Samui Plus (Samui+), Thailand’s next initiative to revive its ailing tourism industry, has officially (and quietly) taken off.  Just like its sister program Phuket Sandbox, which launched on 1 July, Samui+ is aimed at welcoming back international holiday-makers to the popular beach destination. 

Samui+ kicked off on 15 July, and pretty much follows the same rules mandated by Phuket Sandbox, mainly that all tourists coming to the island should have gotten the required doses of COVID-19 vaccines and complete a looser form of “quarantine” upon arrival. We can say, however, that the Samui + program is a bit more complicated than its predecessor. 

Here’s all you need to know if you’re planning a sun-kissed vacay in Koh Samui.

What is Samui+?

As mentioned earlier, this latest program, like Phuket Sandbox, is designed to rejuvenate Thailand’s tourism industry. Fully vaccinated visitors are welcome to holiday on Koh Samui but on several conditions and given that they complete minimal quarantine requirements.

Samui+ also covers the reopening of nearby popular destinations, namely Koh Tao and Kho Pha-ngan, to tourists.

Who is eligible for the Samui + initiative?

  • Tourists aged 18 and more who:
    • Have been staying in a Center for COVID-19 Situation Administration (CCSA)-approved country for at least 21 days (see list below) prior to arriving in Samui.

* So far, these include AstraZeneca, Sinovac, Johnson & Johnson, Moderna, Sinopharm, and Pfizer.

  • Tourists aged 17 and below don’t have to be vaccinated, but need to test negative for COVID-19 no longer than 72 hours before departure.
  • A Thai national or expatriate who is returning from overseas and has been in a CCSA-approved country for 21 days or more.

What do you need to do once you land in Samui

After completing the paperwork and—of course—going through immigration and customs procedures, you would have to:

  • Download and activate the mobile alert apps specified for Koh Samui.
  • Transit directly and immediately to the hotel you have booked, where you need to undergo an “area quarantine” from days 1 to 3. This means that you need to stay in your hotel and enjoy designated areas within the premises.
  • From days 4 to 7, you can travel within a specified “sealed route” within Koh Samui.
  • You can finally visit surrounding destinations, specifically Koh Tao and Koh Pha-ngan, on days 8 to 14.

After completing 14 days on the island, you are allowed to visit other destinations in the country.

Please note that if you are staying in the island for less than 14 days, you will have to leave Koh Samui on a direct international flight, or take a dedicated Bangkok Airways flight to Suvarnabhumi Airport and then immediately depart on an international flight.
