Phnom Penh was our entry and exit point into Cambodia, and we spent 3.5 days exploring its many layers. From confronting the country’s darkest history at the Killing Fields and Tuol Sleng, to wandering through royal palaces, busy markets, riverside promenades, and street food stalls, this guide shares our experience of Phnom Penh with kids, where to stay, what to see, and what stayed with us long after we left.
