Phnom Penh
Choeung Ek / Toul Sleng Area

Cambodia's most sobering pilgrimage — S-21 and the Killing Fields are in the southern suburbs, best paired with quiet reflection.
The Tuol Sleng Genocide Museum (S-21), where the Khmer Rouge operated a systematic detention and torture facility between 1975 and 1979, occupies a former school in the Tuol Svay Prey area; the Killing Fields of Choeung Ek, where the majority of S-21's prisoners were executed and buried, lies 15km south in what is now a peaceful rural suburb connected by tuk-tuk. Neither site is a neighbourhood in the conventional sense — they are destinations for a specific and necessary kind of reflection on 20th century history. The surrounding streets are quiet, residential, and largely untouched by tourism infrastructure, which gives visits to both sites a stillness appropriate to their significance. Most visitors stay elsewhere and come by tuk-tuk; a small number of guesthouses serve those who prefer to be close.

What you gain
- ↑Tuol Sleng Genocide Museum (S-21) — one of the most important historical sites in Southeast Asia: the preserved classrooms, photographs, and records of the Khmer Rouge's systematic terror are deeply moving and essential context for understanding Cambodia's present
- ↑Killing Fields of Choeung Ek — the memorial stupa filled with skulls, the audio guide narrated by survivors, and the silence of the mass grave sites make for a profoundly impactful visit; allow 2–3 hours and arrive before the tour groups from Siem Reap
- ↑The surrounding residential streets offer the most unmediated view of everyday Cambodian life in the city — vegetable markets, schoolchildren, monks on morning rounds — completely removed from any tourist infrastructure
What you sacrifice
- ↓Not a neighbourhood for staying: accommodation is sparse and the sites are separated by 15km; most visitors correctly stay in BKK1 or the riverside and make a dedicated half-day trip
- ↓Not appropriate for young children or visitors who are not prepared emotionally for what S-21 and Choeung Ek require — both sites are viscerally confronting in ways that guidebooks cannot fully convey
- ↓No nightlife, minimal restaurants beyond local Cambodian food stalls, and no cafe culture; this is a destination for daytime visits, not a base
