Vietnam shares land borders with three countries and the right crossing depends on your route, your visa, and the day of the week. This widget picks the border that fits your trip — Cambodia, Laos or China — with 2026 hours, fees, e-visa status, and the scam patterns that live at every land crossing.
Crossings are not interchangeable. From HCMC to Cambodia, Mộc Bài is fast and touristy; Bát Cóc via Hà Tiên is a Mekong boat combo that ends you in Kampot; Kaam Samnor is a Mekong river crossing to Phnom Penh. They have different hours, different e-visa acceptance, and different scam levels. The wrong crossing on a Friday at 4 pm means a night in no-man's-land. The widget below matches the country + your preferred crossing to a clean itinerary.
Also covered: the "money gram" agent pattern at land borders (someone offers to "save you the visa fee" by wiring money — it's a scam), the e-visa vs visa-on-arrival reality at each crossing, and the weekend vs weekday queue patterns.
Target country + preferred crossing + group size. We'll tell you hours, total cost, and the one tip.
Each country has different crossings.
"Best by route" picks the easiest for your start city.
Larger groups need pre-booked transport.
Weekend queues can be 2–4× longer.

The one tip that matters

Cambodia: three crossings, three different vibes. Mộc Bài is the workhorse — HCMC → Bavet → Phnom Penh by bus (4–5 hours total), open 7 am – 8 pm daily, e-visa accepted, well-policed. Bát Cóc is the slow boat — Hà Tiên → boat → Kratié via Kampot, 6–8 hours, e-visa accepted at the Cambodian end. Kaam Samnor is a Mekong river port with a small ferry to Phnom Penh — fastest water crossing but only one boat per day and capacity limits.
Laos: two practical crossings. Lào Bảo (Quảng Trị Province) is the standard Huế → Savannakhet route. Open 7 am – 5 pm, e-visa accepted, 5–6 hour total trip. Cầu Treo (Hà Tĩnh) is the central route to Lak Sao / Vientiane — open 7 am – 5 pm, e-visa accepted, longer bus journey (10–12 hours), but it gets you to Vientiane in one push. Nậm Phao (same corridor, alternative gate) is a side route to the Bolikhamxai province.
China: one practical crossing. Hữu Nghị (Lạng Sơn Province) connects to Nanning via the Friendship Pass. Open 7 am – 5 pm (with a lunch break around noon), e-visa accepted for Vietnam side, Chinese visa must be pre-arranged. Closed during major Chinese holidays (Spring Festival, National Day week).
The "money gram" agent pattern. At every Vietnamese land border, a small ring of agents will offer to "save you the visa fee" by wiring money to a relative abroad. The wire is fake, the fee disappears, and you have no visa stamp. Walk past them. The official visa window is 5 metres further on, and the fee is exactly what the embassy says.
E-visa vs visa-on-arrival at each crossing. Vietnam's e-visa (introduced 2017, expanded 2023 to 90 days, multi-entry) is accepted at all major land crossings listed here. Cambodia accepts Vietnam-issued e-visas for most nationalities. Laos accepts e-visas at Lào Bảo, Cầu Treo, and Nậm Phao. China does not accept e-visas — you need a pre-arranged Chinese visa from a consulate before you arrive at Hữu Nghị.
Weekend vs weekday pattern. Friday–Sunday at Mộc Bài means 90-minute queues. Weekdays are 15 minutes. The smaller crossings (Bát Cóc, Cầu Treo) are less affected. Saturday morning at Lào Bảo is the peak of the weekly Vietnamese tour bus to Savannakhet — avoid it.
"Save 50% on your visa by sending money to my cousin in Cambodia." They pocket the wire, you leave with no stamp. The official window is 5 metres further on. Always pay at the official counter.
Drivers and touts insist you need a "health form" or "border exit form" that costs $5–10. The only real form is your visa application. Decline politely and walk to the window.
Touts claim the next bus is full so you'll pay for a private car. The next bus arrives in 20 minutes and has 8 empty seats. Check the schedule yourself at the official window.
At Bát Cóc, a "luggage storage" kiosk charges per bag to hold your suitcase while you take the boat. The bag is fine at the boat dock in plain sight. Don't pay.
Yes — it's the easiest Vietnamese land border, used by hundreds of daily tourists and expats. The Vietnamese side is orderly, the Cambodian side (Bavet) is more chaotic but the bus drops you directly at a reputable Phnom Penh operator. Take the morning bus — it's calmer.
Yes — for most nationalities, an e-visa applied online 3 business days before is the standard pattern. The visa-on-arrival window at Kaam Samnor is theoretically available but unreliable for the boat combo. Apply online at evisa.gov.kh.
No. China does not issue visas at Hữu Nghị. You need either a pre-arranged tourist visa (L), business visa (M), or a 144-hour transit visa if eligible. Apply at the Chinese consulate in HCMC or Hà Nội at least 5 business days before travel.
It happens — especially on Vietnamese public holidays (Tết, Reunification Day). Reputable operators refund or reroute. If you've booked independently and arrive at a closed border, your only options are to wait (some border cafés have basic rooms) or taxi back. Always check holiday calendars in advance.
Border Crossing Guide is a Vietnam Compass standalone tool. It exists because "just take a bus" is incomplete — the choice between Mộc Bài, Bát Cóc, Lào Bảo and Cầu Treo depends on your route, your visa, and the day of the week. The recommender runs in your browser; nothing is sent anywhere.
Limitations. Border hours and visa rules shift occasionally. The widget reflects 2026 conditions; always confirm with the relevant immigration authority before travel.
Data collection. None. This tool is a single HTML file. The recommender runs entirely in your browser — no inputs are sent to any server, logged, or stored.
