Why the route runs from Angkor to Hanoi
Starting in Cambodia puts the most physical day first. The temple day is spent largely on foot in tropical heat, and it is easier while you are fresh. Going one way also means no leg is covered twice.
It is shorter than the two weeks or more that most combined tours of Vietnam and Cambodia take. For visas, budgets and the wider picture, read our guide to planning a Vietnam and Cambodia trip from the UK.
When is the best time for a Vietnam and Cambodia tour?
The route crosses three climates, and no single month suits all of them. November to February is the most reliable overall.

Flights from the UK and the airports you use
There is no non-stop flight from the UK to Cambodia, so the outbound connects en route, and you fly home from Hanoi.
Both Cambodian airports on the route are new. Siem ReapโAngkor International opened in October 2023, about 50 km east of town, and Phnom Penh flights moved to Techo International on 9 September 2025.
