DNP Marine Premium Tier Programme: Visitor Cap and Fee Schedule
THB 800-1,500 per diver per day; visitor cap 4,800 per day (vs prior 8,500+)
The DNP (Department of National Parks Wildlife and Plant Conservation) Marine Premium Tier programme launched Q3 2025 introduces visitor caps, advance-booking gates and fees of THB 800 to 1,500 per diver per day across Mu Ko Similan, Surin and Mu Ko Lanta marine parks. Pre-Premium-Tier, Similan day-trip volume routinely exceeded 8,500 visitors per day in peak season with reef damage rates running 18 to 32 percent of monitored sites; post-Premium-Tier the cap targets 4,800 visitors per day with 4 to 9 percent reef damage. The programme replaces the chaotic first-come queue with a managed-throughput model that allows operators to plan capex against predictable demand and defend a premium ASP backed by visitor-cap scarcity. DNP expansion to Hin Daeng-Hin Muang and Koh Bida signalled for Q2 2026 with similar fee structure.
