Similan Islands reopen for 2026-27 season on 15 October

The Similan Islands (Moo Ko Similan) will reopen to visitors on 15 October 2026, returning the Phang Nga marine national park to its 2026-27 tourism season. The reopening follows a five-month closure designed to protect visitors during the Andaman monsoon and give marine ecosystems time to recover.
Similan Islands reopening begins on 15 October 2026
The Department of National Parks, Wildlife and Plant Conservation sets the seasonal access period for the park. The official national parks information page states that the Similan Islands open from 15 October to 15 May each year, while the public relations office recorded the 2026 closure from 15 May to 15 October.
That means the first date on which visitors can plan a normal visit in the current season is 15 October 2026. The five-month pause applies to tourism and overnight stays, rather than only to individual beaches or a single trail. The closure also covers the nearby Surin marine national park, although the two parks remain separate destinations in Phang Nga province.
The reopening is a change in access for travellers who could not legally visit the islands during the closed period. The park authorities also used the closure to improve utilities and facilities ahead of the October 2026 season, giving the date a practical significance beyond the usual calendar change.
official seasonal access dates are published by Thailand's national parks department, while the closure announcement for 2026 identifies the affected parks and the five-month period.
Coral reefs and Sail Rock define the island park
The island group lies in the Andaman Sea off Phang Nga province and is managed as a marine national park. The official description refers to coral reefs, marine life, white-sand beaches and the granite formation known as Sail Rock on Island 8.
Sail Rock is linked to a viewpoint above a bay, while the surrounding waters contain coral formations and fish species described by the park authority. These features connect the October reopening directly to the landscape that was protected during the monsoon closure: the date restores access to both land-based viewpoints and marine areas, subject to park rules.
The reopening therefore does not represent the launch of a new attraction. It marks the return of an established protected area after its annual period without tourism. Visitors arriving from Western Europe will find an island park shaped by seasonal access, conservation measures and the conditions of the Andaman coast.
Why the October reopening matters in Phang Nga
The closure is linked to monsoon safety and ecosystem recovery. During the closed period, the authorities also planned improvements to infrastructure and visitor facilities, so the 15 October 2026 date combines the return of access with preparations for the next tourism season.
The park's best-known visual landmark is on Island 8, but the destination is an archipelago rather than a single viewpoint. A visit can involve beaches, rocky formations, reefs and marine wildlife, with the precise experience dependent on the access arrangements and conservation rules in force when the park reopens.
Visiting Similan Islands: what travellers from Western Europe should know
- The 2026-27 season begins on 15 October 2026, and the park remains within Phang Nga province.
- The main access change is the end of the five-month tourism and overnight-stay closure; visits before 15 October 2026 are not part of the reopened season.
- The public relations announcement places the relevant mainland departure point at Ban Thap Lamu pier in Phang Nga province, where boats served visitors before the closure.
- The terrain includes beaches, granite rock formations, a viewpoint at Sail Rock on Island 8 and coral-reef areas, so visits combine exposed coastal ground with marine activities.
- Thailand's official language is Thai and its national currency is the baht.
- Entry requirements depend on your nationality; UK travellers can check the FCDO travel advice at gov.uk/foreign-travel-advice, Irish travellers the Department of Foreign Affairs at ireland.ie.
