Leaving behind the ancient stone faces of Angkor Wat for the buzzing, motorbike-filled streets of Hanoi marks a transition from the spiritual heart of Cambodia to the historic soul of Vietnam. While both cities are deeply rooted in heritage, the atmosphere shifts dramatically from the dusty, laid-back charm of Siem Reap to the cool, colonial elegance and frantic energy of the Vietnamese capital. This journey bridges two of Southeast Asia's most iconic destinations, trading jungle temples for the aroma of street-side pho and the mist-covered lakes of the north.
Because of the significant distance and the international border between Cambodia and Vietnam, flying is the only practical way to make this trip without spending several days on multiple buses. The route is well-served by regional carriers, making it a seamless hop that allows you to have breakfast near the Tonle Sap lake and enjoy a sunset stroll around Hoan Kiem Lake the very same afternoon.
Siem Reap to Hanoi by Flight
Taking a flight is the most efficient and popular method to travel between these two hubs. The journey spans roughly 850 kilometers, crossing over the lush landscapes of Laos or the Gulf of Tonkin depending on the flight path. For most travelers, the convenience of a direct flight far outweighs any other land-based alternatives, which would involve grueling transfers through central Vietnam or Laos.
Flight Duration and Experience
The time spent in the air is remarkably short, with direct flights taking between 1 hour 40 minutes and 3 hours 10 minutes. When you factor in the time for check-in and immigration at both ends, the total travel day is manageable and relatively stress-free. Most flights on this route are operated by full-service carriers like Vietnam Airlines or regional specialists such as Cambodia Angkor Air.

Most aircraft serving this route are modern narrow-body planes like the Airbus A321, offering a comfortable standard of seating for the short hop.

Tips for Traveling from Siem Reap to Hanoi
- Check your Visa Requirements: Most nationalities require a visa for Vietnam. Ensure you have your e-visa printed or your visa-on-arrival approval letter ready before heading to Siem Reap International Airport (SAI).
- New Airport Location: Remember that the Siem Reap-Angkor International Airport is located about 45 kilometers from the city center. Allow at least an hour for the journey from your hotel to the terminal.
- Currency Exchange: While USD is widely used in Siem Reap, you will need Vietnamese Dong (VND) once you land in Hanoi. There are several ATMs and exchange booths in the arrivals hall at Noi Bai International Airport.
- Pack for a Climate Change: If you are traveling between November and February, Siem Reap will be hot, but Hanoi can be quite chilly and misty. Carry a light jacket or sweater in your carry-on luggage.
- Airport Transfers in Hanoi: Noi Bai Airport is about 30 kilometers from the Old Quarter. Using a ride-hailing app or a pre-booked shuttle is often more reliable and cheaper than picking a random taxi at the curb.
