Thailand Travel Advisory: Adjustments to Train and Bus Routes in Affected Border Provinces as Security Concerns Rise Along Thailand-Cambodia Border

Published on December 12, 2025

Thailand, a country known for its stunning landscapes, rich history, and vibrant tourism industry, has implemented heightened security measures across its eastern and northeastern provinces due to ongoing developments along the Thailand–Cambodia border. Travel and tourism activities across Thailand remain largely unaffected by these security measures, but visitors heading to certain regions should be aware of travel adjustments and follow the latest updates from local authorities. The safety of visitors is a top priority, and authorities continue to ensure a smooth travel experience for tourists while maintaining public safety in the affected areas.

As of December 2025, the Tourism Authority of Thailand (TAT) has issued a travel advisory regarding enhanced border security in provinces along the Thai–Cambodian border. Despite some checkpoints being closed, Thailand continues to welcome tourists across its major destinations, including Bangkok, Chiang Mai, Phuket, Samui, Krabi, Pattaya, and Ayutthaya. The travel advisory serves as a proactive measure to keep travelers informed and guide them to safer routes, ensuring that the country remains a top tourist destination in Southeast Asia.

What the Travel Advisory Means for Travelers

• Enhanced Security in Seven Border Provinces: The Thai government has placed special attention on seven provinces near the Cambodia border, including Ubon Ratchathani, Si Sa Ket, Surin, Buri Ram, Sa Kaeo, Chanthaburi, and Trat. Martial law has been enforced in some districts, and a curfew has been imposed in certain areas to maintain public order.
• Martial Law and Curfew Zones: Specific districts, such as Mueang Chanthaburi, Tha Mai, and Aranyaprathet, are under martial law, which means there are additional security measures in place to control movement. Furthermore, a curfew is in effect in parts of Sa Kaeo province, restricting residents and visitors from leaving their homes between 7 PM and 5 AM.
• Traffic Adjustments: Rail services and bus routes near the affected areas have been temporarily adjusted. Train services that previously ran to Ban Khlong Luek, a key border checkpoint, have been suspended. For safety reasons, passengers traveling to Ubon Ratchathani or Kantharalak should use alternative boarding points.
• Travel Safe with Updated Routes: Travelers are advised to avoid certain routes, particularly those leading to restricted border zones. Areas such as Khao Phra Wihan National Park and Prasat Ta Muen Thom in Si Sa Ket remain off-limits. Visitors are encouraged to follow the advice of local authorities to ensure their safety while traveling.

Thailand’s Major Tourist Destinations Remain Open

Despite the temporary disruptions in some border regions, Thailand’s most popular tourist spots remain unaffected and are operating as usual.
