Foreigners who wish to travel to Thailand and are fully-vaccinated can travel to Koh Samui without needing to undergo a quarantine. The Samui Plus plan allows travelers who are not vaccinated to enter and stay in an approved hotel for a reduced number of days.
Following the Phuket Sandbox Plan, travellers can visit Koh Samui under the Samui Plus program, however, they must follow the measures that are mandated by the government. This includes tasking multiple Covid-19 tests on specific dates before being allowed to leave the quarantine hotel and travel to other parts of Thailand. It is important to keep updated with the rules and regulations as they can change at a moment’s notice. To see current news about traveling to Thailand, click here:
