Every year, Thailand’s Department of National Parks (DNP) temporarily closes a number of visitor attractions. The closures at some of Thailand’s national parks are primarily for safety reasons or to allow for the rest and recovery of specific sites. Attractions affected include popular dive zones, waterfalls, mountains and caves. The timing of the closures mainly coincides with the May-October rainy season although there are some regional variations with the dates. Heavy rain can result in dangerous conditions on hiking trails and at beauty spots. And at sea, some national marine parks are subject to strong winds and big waves which can make conditions hazardous for small boats and unsuitable for diving.
When are parks closed?
The exact dates and locations where access is restricted at national parks can vary from year to year. On Thailand’s Andaman Coast, the closures usually take place from May-October. On the opposite Gulf Coast, the period of closures tend to be from November to mid-December. It’s also important to note that the closures don’t apply to all national parks and there are still many popular natural attractions that can be visited all year round.

*Maya Bay, Phi Phi Islands
Maya Bay on Phi Phi Leh is famous as being one of the locations for the Leonardo DiCaprio movie, ‘The Beach’. Thai authorities restricted access to Maya Bay in 2018 to allow much needed respite for the coral reefs and marine life found in the area. The closure was extended a number of times through until 1 January 2022.
Tourists and boat operators visiting Maya Bay will now be subject to tighter regulations with a reduction in the number of daily visitors allowed.
