How should travellers get around Cambodia?
Cambodia transport is workable, but it is not always elegant. Use tuk-tuks locally, consider private cars when time matters, choose buses carefully and do not make tight plans depend on perfect road days.
Answer
The map makes Cambodia look simple; transport is where that confidence gets tested. Tuk-tuks are useful within towns and around Angkor, but intercity moves need more thought. Buses and vans can be good value when the day has margin; private cars can make sense when a short itinerary cannot afford rough timing. Domestic flights may protect certain routes, but they should be checked against real schedules, not assumed. The best plan is not the cheapest one; it is the one that leaves you functional at the next stop.
Recheck before you go
Transport schedules can change. Check current timings before you book around them.
