Leaving the ancient stone faces of Angkor for the motorbike-filled streets of Hanoi takes you from the spiritual heart of Cambodia to the historic soul of Vietnam. Siem Reap's dusty, laid-back charm gives way to the cool colonial elegance and frantic energy of the Vietnamese capital, and the aroma of street-side pho replaces jungle temples.
With an international border and a long road between the two cities, flying is the only practical way to make this trip without days on buses. You can have breakfast in Siem Reap and a sunset stroll around Hoan Kiem Lake in Hanoi the same afternoon.

Tips for Traveling from Siem Reap to Hanoi
- Visa: Check whether you need a visa for Vietnam before you fly. If you do, apply on the official Vietnamese e-visa portal, because e-visas work only at approved border gates.[4]
- Currency: US dollars circulate widely in Siem Reap, but you will need Vietnamese dong in Hanoi, and the arrivals hall at Noi Bai International Airport has ATMs and exchange booths.
- Climate: From November to February Siem Reap is hot, while Hanoi can be chilly and misty, so keep a light jacket in your carry-on.
- Airport Transfers in Hanoi: Noi Bai Airport lies outside the city. A ride-hailing app or a pre-booked shuttle is more reliable than picking a taxi at the curb.
