LATEST NEWS: Similan Islands Will Close Again in 2024.


The Similan Islands are located off the coast of Phang Nga Province in the Andaman Sea. These islands are one of the most recognised island groups in the area, and they are renowned for having some of the world’s best coral reefs which makes them an incredibly popular snorkelling and scuba diving destination. The Similan Islands feature large rock formations on the coasts of a number of the Islands, which form a particular and memorable characteristic for this location.

The Time To Visit

With only a few weeks left to visit the spectacular Similan Islands before their scheduled closure, now is the last time to book your private tour with 5 Star Marine.

Similan Islands Closing

Every year, from May 16th until the 15th October 2023 (updated 27.04.2023), the Similan Islands are closed to visitors in order to safeguard the marine habitat and stimulate its recovery. The date changes slightly from year to year, but you can find the most up-to-date information here.

The closing time allows coral reefs, marine life and the beaches all to recuperate from the consequences of tourism; such as the pollution and physical harm which comes with it. This contributes to the Islands’ continued existence as a magnificent and sustainable natural attraction for future generations to enjoy.

In addition, the Andaman Sea receives harsh monsoon weather conditions at this time, which can cause strong waves and winds making for unsafe conditions for both boats and people to get to the islands.

Ecosystem Regeneration

The Similan Islands, despite their popularity, are a vulnerable ecology. Therefore, whilst they are open to visitors, from October each year, the National Park asks that all guests follow the set regulations in order to preserve these Island’s natural beauty. This includes taking care not to harm or disturb coral reefs, avoiding littering or polluting and only trekking on approved routes and walkways so as not to disrupt the delicate ecosystem.

Marine Life

Mu Ko Similan National Park encompasses an area of around 140 square kilometres and includes the Similan Islands. The park is home to a diverse range of marine life, including tropical fish, sea turtles and reef sharks in addition to various bird and mammal species.

Beautiful coral reefs and other rare marine life such as whales, dolphins and Moray eels may be found beneath the amazingly transparent turquoise seas. The coral and marine life in the Similan Islands is so diverse that it is estimated that there are over 500 types of hard and soft coral here.
