Tips for Visiting Thailand’s National Parks

Entrance Fees:
Visiting Thailand’s national parks requires an entrance fee which varies depending on the park and is sometimes included in tour packages. Always check whether the fee is covered in your booking or if you need to pay at the entrance. Fees are prominently displayed in both Thai and English.

Seasonal Closures:
Thailand’s national parks often close during the low or rainy season to protect visitors and allow the environment to recover. Some trails and caves become hazardous in wet weather, making closures necessary. Before planning your visit, check with local sources like hotels or tour operators for the latest opening and closing dates.

Busy Periods:
National parks are popular weekend and holiday destinations for locals. Parks like Doi Inthanon, especially during the New Year holiday, can get crowded, leading to busy trails and traffic. To avoid the crowds, consider visiting on weekdays or outside of major holidays.

Responsible Travel:
To protect the environment, single-use plastics are banned in all Thai national parks. In 2021, Thailand implemented stricter regulations to safeguard its coral reefs. Sunscreens containing harmful chemicals like Oxybenzone, Octinoxate, 4-methylbenzylidene Camphor, and Butylparaben are prohibited in all national parks. Visitors are encouraged to use reef-safe sunscreens made from mineral-based products like zinc oxide to avoid damaging the delicate marine ecosystems.
