Travel in Thailand during COVID-19 (for Non-Thaïs)
If obviously, it is the vaccinated tourists that Thailand welcomes with the most favorable conditions, it remains possible for non-vaccinated foreigners to come to Thailand but with a strict quarantine on arrival in a dedicated hotel. For vaccinated tourists who want to come to Thailand, conditions have eased over the months. At present time, the majority of foreign tourists are eligible for the Test & Go
program which allows foreign travelers who have been vaccinated to be tested upon arrival in Thailand and after negative results are allowed to travel freely all over the country. For the others, there is the sandbox program
which, in short, requires you to stay a few nights in a restricted geographical area before being allowed to go everywhere in Thailand.
You will find all the details of these entry programs in Thailand on TATNews website.
