Leaving the chaotic charm of Hanoi's Old Quarter for the ancient majesty of Angkor Wat is a journey that takes you from the heart of northern Vietnam to the spiritual soul of Cambodia. While both cities share a deep sense of history, the transition is stark: you swap the narrow, steaming pho stalls and buzzing motorbikes of the Red River Delta for the dusty, sun-drenched plains and sandstone spires of the Khmer Empire. It is a route favored by those looking to contrast the French colonial architecture of Vietnam with the grand archaeological wonders of Cambodia.
Because of the significant distance and the international border between Vietnam and Cambodia, air travel is the only practical way to complete this journey without spending several days on multiple buses. This route connects two of Southeast Asia's most iconic UNESCO World Heritage destinations, making it a high-demand corridor for travelers exploring the Indochina region.
Hanoi to Siem Reap by Flight
Flying is the most efficient and popular method to reach Siem Reap from Hanoi. The journey covers approximately 850 kilometers, and crossing by air saves you from the logistical headache of overland border crossings through Laos or southern Vietnam. Prices for this route typically range from $66 to $327, depending on how far in advance you book and which airline you choose. The shortest direct flights clock in at just 1 hour and 50 minutes, while indirect routes with layovers can take up to 14 hours.
Direct Flights vs. Connecting Flights
Direct flights are operated by full-service carriers like Vietnam Airlines and Cambodia Angkor Air. These flights are highly recommended because they get you to the temples of Angkor in under two hours, leaving you with plenty of energy for a sunset visit to the ruins. When you book a direct flight, you usually fly into the new Siem Reap-Angkor International Airport (SAI), which is located further from the city center than the old airport but offers modern facilities and smoother immigration processes.
Connecting flights often involve a stopover in cities like Luang Prabang, Bangkok, or Ho Chi Minh City. While these can sometimes be cheaper if booked during a promotion, the total travel time increases significantly. If you choose an indirect route, pay close attention to the layover duration; some connections are short enough to be convenient, while others might leave you waiting in a transit lounge for half a day. You can easily compare these different flight durations and prices on GoAsia.cc to find the itinerary that fits your schedule.
The Flight Experience
Most flights on this route offer Economy Class seating. On direct flights, the service is quick but professional. Given the short duration of the direct hop, you might receive a light snack or just water, while longer connecting flights on full-service airlines will typically include a meal. Both Hanoi's Noi Bai International Airport and Siem Reap's new airport are well-equipped with lounges, duty-free shops, and dining options. Remember that you are traveling between two different countries, so ensure your passport is ready for the immigration desks at both ends.

Tips for Traveling from Hanoi to Siem Reap
- Visa Requirements: Most nationalities require a visa for Cambodia. You can apply for an e-visa online before you depart Hanoi to speed up the process at the airport, or check if your nationality is eligible for a visa on arrival.
- Airport Transfer: The new Siem Reap-Angkor International Airport is about 45-50 kilometers from the city center. Budget at least an hour for the taxi or shuttle bus ride to your hotel.
