What will you see and do on a Similan Islands day trip from Phuket?

The Similan Islands archipelago forms the Similan National Park, which covers almost 130 square kilometers.

Its name translates to "nine" in Malay, which refers to the number of islands in the chain. Of these nine isles, seven are totally uninhabited, and the remaining two house national park offices.

The Similan Islands were named a national park in 1982 and are characterized by the enormous boulders that line the shores of its beaches.

The islands have gained so much popularity over recent years that in 2018, visitor limitations were put in place to protect the natural environment.

Today, the park allows around 3,000 tourists to set foot on its shores every day. This is a dramatic difference from the 7,000 visitors that used to sail freely into the national park daily.

What brings visitors flocking to the group of islands is the park's diverse sea life. You can snorkel or dive while in the national park and expect to see a plethora of creatures. There are countless fish species roaming the waters of the Similan Islands, including snappers, surgeonfish, giant groupers and butterflyfish.

Octopuses, leopard sharks, whale sharks and manta rays are among the larger beasts you may catch a glimpse of as you move through the seas. Large pods of dolphins reside in the waters nearby to the isles and are most active at dawn or dusk.

Out of the water, you'll find palm civets and flying lemurs, as well as over 20 species of amphibians. The skies above the Similan Islands are also colored with tropical birds, including collared kingfishers and brahminy kites, which you can see on a Similan Islands day tour.

When are the Similan Islands open over the year?

In order to preserve the delicate ecosystem, the Similan Islands are closed to tourists during the monsoon season every year.

You can visit the islands between October and May, however, you will be unable to travel to the archipelago between mid-May, and mid-October. The exact date of closure changes every year, and you should check this before traveling.

Some islands are also closed year-round due to turtle nesting.

When is the best time to visit the Similan Islands?

Day trips to the Similan Islands are spectacular at any time during their open season of October to May. Throughout this time, you’ll experience low humidity, predictable weather and excellent visibility.

For the lowest chance of a rainstorm ruining your adventure, visit the islands between December and March.
