Similan / Phi Phi / Surin Permit Checker
Permit availability, fees, closure dates, and advance booking.
What this solves
Thailand's marine national parks have strict permit systems. Similan closes mid-October to mid-November annually for conservation. Maya Bay has rotated closures for reef recovery. Surin has limited daily quotas. This checker tells you whether your travel month is open and how far ahead to book.
How to read results
Each park-month-activity combination shows availability (open/closed), the per-person permit fee, and the recommended advance booking time. Diving requires additional certification check. Snorkelers need only the park entry permit.
Limitations
- Closure dates can shift year to year based on reef recovery.
- Daily quotas for Surin fill 1–2 weeks in advance in peak season.
- Boat access depends on weather; permit does not guarantee entry.
FAQ
When exactly is Similan closed?
Typically closes mid-October and reopens mid-November. The exact dates are set annually by the Department of National Parks.
Is Maya Bay open now?
Maya Bay was reopened in January 2022 with rotation closures for reef recovery (typically 2 months closed for every 4 months open). The current rotation is set by DNP.
Can I get a permit on the day?
For Surin and Maya Bay, day-of permits are unreliable in peak season. Book 1–2 weeks ahead via licensed tour operators. Similan is similar.
