Mu Ko Similan, Mu Ko Surin and Mu Ko Lanta national parks will close for five months from today in an annual tradition to let nature rehabilitate itself during the monsoon season.
An announcement on the Facebook account dedicated to the three marine parks said visitors will not be admitted from today until Oct 14 as the recovery begins.
The temporary closure follows the policy of the National Parks, Wildlife and Plant Conservation Department to give the flora and fauna in all parks time to regenerate during the off-peak season for tourists.
Similan and Surin are popular destinations in Phangnga, while Lanta in Krabi is also famous for its clear water and white sand.
Thailand officially entered the rainy season last Friday, the Meteorological Department said.
