Thailand has imposed strict daily visitor limits on several ecologically sensitive islands and marine parks. The caps restrict access to protect coral reefs and wildlife from overtourism damage. Operators face mandatory pre-registration and quotas enforced at entry points.
Key locations include the Similan Islands limited to 3,800 visitors per day and Koh Phi Phi Leh capped at 2,500. Surin Islands allow 2,000 daily entrants while smaller sites enforce lower thresholds. The system requires tour companies to secure slots through a centralized government platform.
Authorities cite severe coral degradation and marine life disruption as primary drivers. Some reefs experienced up to 80 percent bleaching in recent surveys linked to excessive human activity. Anchor damage and plastic waste accumulation further threatened protected habitats.
The Tourism Authority of Thailand developed the policy with marine biologists and local stakeholders. Implementation began this season with phased rollout across 12 national park areas. Non-compliant operators risk fines exceeding 500,000 baht and operating suspensions.
Alternative destinations receive promoted itineraries to redistribute visitor flows. Nearby mainland sites and less-visited islands gain marketing support. Low-impact certified operators receive priority quota allocations.
Enforcement combines on-site ranger checks with real-time tracking technology. Satellite monitoring and boat registration ensure compliance. Officials report initial adherence rates above 90 percent during pilot phases.
Similar restrictions proved effective at Maya Bay following its multi-year closure. Coral coverage increased significantly during the visitor absence period. Current measures allow ongoing access while preventing irreversible harm.
Travel providers now require confirmed island permits before confirming bookings. Same-day arrivals without reservations face denial at departure piers. The caps apply year-round with potential seasonal adjustments based on environmental data.
Affected nationalities span all visa categories including visa-exempt entries. Group tours and independent travelers must comply equally. Authorities emphasize the limits support sustainable long-term tourism revenue for coastal communities.
