No. All seven Thailand-Cambodia land borders have been closed since June 2025, and there is no confirmed reopening date in 2026. Here is what that means for US travelers, why the old Poipet route no longer runs, and how to plan your trip around it.

No. All seven Thailand-Cambodia land borders have been closed since June 2025, and they remain closed in 2026 with no confirmed reopening date. You cannot walk or drive across from Thailand into Cambodia on any visa right now — that includes the Poipet crossing on the Bangkok-to-Siem Reap road and Cham Yeam near the coast. This is a border closure, not a problem with your eVisa: the visa is perfectly valid, there is just no open Thai crossing to present it at. If your trip pairs the two countries, connect them by air. Bangkok to Siem Reap, Phnom Penh, or Sihanoukville are all short, frequent flights, and your Cambodia eVisa is accepted the moment you land at the Cambodian airport.
If you are reading older guides or message-board threads, you will find a confident, well-worn route: train or bus from Bangkok, cross the land border at Poipet, carry on to Siem Reap and Angkor Wat the same day. For years that was one of the most popular overland trips in Southeast Asia. In 2026 it does not run. Every Thailand-Cambodia land border has been closed since June 2025, and the closure has held steady ever since.
This catches US travelers out because nothing about it is obvious until you are standing at the crossing. Your flights into Thailand are normal, your Cambodia eVisa is approved and sitting in your inbox, and on paper the plan looks fine. The problem is purely the border itself — it is physically shut to overland tourist traffic, so there is nowhere to present the visa even though the document is valid. Plan around the old map and you can lose a day, a connection, or the whole leg of your trip.
When the border closed in June 2025, it closed in full. This was not a single checkpoint going dark while others stayed open — all seven of the official Thailand-Cambodia land crossings shut to ordinary tourist traffic at the same time. If your route depended on any one of them, it depended on a crossing that is currently not operating for travelers entering Cambodia by land.
Two of them are the ones US travelers almost always have in mind. Poipet, opposite Aranyaprathet, is the big one — it is the crossing on the Bangkok-to-Siem Reap road, the gateway that carried the backpacker overland route for two decades. Cham Yeam, near the coast opposite Hat Lek, is the second most common, used by travelers running the Bangkok-to-Sihanoukville or Koh Kong beach route. Both are closed. The remaining crossings are smaller and more regional, but the rule is uniform: none of them are open for tourist land entry into Cambodia in 2026.

The closure traces back to a border dispute between Thailand and Cambodia that escalated in mid-2025. Rather than keep a partial flow of traffic running through contested points, both sides sealed the land crossings to ordinary travelers. The practical effect for tourists is straightforward even if the politics are not: the gates are shut, and they have stayed shut for a full year as of this writing.
The honest planning answer is that there is no confirmed reopening date. The situation has been static for around twelve months, talk of reopening has come and gone without a firm change on the ground, and a date that is floated one month can slip the next. For trip planning that means one thing: do not build an itinerary that assumes the border reopens partway through your travels. If it reopens while you are in the region, that is a bonus you can use — but it is not something to plan around.

Se você precisa de um Cartão e-Arrival do Camboja (e um eVisa do Camboja) durante uma escala no Aeroporto Internacional Techo (KTI) ou Siem Reap (SAI) depende de uma pergunta: você vai cruzar a linha de imigração? Aqui está o regulamento exato de 2026 para transferências airside, passagens separadas e voos domésticos.
As regras de fronteira do Camboja mudaram significativamente para 2026: Phnom Penh abriu o Aeroporto Internacional Techo (KTI), selos de papel foram substituídos pelo V-Pass digital, e todas as passagens terrestres entre Tailândia e Camboja permanecem fechadas. Aqui está a lista de verificação completa de entrada de 2026 para viajantes canadenses.
Cidadãos britânicos que viajam para o Camboja em 2026 precisam tanto de um visto cambojano válido quanto de um Cartão e-Arrival digital do Camboja (CeA). Aqui está como os portadores de passaporte do Reino Unido escolhem entre o eVisa de Turista (Classe T), eVisa Ordinário (Classe E) e Visto na Chegada no Aeroporto Techo (KTI) ou Siem Reap (SAI).

The good news is that pairing Thailand and Cambodia is still completely doable in 2026 — you just connect them in the air rather than on the ground. The flights are short, frequent, and cheap by long-haul standards, and they drop you straight into a Cambodian airport where your eVisa is accepted on arrival. For most US itineraries, the air leg actually saves time over the old land route, which involved a long road transfer and a slow crossing on foot.
In practice, here is how the common pairings work now. Bangkok to Siem Reap is the direct replacement for the old Poipet overland run — about an hour in the air, landing at Siem Reap-Angkor International (SAI), a short drive from the temples. Bangkok to Phnom Penh lands you at Techo International (KTI), the new capital airport. Bangkok to Sihanoukville reaches Sihanouk International (KOS) on the south coast, the air version of the old Cham Yeam beach route. In every case your eVisa is checked the moment you land, and you skip the land border entirely.

If overland travel is the whole point of your trip — and for a lot of Americans doing the Indochina loop, it is — you have not lost it. The Thailand land legs are off the table, but the Vietnam and Laos crossings remain open and eVisa-eligible, so the classic loop still runs by land everywhere except the Thai border. You build the route so that the Thailand portion is flown and the rest is overland.
Do Vietnã, as principais travessias usadas por viajantes da rota do Mekong aceitam o eVisa, incluindo Bavet na estrada de Ho Chi Minh City e a travessia fluvial de Kaam Samnor na rota de barco rápido do Mekong. Essa é a perna terrestre ou fluvial de Saigon a Phnom Penh, e funciona com eVisa em 2026. Do Laos, a travessia de Trapeang Kriel no norte — a rota padrão para baixo a partir do sul do Laos e das 4.000 Ilhas — também é elegível para eVisa. Um circuito que vai do Vietnã ao Camboja ao Laos, ou qualquer subconjunto dele, está totalmente aberto por terra.

The clean version, for any American planning a 2026 trip: the Thailand-Cambodia land border is closed — all seven crossings, since June 2025, with no confirmed reopening date. You cannot cross overland from Thailand on any visa, so connect the two countries by air. Your eVisa is unaffected and is accepted at all three Cambodian airports the moment you land. If you want an overland leg, run it through Vietnam or Laos at a confirmed eVisa-eligible crossing instead. Fly the Thailand portion, and the rest of the loop is yours.
