What the entry fee actually is
Mu Ko Similan sits in the Department of National Parks' top fee band, Category 4, under a schedule that took effect on 7 June 2022. Foreign adults pay 500 baht and foreign children aged three to fourteen pay 250 baht. Thai nationals pay 100 and 50 baht respectively. You will still find 300 baht quoted for foreign children on older tour pages; that was the pre-2022 rate. Scuba divers pay an additional supplement, widely applied by operators at 200 baht per diver per day, reflecting the fact that divers count against a separate daily quota.
The e-ticket requirement, and why it exists
Mu Ko Similan was one of six parks in the department's e-ticket rollout, and since the 2025–26 season opening on 15 October 2025 an e-ticket has been mandatory. Tickets are bought through the DNP system, in practice via the QueQ mobile app or the department's website, and payment is by card or Thai QR payment. The system issues a code that rangers scan on arrival. The stated motivations were reducing cash handled at remote ranger stations and giving the department a live, auditable count of visitors against the daily cap.
Passport details are not optional
The e-ticket is issued to a named person. Foreign visitors must supply a passport number, and operators booking on your behalf are asked for passenger name, date of birth and nationality as well. Tickets are non-transferable and non-refundable, so a name typo is a real problem rather than a formality. Same-day purchase is possible but closes at 08:00, after which the day's final headcount is fixed. Outside peak periods, buying at least the day before is the practical rule. Around Christmas, New Year, Chinese New Year and Songkran, availability tightens well in advance.
What the fee covers — and what it does not
The entry fee is a park admission, not a tour. It funds rangers, mooring buoys that keep anchors off coral, toilets and waste removal on Koh Miang and Koh Similan, reef monitoring and emergency assistance. One payment covers you until you leave park waters, whether that is six hours on a day trip or several nights aboard a liveaboard; an itinerary that exits and re-enters can incur a further charge. It does not cover your boat, guide, equipment, food or transfers, and it is a separate park to Mu Ko Surin, which charges its own fee.
Is the fee included in your tour price?
This is the most common billing surprise on a Similan day trip. Many operators quote a boat price with the park fee excluded, then collect 500 baht per adult in cash at the pier; others bundle it. Neither is dishonest, but the difference is meaningful for a family of four. Check the inclusions line before comparing prices, and assume a headline price noticeably below the market has the park fee sitting outside it. Where the fee is collected separately, bring baht in cash — card facilities at the pier are not something to rely on.
