Build one good day first
The useful plan is Royal Palace and riverside first, Central Market nearby, Tuol Sleng as a separate respectful block.
- Anchor the day around Royal Palace or Silver Pagoda.
- Keep Wat Phnom for the right weather and timing.
The best things to do in Phnom Penh are not just a list of names. They need order, weather sense, and a landing point. I would start with the anchor that defines the day, then add food, shopping, or a quieter area only when it helps the rhythm.
The practical rule is simple: Royal Palace and riverside first, Central Market nearby, Tuol Sleng as a separate respectful block. That keeps the day grounded instead of making it feel like a loose checklist.
