While there are no restrictions in place, visitors to Thailand can roam freely as long as they can show proof of vaccination or pre-departure COVID test. Fully vaccinated visitors are required to either print out or show a digital copy of their proof of vaccination. For non-vaccinated travelers, it is mandatory for a pre-departure COVID test within 72 hours with an RT-PCT test or a professional ATK (RAT) antigen test, with test results showing negative/non-reactive. Unvaccinated children must undergo a pre-departure COVID-testing while traveling with an unvaccinated adult.
