Practical
Approx: shown at the Koh Miang HQ anchorage, where fees are verified. Fee: 500 THB per foreign adult and 250 THB per child aged 3–14 (Thai National Parks, page updated June 2026). The Southeast Asia Pilot also lists 400 THB per vessel per day and 400 THB per scuba diver per day (no year given), while Wikivoyage gives a 200 THB diving fee and Khao Lak operators charge 700 THB per diver, so expect a diver supplement and verify locally. Booking: a cruiser on Noonsite (March 2024) booked a crew permit for one or more days in advance through the QueQ app at 500 THB per person per day and received a batch code that rangers accepted. The Southeast Asia Pilot notes that the advance voucher system applies to commercial operators, not private yachts, but warns it may change. Quota: about 3,325 day visitors plus 525 divers per day (Wikivoyage; Thai National Parks gives 3,325). Day-visitor hours are 8am to 4pm. Rules: no fishing, trolling or spearfishing within 5 nm, no anchoring on coral, no single-use plastic, no fish feeding. Islands #1–3 are closed to the public, and Koh Tachai (#11) is closed to landings. Update for 2026: since 15 October 2025 the Similans require an electronic ticket from the QueQ app or e-ticket.dnp.go.th, issued and identity-confirmed before 8am on the day of travel. Tisland Travel (October 2026) gives a combined quota of 3,850 a day (3,325 non-divers plus 525 divers) and confirms that overnight stays on land remain banned.
