タイ―カンボジア間の陸上国境がすべて閉鎖したまま現在、バイベットはベトナムからカンボジアへの主要な陸上ルートとなっています。ホーチミン市から6時間、印刷したeVisa1枚、e-Arrivalカード不要 ― 2026年に米国市民が実際どのように通過するかを解説します。

Cross at Moc Bai (Vietnam) into Bavet (Cambodia) on Highway 1, the main overland route from Ho Chi Minh City to Phnom Penh. Apply for your Cambodia eVisa before you board — $80 USD all-in for the Tourist eVisa, approved in 3–5 days, delivered as a printable PDF. Bring a US passport with at least 6 months validity and one blank page, plus two printed color copies of the eVisa. The bus ride is 4 to 6 hours to the border and 2 to 3 hours on to Phnom Penh. You do NOT need the e-Arrival Card for a land crossing — it is for air arrivals only. Visa on arrival at Bavet exists but is unreliable, so do not count on it.
Until mid-2025, an American planning an Indochina trip had three overland ways into Cambodia: from Thailand at Poipet, from Vietnam at Bavet, or from Laos in the far north. Since June 2025 the Thailand option has been off the table — all seven Thai–Cambodian land crossings are closed with no reopening on the calendar. That has quietly made Bavet the main overland route into Cambodia for the entire backpacker and family-travel crowd flying out of LAX, SFO, and JFK toward Ho Chi Minh City.
The crossing itself has run smoothly throughout. Bavet on the Cambodian side, Moc Bai on the Vietnamese side, Highway 1 connecting Saigon to Phnom Penh. Four to six hours on the bus to the border, another two to three hours to the Cambodian capital. If you are planning both legs of the trip, our Cambodia and Vietnam visa combo guide for Americans covers the two-visa sequencing, and the dedicated Bavet eVisa walkthrough drills into the desk-by-desk detail.
This article is the field-tested version: how the bus journey actually plays out for a US passport holder in 2026, which operators are reliable, where Americans most often trip up, and what to do if something goes sideways at the border. The rhythm of the crossing has changed less than you would expect over the last few years — but the visa policy around it has changed more than most travel blogs have caught up with.
Four operators run the Ho Chi Minh City to Phnom Penh route in 2026. Two are safe picks for Americans, two are cheaper but rougher around the edges. None are bad, exactly — but at the border, the operator’s relationship with Cambodian Immigration is the variable that decides whether your bus waits ten minutes or ninety. Here is the honest side by side.
Mekong Express is the operator most Americans end up on, and there is a reason — they have run the route since the early 2000s, the fleet is genuinely comfortable, and the on-board attendant collects every passenger’s passport on the Vietnam side and walks the stack through both immigration desks. You stay on the bus for the Vietnamese exit, step off briefly to walk through Cambodian Immigration on foot, then reboard. The whole crossing usually clocks in at 45 to 75 minutes. Departures run from the Pham Ngu Lao office in District 1, Saigon, multiple times daily. Book online or at the office the day before.

Giant Ibis is the other favorite among US travelers, marketed slightly more toward the Western backpacker market and reliably booked solid in peak season (November through February). Same general experience as Mekong Express — the passport-runner system, reclining seats, AC, wifi — at roughly the same price. If Mekong Express is sold out for your date, Giant Ibis is the obvious second choice. They run from a small office near Pham Ngu Lao, departing early to land you in Phnom Penh by mid-afternoon. Both operators accept card payment online; the cheaper operators usually want cash at the office.

Most Mekong Express and Giant Ibis services leave Saigon between 6:30am and 8:30am — the early start is deliberate, because Cambodian Immigration at Bavet processes faster before mid-afternoon. Aim for a morning departure, not an overnight; the few overnight services that exist make the crossing slower and cost you a sleep cycle in the process.
The first leg is roughly two and a half hours from central Saigon to the Moc Bai border, through the southern Vietnamese countryside on Highway 1. The bus stops once at a rest area for about twenty minutes — restroom, instant coffee, a bowl of pho if you skipped breakfast. Pay in Vietnamese dong (keep small notes — VND 50,000 is plenty for coffee), since the rest area does not reliably accept cards.
At Moc Bai, the bus pulls up at the Vietnamese exit gate. On Mekong Express and Giant Ibis, the attendant collects every passenger’s passport and the small departure card you filled in on the bus. You stay seated. The attendant returns with stamped passports ten to twenty minutes later — your Vietnamese exit stamp, with no queue for you. On the cheaper operators (Kumho Samco, Sapaco), you sometimes have to step off and queue at the desk yourself; this is the slowest, most error-prone part of the whole trip.
Across the short stretch of no-man’s-land — a two-to-three-minute walk or shuttle — you reach Bavet on the Cambodian side. Here you do get off the bus. Hand the Cambodian Immigration officer your printed eVisa PDF (one A4 copy is fine, two is safer) and your passport. The officer reviews the eVisa, stamps the passport with the entry stamp showing your 30-day stay window, and waves you through. There is no card to fill in for land arrivals — the desk handles entry directly. Cambodian-side processing is usually 15 to 30 minutes per bus.
カンボジア出入境管理局の敷地でバスに再乗車してください。バベットからプノンペンまでの残りの区間はMostly decentな2車線的高速道路で約95キロメートル、都心への交通状況により2〜3時間です。最後にあと一回休憩があり、たいてい信頼できるクメール料理があり、小額の米ドル紙幣を受け付けています——1ドル、5ドル、10ドル札を何枚か用意しておきましょう。小規模な露天商しベルでもカンボジアでは米ドルが通用します。プノンペンへの到着は通常、中心部に近い小さなターミナルです。 Tuk-tuk(トゥクトゥク)とPassAppの配車がどこでもにあります。

カンボジアはバベットで入国時にビザを取得可能ですが、問題は「技術的には」という点です。実際には、税関ブースは物理的なビザ스티ッカーが品切れになることが珍しくありません——半日も品切れになることもあれば、3日連続で品切れになることもあります。スティッカーが切れている場合、税関ブースはあなたを追い返したり、新鮮なバッチを待つ間数時間も側部屋に待たせたり、最悪の場合、ビザなしでベトナムに戻るよう指示し、戻りの道も容易ではありません。これらのシナリオは理論上のものではなく,每月発生しています。アメリカ合衆国市民向けカンボジアeVisaはこうした問題全体を回避できます——すでに承認された状態でバベットに到着します。
Tourist eVisaは$80 USD(全て込み)で、3〜5日で承認され、メールで印刷可能なPDFとして届きます。フライトの予約もホテルの予約も銀行明細も不要です。アメリカ合衆国を出発する前にオンラインで申請するか、最低でもサイゴン出発日の1週間前に申請して、バスに乗る前に承認状が受信箱にあるようにしましょう。出張で旅行する場合は、 Business eVisaは同じ3営業日(土日祝 제외)で$90 USD(全て込み)です。数分でどちらでも申請できます。
eVisaのPDFをカラーで2部刷って、一般的なレターサイズまたはA4サイズの紙に印刷してください。1部を税関で提出し、もう1부는デイパックの一番下にバックアップとして入れておいてください。カンボジア出入境管理局のバベットではQRコードを読み取りますが、印刷物が正式な書類となります——手机画面は陸路的国境では確実に受け入れられるとは限りません,所以必ず紙を持ってきてください。パスポートは通過日から少なくとも6ヶ月以上の有効期限があり、入り口のスタンプ用に少なくとも1枚の空白ページが必要です。
たとえ陸路的国境であっても、少額の米ドル現金を準備しておきましょう——2006年以降の発行者で新品同様の損傷のない紙幣で50〜100ドル程度を言ってください。休憩立ち寄り、プノンペンのトゥクトゥク、そして初夜の雑費に使えます。もう一つアメリカ人が见落とすことの多い点:たとえ陸路的国境であっても、税関の役人が次の行き先を要求することがあります。ベトナム国境での出国旅行の証明に関する当店の注记には、何を準備すべきかが詳しく記載されています。

過去数年間に私たちのデスクを通じた多くのアメリカ人通過者のため、4つの間違いが繰り返し発生しています致命的ではありません——最悪の場合でも通常は数時間の延迟ですが、いずれも回避可能です。
One more point on timing: the border is open 6:00am to 10:00pm, but Cambodian Immigration’s afternoon shift is reliably slower than the morning shift. Buses that hit Bavet after 4pm regularly wait an extra 45 minutes. The morning Saigon departures from Mekong Express and Giant Ibis are scheduled around this — they aim to land you at Bavet around 11am to 1pm, which is the sweet spot.

Going back the other way is structurally similar, but the visa logistics flip. The Cambodian exit stamp is free and instant. The Vietnamese entry is what now needs paperwork, and the single-entry trap is where Americans most often get stuck.
If your Vietnam e-Visa was single entry and you have already used it, you cannot re-enter Vietnam without applying again. If your plan is Vietnam, then Cambodia, then back into Vietnam — for instance, flying home out of Hanoi — buy the multi-entry Vietnam e-Visa up front before you leave the United States rather than scrambling for a fresh one in Phnom Penh. On the Cambodia side, remember the eVisa you used to enter at Bavet is single entry; if you leave Cambodia and want to come back, that is a fresh eVisa.
Both Mekong Express and Giant Ibis run the return journey from Phnom Penh with the same passport-runner system in reverse. Buses depart Phnom Penh between 6:30am and 8:30am, aim to clear Bavet by 11am to 1pm, and land in Saigon around 3pm to 5pm. The same advice applies: morning departure, paper visa, blank passport page, USD cash buffer, stay with the bus group.
If you are flying out of Saigon the same day, give yourself at least four hours of buffer between the bus arrival and your international departure. Traffic between the central bus terminal and Tan Son Nhat (SGN) can be brutal at peak — 25 minutes off-peak, 90 minutes in heavy traffic. A ride-share or tuk-tuk to the airport is straightforward but not fast.
If you are crossing in the next month, it is worth a five-minute read of the State Department’s Cambodia and Vietnam pages for the current safety picture — particularly during the wet season (May to October), when occasional flooding along Highway 1 can slow the journey. And before you assume you need to fill in an arrival card, read our explainer on the e-Arrival Card at land borders versus air: at Bavet you do not need it, but you will for any later flight into Cambodia.
Pack list for the bus: printed eVisa (two copies), passport, $50 to $100 USD in clean small bills, a few hundred thousand VND for the Vietnamese rest stop, snacks, a water bottle, a downloaded film or a paperback for the long stretch, a light layer for over-aggressive bus AC, and a US-to-Southeast-Asia plug adapter for charging at the Phnom Penh end. The bus has USB ports, but they are slow.
Next steps and related reading for US travelers: apply for your Cambodia eVisa when you are ready to lodge, bookmark our Cambodia visa hub for United States citizens as the single canonical reference, line up your two-country paperwork with the Cambodia and Vietnam visa combo guide, and confirm what to carry with the proof of onward travel note before you board.
