There is some crime and social unrest across Thailand, including a separatist insurgency in the far southern provinces. However, you’ll almost never find conflict in tourist areas in other provinces. Furthermore, Thailand is rated as one of the least dangerous countries in Asia.
Still, you should be aware of your surroundings whenever you’re traveling in an unfamiliar area, as tourists are prime targets for petty thieves and scammers. Be wary of too-friendly strangers and stick with reputable tours and transportation services. Additionally, large-scale protests over political and social issues can affect major cities, including those frequented by travelers. You don’t necessarily have to cancel your travel plans if there are ongoing demonstrations but be sure to stay away from any large gatherings.
Visit the U.S. Department of State website for up-to-date information on travel advisory levels and safety information for travelers to Thailand.
All U.S. travelers should enroll in the Smart Traveler Enrollment Program (STEP), a free service offered to U.S. citizens traveling and living abroad. Enrolling in this program allows you to receive important information from the Embassy as well as helps the Embassy contact you in an emergency.
