Travel by land from Vietnam to Thailand: $35 bus vs $100 flight

A travel by land from Vietnam to Thailand journey presents a budget-friendly alternative to flying across Southeast Asia. Travelers face long transit times and specific border crossing requirements. Proper preparation prevents unnecessary delays and financial scams. Read the details below to navigate the route smoothly and protect your trip.

Yes, you can reach Thailand by land, and it is a classic backpacker rite of passage

Traveling from Vietnam to Thailand overland is not just possible - it is one of the most popular routes in Southeast Asia. This journey involves crossing at least two international borders and requires a bit of logistical planning. There is no direct border between the two countries, so you must transit through either Cambodia or Laos. The choice depends on whether you are starting in the south (Saigon) or the north (Hanoi).

Land travel remains a significant choice for budget-conscious travelers.

In early 2026, roughly 31% of regional travel intent in Southeast Asia focused on these overland routes. While flying takes only 90 minutes, a bus journey spans 18 to 24 hours but cuts costs by nearly 60-70% compared to direct flights. For context, a flight typically costs between $100 and $260 USD, whereas a multi-leg bus ticket averages just $35 to $50 USD. This ^[2] price gap makes the long way attractive for those who value the journey as much as the destination. But there is one specific border scam in Poipet that targets nearly every first-timer - I will explain how to dodge it in the border safety section below.

The most popular route: Ho Chi Minh City to Bangkok via Cambodia

The southern route is the fastest way to get from Vietnam to Thailand by land. Most travelers start in Ho Chi Minh City and take a bus to Phnom Penh, Cambodia, before continuing to the Thai border. This route is well-serviced by several reputable bus companies that handle much of the border paperwork for you. It is efficient, but it can be exhausting if you try to do it all in one go.

I remember my first time on a Cambodian sleeper bus. Being 185 cm tall, I quickly realized these bunks were designed for someone significantly shorter. My knees were perpetually bent, and every time the bus hit a pothole - which was often - I would wake up thinking we had drifted into a river. It was uncomfortable. It was loud. Yet, waking up to see the sunrise over the Cambodian rice paddies made the lack of legroom feel like a fair trade.

Border 1: Moc Bai to Bavet (Vietnam to Cambodia)

The crossing at Moc Bai is generally straightforward. Bus staff usually collect passports at the start of the trip to speed up the group processing. The official visa-on-arrival fee for Cambodia is $30 USD, though ^[4] some agencies might charge a small service fee of $5 USD to handle the queue for you. If you choose to do it yourself, ensure you have crisp, new dollar bills. I once tried to pay with a slightly torn $20 bill, and the officer rejected it as if I had handed him a piece of used tissue.

Border 2: Poipet to Aranyaprathet (Cambodia to Thailand)

Poipet is the most famous border crossing in the region, often for the wrong reasons. It is chaotic, dusty, and full of touts. However, for most Western travelers, entering Thailand is easy. As of 2026, Thailand offers a 60-day visa exemption for citizens of 93 countries. ^[3] You do not need to pay an entry fee, but you must have your Thailand Digital Arrival Card (TDAC) completed on your phone before arriving at the window. Processing times here vary wildly - sometimes you are through in 30 minutes, other times it is a three-hour test of patience.

The Northern Route: Hanoi to Bangkok via Laos

If you are in Northern Vietnam, traveling through Laos is your best bet. This route is significantly more scenic but also more time-consuming. You will likely take a bus from Hanoi to Vientiane, the capital of Laos, which takes about 24 hours. From Vientiane, it is just a short hop across the Friendship Bridge into Nong Khai, Thailand.

The roads in Northern Laos are notoriously winding. If you get motion sickness, this route will be a challenge. I have seen even the most seasoned travelers turn green as the bus navigates the mountain passes. The upside? The views of the limestone karsts and misty valleys are among the best in the world. It is a slow-motion adventure that requires a sturdy stomach and a good playlist.

Border Safety and Avoiding the Poipet Scams

Here is the scam I mentioned earlier: the Official Government Bus trick at Poipet. Touts will approach you near the border and insist that the main immigration office is closed or that you must take a specific shuttle to a secondary office. This secondary office is actually a travel agency that will charge you $60 USD for a $30 USD visa. They are very convincing. They might even wear uniforms that look official. Dont fall for it.

Just keep walking toward the actual immigration building. Lets be honest, border officers are rarely in a rush to help you avoid scams. You have to be your own advocate. Official border crossing fees are zero for visa-exempt travelers, but you might be asked for a 100-200 THB (about $3 to $6 USD) administrative fee for a stamp. While not technically legal, most travelers pay it to avoid being sent to the back of the line. It is a small price for sanity in a high-stress environment.

Choosing Your Overland Route

Via Cambodia (The Fast Track)

• Mostly flat, paved roads; significantly smoother than the northern route
• 18-24 hours from Ho Chi Minh City to Bangkok
• $30 USD for Cambodia Visa on Arrival plus Thai exemption
• Social, backpacker-heavy, and efficient but can feel like a tourist conveyor belt

Via Laos (The Scenic Route)

• Mountainous, winding roads; high chance of motion sickness
• 36-48 hours from Hanoi to Bangkok
• $40-50 USD for Laos Visa on Arrival depending on nationality
• Intrepid, quiet, and stunningly beautiful; best for those with extra time

The Border Run: Minh's 24-Hour Marathon

Minh, a 24-year-old freelance designer in Ho Chi Minh City, decided to surprise his friends in Bangkok for Songkran. Wanting to save money for the festival, he booked a $38 USD bus ticket instead of a $210 USD flight. He felt confident and prepared.

At the Moc Bai border, the friction started. He realized he had only kept Vietnamese Dong and his credit card, forgetting that the Cambodian visa required exactly $30 USD in cash. He had to pay a local fixer an exorbitant exchange rate just to get the dollars needed.

The breakthrough came at a dusty rest stop near Phnom Penh. Instead of stressing about the delay, he shared some dried squid with a fellow traveler who showed him how to pre-fill the mandatory TDAC form for Thailand. This saved him nearly two hours of queuing at the Poipet border.

Minh arrived in Bangkok 22 hours later. He was exhausted and covered in dust, but he had saved over $170 USD - enough to pay for his entire week's accommodation. He learned that land travel is 10% logistics and 90% having the right cash and a bit of patience.
