Similan and Surin Islands Enforce Five-Month Tourism Ban

Two prominent marine parks in Thailand, Mu Ko Surin and Mu Ko Similan, will close to tourists from May 15 to October 15, 2026, following a directive from the Department of National Parks, Wildlife and Plant Conservation. This five-month closure aims to enhance visitor safety during the monsoon season and allows the natural ecosystem to rejuvenate.

Surasak Anuson, director of Protected Area Regional Office 5 in Nakhon Si Thammarat, confirmed the decision affecting these parks in Phang Nga province. The closure not only addresses seasonal safety concerns but also provides time for environmental recovery. Additionally, officials plan to upgrade park facilities during this period to ensure readiness for the next tourism season starting October 2026.

Siriwat Suebsai, chief of Mu Ko Similan National Park, reported that the Similan Islands contributed over 215 million baht in revenue from more than 400,000 tourists last season, with foreign visitors making up over 90% of this number. The economic boost extends to nearby Phang Nga and Phuket, highlighting the area's significance.

Looking ahead, authorities emphasize strict conservation practices, including tourist limits and safety measures, to maintain the parks' natural beauty and ecological health. These efforts aim to protect Thailand's valuable marine resources for sustainable tourism in the future.

So that's killed all the diving boats.

Doubt they'll be able to keep any boats running for just 7 months a year.

More than 100 million a year in tourist income gone at the stroke of a bureaucrats pen, along with 200,000 tourists.

You think they closed the area for stormy season?

I sort of doubt that, but there's a chance you might be right.

I suppose this will help the eco system develop back to how it should be. Of course, making people unemployed is never good, but then destroying the things that make tourists come won't help. Thailand needs to diversify its industries and pour resources into education.

Don't think it's normallyclosed per se, just think that they chose a time of year when the least boats will go out as many days they literally can't and diving is all about visibilty otherwise what's the point..............christ knows

I remember the Samilan islands being closed for certain parts of the year (typically during the southwest monsoon season from roughly mid-May to mid-October).

The closures applied to diving, snorkelling, overnight stays, and most tourism activities - this is going back 15 years or so.

I'm not sure what the 'change' is here.

There are a lot of issues about excessive tourism in a number of countries. Japan and Spain come to mind. These Islands need to be protected. We visited Similan a number of years ago and saw the distructive activities of tourists. They didn't give a <deleted> about the request to protect the natural habitat. Sorry not sorry to hear this is one area Thailand is making an effort to protect.

As far as I know the Similan Islands are closed to the public every year. This annual closure typically lasts about five months, from mid-May to mid-October.

The closure serves to actively protect the environment, allowing the ecosystem, coral reefs, and wildlife to recover. Additionally, the sea is too dangerous for excursion boats during this time due to the monsoon (rainy season with strong winds and high waves).
