Hanoi to Siem Reap Travel Guide: Best Ways to Get & Tour Ideas

Flying from Hanoi to Siem Reap is the quickest way to travel between the two cities. Still, flying isn’t the only travel option. Many travelers choose to travel from Hanoi to Siem Reap by bus, private car, or a mix of transport methods to experience more of the countryside, local culture, and hidden towns along the way.

Both routes have their advantages and disadvantages. In this guide, you’ll find clear details about routes, flight schedules, and practical travel tips for moving smoothly from Vietnam’s capital to Cambodia’s temple city.

How Far is It from Hanoi to Siem Reap? Distance on the Map

The distance between Hanoi and Siem Reap depends on how you travel on your Cambodia and Vietnam tours. By air, the distance from Hanoi to Siem Reap is roughly 900 kilometers. If you choose to travel overland, the distance stretches to more than 1,200 kilometers. It’s easy to understand when looking at a map of Vietnam and Cambodia.

The difference in travel time between flying and going overland is also quite large. A direct flight takes about 1.5 hours, while a bus or car journey can take 24 to 36 hours, depending on stops, connections, and border checks. Travelers who prefer comfort and limited travel time usually fly, while those who enjoy long routes and slow travel take the road.

There are two main overland routes used by travelers. The first passes through Ho Chi Minh City and crosses the border at Moc Bai–Bavet, which is the most common and convenient option. The second route goes through Phnom Penh, Cambodia’s capital, before continuing north to Siem Reap. Some travelers combine both options—flying part of the way and then taking buses or cars to explore the countries more.

Hanoi to Siem Reap Flights: The Fastest & Most Convenient Way

Flying from Hanoi to Siem Reap offers the quickest connection between these two cities when traveling from Vietnam to Cambodia. Direct flights operate several times per week, making this option accessible for most travelers.

Airlines serving this route include Vietnam Airlines, Cambodia Angkor Air, and occasionally other regional carriers. Flight schedules can vary by season, with more frequent departures during peak tourist months from November to March.

Note: Flight schedules are subject to change. Always check with airlines for current availability and times.

The average cost of Hanoi to Siem Reap flights usually falls between $100 and $250 USD for a one-way ticket. Fares change based on the season, how early you book, and ongoing airline promotions. Sometimes, budget airlines release limited-time deals with prices dropping below $100, while flights during major holidays or peak months can be on the higher end.

To find cheaper fares, it helps to plan ahead. Booking your ticket 4–6 weeks in advance often gives you the best rates. Traveling on weekdays instead of weekends and keeping your dates flexible can make a big difference in cost—sometimes saving enough to cover a night’s stay in Siem Reap.

Hanoi to Siem Reap by Bus or Overland: For Adventurous & Slow Travelers

Traveling from Hanoi to Siem Reap by bus or road is possible, but it’s a long and challenging trip. There is no direct bus between the two cities. The route usually involves three stages: from Hanoi to Ho Chi Minh City, then Ho Chi Minh City to Phnom Penh, and finally Phnom Penh to Siem Reap.

The first leg, Hanoi to Ho Chi Minh City, takes about 30–35 hours by bus, though many travelers prefer to fly or take a train for a Vietnam tour. From Ho Chi Minh City to Phnom Penh, buses take 6–7 hours, and from Phnom Penh to Siem Reap, another 5–6 hours. Altogether, traveling overland can take 24 to 36 hours or even longer if you stop along the way.

Several advantages make the Hanoi to Siem Reap bus option appealing. Cost stands as the primary benefit. The entire overland journey can cost as little as $50-80 USD, a fraction of flight prices. You get to see the Vietnamese and Cambodian countryside firsthand.

The disadvantages are equally clear. Long hours on buses get uncomfortable. Seats may lack legroom, and rest stops are infrequent. Border formalities at Moc Bai-Bavet can be slow and confusing. Scammers sometimes target tourists during border crossings. The physical exhaustion from 24+ hours of travel mean you'll need a recovery day before serious sightseeing.

This option suits backpackers who want to travel Vietnam and Cambodia in budget or who have plenty of time. Slow travelers who enjoy the journey as much as the destination find this route rewarding. If you want to claim you've truly traveled from north to south through Vietnam and into Cambodia, this is your chance.

Tourists can take the bus from Ho Chi Minh City to Phnom Penh.

Private Car or Combined Transfer from Hanoi to Siem Reap: Best for Families & Groups

A private car or combined transfer is another option, though it’s usually part of a larger Vietnam Cambodia tour rather than a single journey. This route often follows a path like Hanoi – Ho Chi Minh City – Phnom Penh – Siem Reap, allowing for stops in key destinations such as Hue, Hoi An, and the Mekong Delta.

A typical 2-week Vietnam and Cambodia tour route covers Hanoi to Ho Chi Minh City first, often with stops in Hue or Hoi An. From Ho Chi Minh City, you cross into Cambodia at the Moc Bai-Bavet border. The journey continues through Phnom Penh before reaching Siem Reap.

Price ranges vary widely based on vehicle type and tour inclusions. A basic private car transfer costs $800-1,200 USD for the full route. Luxury vans with more stops and better hotels can reach $2,000-3,000 USD. The per-person cost drops significantly for groups of 4-6 people, making this option quite economical when shared.

Families with children benefit most from private transfers to visit Vietnam and Cambodia. Parents appreciate the flexibility to adjust schedules around kids' needs. Groups of friends find the cost comparable to first-class bus tickets when split among several people. Older travelers who want comfort without the hassle of flight connections also prefer this method.

Just bring a light raincoat or umbrella and plan temple visits in the morning when the weather is clearer.

For all seasons, wear light and breathable clothes, comfortable shoes, and carry insect repellent. In Siem Reap, mornings are best for exploring Angkor Wat before the heat rises, while Hanoi is perfect for evening walks around Hoan Kiem Lake.

Travel Tips for Traveling from Hanoi to Siem Reap

Before traveling from Hanoi to Siem Reap, it’s important to check visas for Vietnam and Cambodia. Most travelers can apply for an e-visa online before departure or get a visa on arrival at major airports and land borders. The visa fee is around $30–$35, payable in US dollars. Keep a few passport photos ready and make sure your passport is valid for at least six months.

When crossing the border by bus or car, stay cautious at checkpoints. Some agents may try to charge extra for forms or “express” services. Always confirm official fees and use trusted transport companies with good reviews.

For packing, keep things light. Both cities are warm for most of the year, so breathable clothing is best. A hat, sunscreen, and insect repellent are must-haves. A light rain jacket comes in handy between July and October.

Always carry some cash, as smaller vendors and tuk-tuk drivers in Cambodia may not accept cards. ATMs are available in both cities, but having small notes helps with tips and local snacks, especially when considering the Currency for Vietnam and Cambodia tour.
