Thailand National Parks Closed In The Rainy Season

• Conditions during tropical monsoon rains can make travel within national parks difficult and hazardous. Weather conditions can change very quickly. Fog and low clouds tend to hang low over the landscape. Cliffs may collapse under their own weight when the soil underlying the sandstone cap is eroded by heavy rain. Heavy rains can also cause landslides and flash floods in the streams which flow down the mountain slope.
• For safety reasons, specific areas within the national parks on the following list issued by the National Park, Wildlife and Plant Conservation Department will be closed from the date specified until the end of the southwest monsoon season. This also provides a much-needed break from tourism activity and allows the natural environment, flora and fauna to revive and regenerate.

Marine National Parks

• All areas within the Mu Ko Similan and Mu Ko Surin marine national parks will be closed to tourist traffic from 16 May through to 15 November. Mu Ko Rok Nok-Nai and Hin Muang-Hin Deang Rock in Mu Ko Lanta Marine National Park and the islands of Mu Ko Adang-Rawi in Tarutao Marine National Park will also be closed during the same period.
