How Far Is Thailand from Vietnam? Everything You Need to Know Before You Go

If you’re planning a Southeast Asia trip, Vietnam and Thailand are likely on your radar. Although they are close neighbors, the actual distance and best travel method depend on your departure and destination cities. This guide breaks down the distance by air, land, and other travel options—making your trip planning easier than ever.

Thailand and Vietnam on the Map: Are They Close?

Thailand and Vietnam are located in mainland Southeast Asia, with Laos and Cambodia lying between them. On the map, Vietnam hugs the eastern coast of the Indochinese Peninsula, while Thailand rests more centrally to the west.

Although they don’t share a direct border, the shortest aerial distance is around 150 kilometers (93 miles) at the closest points. For city-to-city travel, the distance increases significantly. For instance:

• Thailand private tours

• Hanoi to Bangkok: ~990 km (~615 miles) by air
• Ho Chi Minh City to Bangkok: ~740 km (~460 miles) by air

Land travel involves passing through Laos or Cambodia, resulting in longer, slower routes compared to air travel.

Taking the Train: A Scenic Overland Option

No direct train connects Vietnam and Thailand, but you can travel overland using a combination of trains and buses through Cambodia or Laos. Though slower, this journey rewards travelers with scenic views and cultural experiences.

Via Laos (Hanoi to Bangkok or Chiang Mai)

Start in Hanoi, travel to the Laotian border, and continue to Vientiane. From there, cross into Thailand via the Friendship Bridge and board a train from Nong Khai to Bangkok or Chiang Mai.

Travel time: 30–36 hours, depending on transfers and border delays.

Via Cambodia (Ho Chi Minh City to Bangkok)

Take a bus from Ho Chi Minh City to Phnom Penh, then another to the Thai border at Poipet. After crossing into Thailand, board a local train to Bangkok.

Travel time: 24–30 hours.

By Road: A Rewarding Journey for Adventurers

Though there’s no direct land border, overland routes via Cambodia or Laos are popular among backpackers and motorbike riders.

Via Laos

Start in Hanoi and cross through border gates like Lao Bao or Nam Can. Travel through Laos via Savannakhet or Vientiane, and enter Thailand through the Friendship Bridge. Expect 3 to 5 days depending on your pace.

Via Cambodia

Ride from Ho Chi Minh City through the Moc Bai border, then pass Phnom Penh and Poipet before entering Thailand at Aranyaprathet. This route also takes 3 to 5 days.

Important: Riders should carry an international driving permit, vehicle registration, and cross-border permits. Motorbikes under 175cc may face restrictions at some crossings.

Traveling by Boat: Is It Possible?

Technically, yes—but not directly or practically. No ferry or international boat service connects Vietnam and Thailand. However, scenic segments may involve boats, especially on the Mekong River.

For example, travelers can take a slow boat from Luang Prabang to Chiang Khong in northern Thailand after crossing into Laos. While scenic, this option is indirect and time-consuming.

Which Travel Option Is Right for You?

• Fly: Ideal for speed, comfort, and affordability.
• Train + Bus: Perfect for scenic and budget travel.
• Motorbike or Car: Great for freedom and adventure.
• Boat: A scenic detour—not a border-crossing method.
