BANGKOK – In 2025, Thailand continues its commitment to environmental conservation by implementing seasonal closures of several popular islands. These measures are designed to allow natural ecosystems to recover from the impacts of tourism and to ensure visitor safety during the monsoon season. 

Islands Temporarily Closed in 2025

Similan and Surin Islands
Located in the Andaman Sea, the Similan and Surin Islands are closed to tourists from May 16 to October 14. This annual closure coincides with the monsoon season, aiming to protect marine life and coral reefs from damage due to rough seas and increased human activity.

Maya Bay, Phi Phi Leh
Famed for its appearance in the film “The Beach,” Maya Bay will be closed from August 1 to September 30. The closure allows the bay’s ecosystem to recover from the stresses of tourism and ensures safety during the monsoon’s rough sea conditions.

Koh Kradan, Koh Mook, Koh Waen, and Koh Chuek
These islands in the Trang province are closed from June 1 to September 30. The closure facilitates ecological restoration and addresses safety concerns during the monsoon season.

Post-Closure Tourist Management

To manage tourist influx and protect natural resources, Thailand is introducing new measures:

• E-Ticketing System: Starting October 2025, visitors to six marine national parks, including the Phi Phi Islands, must obtain electronic tickets. This system requires passport information and aims to regulate visitor numbers.
• Digital Travel Authorization Card (TDAC): Implemented in April 2025, all foreign visitors must complete the TDAC online at least 72 hours before arrival. This replaces the paper-based TM6 arrival card, streamlining immigration and enhancing security.

Balancing Tourism and Conservation

Thailand’s approach reflects a balance between promoting tourism and preserving its natural heritage. While these closures may inconvenience some travelers, they are crucial for ensuring the long-term sustainability of the country’s renowned island destinations. (zai)
