh for a deeply reflective day focused on two of Cambodia’s most important memorial sites from the Khmer Rouge era.

Visit the former high school that became the notorious S-21 prison, now the Tuol Sleng Genocide Museum. Once a secondary school in central Phnom Penh, this complex was transformed by the Khmer Rouge into Security Prison 21 between 1975 and 1979. Classrooms were converted into tiny cells and interrogation rooms. Walls lined with black-and-white prisoner photographs, preserved instruments, and the original buildings offer a stark, firsthand view of the systematic detention and suffering that took place here. Only a handful of the estimated 14,000–20,000 people who entered survived.

Continue to the Choeung Ek Killing Fields, located about 15–17 km south of the city. This former orchard and Chinese cemetery became the main execution site linked to S-21. Prisoners were brought here, mostly at night, and killed before being buried in mass graves. A tall memorial stupa now houses thousands of skulls and bones recovered from the site, while excavated pits, pathways, and an audio guide help visitors understand the scale of what occurred. The grounds remain quiet and solemn, serving as a place of remembrance.

The tour ends with a convenient drop-off either in the city center or at Techo International Airport, making it ideal for travelers connecting onward.
