Travelers planning to enter Cambodia from Thailand should be aware that land border crossings between Cambodia and Thailand remain closed as of September 2026.
The closure affects travelers planning to cross between the two countries by road, including popular overland routes used by backpackers and independent travelers. The situation remains subject to change, so anyone planning an overland journey should check the latest border information before departure.
Are Cambodia–Thailand Land Borders Open?
No. Cambodia–Thailand land border crossings remain closed to travelers.
This means you should not plan a trip that depends on crossing the border by bus, private car, taxi or on foot. The closure affects the main land routes between the two countries, including the crossings commonly used by travelers heading between Thailand and destinations such as Phnom Penh and Siem Reap.
Travel advice from the Australian government, still current on September 2, 2026, confirms that all land border crossings between Cambodia and Thailand remain closed. The UK Foreign, Commonwealth & Development Office also reports that land borders and crossings between the two countries continue to be suspended.
What Does This Mean for Travelers?
If you are planning a Thailand–Cambodia trip, you should currently treat the two countries as air-connected rather than land-connected for international travel.
For example, a traveler who previously planned to travel overland from Bangkok to Cambodia cannot currently rely on a border crossing to continue the journey.
Instead, consider an alternative itinerary using flights between Thailand and Cambodia. This may require changing the order of your destinations or adding an overnight stay in your departure or arrival city.
Can I Travel from Bangkok to Phnom Penh by Land?
Not while the Cambodia–Thailand land border remains closed.
Cambodia With Me has a dedicated guide to Bangkok to Phnom Penh travel options, but travelers should check the current border status before relying on any overland route.
If the border reopens, road travel may become possible again. Until then, travelers should make alternative arrangements rather than arriving at the border expecting to cross.
What About Bangkok to Siem Reap?
The same restriction applies to travelers planning to travel overland from Bangkok to Siem Reap.
Siem Reap remains one of Cambodia’s most important tourist destinations, but travelers coming from Thailand should currently plan their international connection carefully.
For information about alternative ways of reaching the city, see the Cambodia With Me guides to Bangkok to Siem Reap travel options and how to get to Siem Reap.
What Should Travelers Do Instead?
If Cambodia is part of a larger Thailand trip, the simplest approach is to build your itinerary around an air connection rather than a land crossing.
- Check the current border status before planning an overland route.
- Do not assume that a previously available bus or private-car route is operating.
- Consider flying between Thailand and Cambodia.
- Allow extra time if changing your itinerary or adding an overnight stay.
- Check your airline and travel provider for the latest schedule information before departure.
If you are entering Cambodia by air, you should also make sure you have the required entry documents. Cambodia’s entry requirements can change, so check the latest requirements before traveling.
Is the Border Closure Permanent?
There is currently no confirmed date for a full reopening of the Cambodia–Thailand land border to international travelers.
Because the situation can change at short notice, travelers should not treat the current closure as a permanent arrangement. Check the latest official information shortly before traveling, particularly if your itinerary depends on a land crossing.
What About Cambodia’s Main Tourist Destinations?
The border closure does not mean that international travel to Cambodia as a whole is impossible. Travelers can still plan trips to major destinations such as Siem Reap, Phnom Penh, Kampot and Cambodia’s islands, subject to current travel conditions and transport availability.
If you are planning a trip to Siem Reap, our Siem Reap travel guide covers where to stay, things to do and practical travel information.

Bottom Line
Cambodia–Thailand land borders remain closed to travelers as of September 2026. If your Cambodia itinerary depends on crossing the border by road, you should change your plans and consider an air connection instead.
The situation can change, so check the latest official information before traveling. If the land crossings reopen, overland routes between Thailand and Cambodia may become available again.
