In March 2021, Thai authorities set out a roadmap to open up Thailand to fully vaccinated travellers without the need for quarantine. The plan will take place in phases starting with Phuket before being rolled out to other destinations including Chiang Mai, Ko Samui, Krabi and Pattaya.

Analysis
The Thai authorities have a difficult balancing act. While there is an economic need to reopen the crucial tourist industry, there is also a need for it to be done in as safe a way as possible. And while this proposed roadmap provides a better idea of a timeline, there are still some points awaiting clarification.
The details on this page should be viewed as a guide rather than a guarantee. The timeline depends on the success of the vaccine rollout in Thailand and the Covid-19 situation in Thailand and other countries.
There will almost certainly be some changes to the details of the roadmap over the coming weeks and months. When more details are confirmed, we will add updates on our travel advice page.
