Vietnam Land Border Crossings: Routes to Cambodia, Laos, and China

Vietnam shares land borders with three countries, and crossing overland is a genuinely good way to travel through the region rather than flying between country capitals. Here's what to expect at the main crossings, and how the process works in practice.

Before You Go: Visas and E-Visa Gates

Vietnam's e-visa is accepted at a wide network of entry points nationwide, including dozens of land border gates, but only at the specific gate listed on your application — arriving at a different crossing than the one you registered can mean being turned back. Always double check the current approved gate list when applying, since gate access is occasionally updated. If you're entering Vietnam overland (rather than exiting), apply with the correct border gate selected; if you're leaving Vietnam, your visa's entry/exit points generally don't need to match.

Crossing to Cambodia

The Cambodia–Vietnam border is the busiest of the three and the easiest for tourists, with around ten approved crossings running from the Mekong Delta up into the Central Highlands.

• Moc Bai–Bavet is the main route, connecting Ho Chi Minh City to Phnom Penh. Direct bus companies (Giant Ibis, Mekong Express, Kumho) run this route daily, handling the border stop as part of the ticket — you disembark, walk through Vietnamese exit control, cross to the Cambodian side, clear immigration, and reboard. The whole trip takes around 6 hours.
• Chau Doc–Kaam Samnor is the scenic alternative, a boat crossing along the Mekong River connecting Chau Doc in the Mekong Delta to Phnom Penh, popular with travelers doing a slower Mekong Delta route.
• Cambodia issues visas on arrival for most nationalities at land borders, but it's worth applying for a Cambodian e-visa in advance to skip the on-arrival queue and avoid the (fairly common) overcharging attempts at smaller land crossings.

Crossing to Laos

Ten crossings connect Vietnam and Laos along their shared northern-to-central border.

• Cau Treo–Nam Phao, near Vinh, is the most used crossing for travelers heading to Vientiane or onward into northern Laos, with direct overnight buses from Hanoi.
• Lao Bao–Dansavanh, near Dong Ha in central Vietnam, connects to Savannakhet and is a common route for travelers combining Hue or Hoi An with southern Laos.
• Laos offers visas on arrival for most nationalities at these crossings, payable in USD; bring passport photos and small bills, since change isn't always available.
• Land crossings into Laos tend to be quieter and slower-paced than the Cambodian border — fewer buses per day, so check schedules in advance rather than turning up and hoping.

Crossing to China

Seven crossings link Vietnam's northern provinces to China, including two rail crossings, and this is the most bureaucratically demanding of the three borders.

• Lao Cai–Hekou connects Sapa/Lao Cai to Yunnan province, reachable from Hanoi by the well-known overnight train to Lao Cai, then a short trip to the border itself.
• Huu Nghi (Friendship Pass)–Youyi Guan, near Lang Son, is the main road crossing toward Nanning and is the most commonly used route for travelers heading further into China.
• Unlike Cambodia and Laos, China does not offer visas on arrival for most nationalities at these crossings — you need a Chinese visa arranged in advance (or to qualify for one of China's visa-free transit schemes, which have specific conditions). This is the crossing most likely to catch travelers out if they haven't planned ahead.
• Border hours are more restricted than the Cambodia and Laos crossings, and the process is generally slower and more formal.

What to Expect at the Checkpoint

Overland border crossings in this region follow a broadly similar pattern: exit stamp from the country you're leaving, a walk (sometimes several hundred meters) across a no-man's-land zone, then entry processing on the other side. Keep your passport, visa printout or approval letter, and any onward bus ticket accessible rather than buried in a backpack — you'll need to produce them multiple times in a short window.

Bring small USD or the destination country's currency for visa-on-arrival fees (Cambodia, Laos), since card payment isn't available at most land crossings. Unofficial "service fees" at smaller crossings are a known irritation — a polite but firm decline, or going through official channels via your bus company, generally resolves it.

Practical Tips

• Book border-crossing bus tickets through a reputable operator rather than the cheapest option; they handle the paperwork stop smoothly and know the current gate rules.
• Arrive at land borders earlier in the day — some smaller crossings close in the early evening, and processing an overnight bus that arrives at 2am can mean a long wait for the gate to open.
• Keep a passport photo copy and a couple of extra passport photos on hand; they're occasionally requested for on-arrival visas.
• Double-check current border gate and visa rules close to your travel date — these do change, and forum threads from a year or two ago aren't a reliable substitute for checking an official source before you cross.

Crossing overland adds a day of logistics compared to flying, but it's a genuinely good way to see how Vietnam connects to its neighbors, and land border towns often make for interesting, rarely-visited stops in their own right.
